Path.1 Epidemiological studies on cotton diseases Path.1 (a): Observations on the occurrence of various diseases
Cotton scientists from Regional station, Faridkot conducted survey at regular intervals of farmers field and research farms in cotton growing districts of Punjab. Cotton leaf curl disease (CLCuD), Bacterial Blight (BB) and Fungal Foliar leaf spots (FFLS) were the diseases observed in different districts. The PDI of CLCuD varied from 3.5 to 59.2 %, 29.1 to 53% ; 12 % to 40 % on varieties/hybrids like RS 921, RST-9, F 846, F 505, F 1861 , F 2383, F 2228, US 51 BG II , RCH 776 BG II, Bioseed 6588 BG II and RCH 773 Bt in different villages, research farms of Faridkot, Fazilka and Muktsar districts (Table 1). Bacterial blight was found in traces to 3.1% in Faridkot and traces to 2.1% in Fazilka and traces to 2% in Muktsar on hybrids like Bioseed 6588 BG II, RCH 773 BG II, RCH 776 BG II, US 51 and various entries of co-ordinated trials in different cotton growing areas. The fungal foliar leaf spots caused by Alternaria, Myrothecium and Cercospora, ranged from traces to 3.0%, Traces to 2.4% and Traces to 2.1% DI on RST-9, RS 921, F 846, HS 6, Bioseed 6588 BG II , RCH 773 BG II, RCH 776 BGII and US51 BGII and on different entries of research farms. (Table 1). Six major Blocks were covered in the district Bathinda i.e. Nathana, Talwandi, Sangat, Bathinda, Rampura and Maur by RRS, Bhatinda. During Kharif 2018, severity of the CLCuD was found to be less in the cotton fields of Bathinda district as compared to the previous years. During Kharif 2018, initial incidence of the CLCuD having the disease severity Grade I was noticed in the village Mehman Dwana in the Bathinda district on July 03,2018 in the Bt cotton hybrid RCH 776 BG II. The incidence of CLCuD having the disease severity of grade II-III was noticed in the timely sown (in May)Experimental trial and Grade V-VI in the late sown(in June). The CLCuD PDI ranged from 0-49.17in experimental trial. Incidence of root rot, having the per cent disease severity, ranged from 0- 5% were found in the isolated pockets at 7-8 locations of the cotton field of Bathinda district. An incidence of fungal foliar leaf spots was also noticed but its severity grade was found to be maximum upto 1. After heavy rains during the second fortnight of September, incidence of fungal foliar leaf spot was noticed approximately after 120 days of sowing. Incidence of Bacterial Blight was also noticed in traces at the farmer’s field with maximum grade upto 1. The most popular Bt cotton hybrid sown in Bathinda District was found to be RCH 773 BG II followed by RCH 776 BG II and US 51 BG II. In Talwandi and Maur block of Bathinda district, during the month of June 2018, few plots of the cotton field raised on beds were affected with the accumulation of salts on the raised beds and plants were completely dried. (Table 2 ). The data on disease intensity of leaf curl virus was recorded during Kharif 2018 by surveying the cotton growing areas of Sriganganagar and adjoining areas of Hanumangarh districts of Rajasthan state. Out of four tehsils surveyed in Sriganganagar district, in Sriganganagar tehsil, disease intensity of leaf curl virus was found to be highest i.e. 23.8 per cent. In Srikaranpur, Padampur and Sadulshahar tehsils the average disease intensity was 22.1, 10.7 and 9.5 per cent, respectively. In adjoining cotton areas of Hanumangarh district the average disease intensity was 12.1 per cent (Table 3). The survey was conducted to record the occurrence of different diseases in major cotton growing districts (Hisar, Bhiwani, Fatehabad, Sirsa and Jind) as well as in the non-
ICAR-All India Coordinated Research Project on Cotton – Annual Report (2018-19) F - 2 - traditional areas of Haryana (Mahender Garh, Rewari, Palwal, Jhajar and Rohtak) from June to September, 2018. At HAU research farm cotton leaf curl virus disease ranged from 9.50 to 64.77 per cent. Whereas at farmer’s field the PDI was low as compared to the HAU research farm. The highest per cent disease index (PDI) 33.0 per cent in Nidani district Jind followed by 30.0 per cent in Nidana and Ikkas district Jind and Dhand district Fatehabad (18.3%), in Dhani Sobha district Hisar 28.2 per cent, Meham district Rohtak 18.0 per cent and Kharkari district Bhiwani 13.4 per cent. Whereas, in Mahendergarh, Palwal, Jhajar and Rewari districts PDI ranged from 8.0-13.0 per cent. Among the fungal diseases Myrothecium leaf spot (MLS) PDI varied from 1.0 to 7.0 per cent. Other diseases viz. Alternaria leaf spot (ALS) and Bacterial leaf blight varied from 0-5.2 per cent, Root rot varied from 0-5 per cent (Table 4).
Path.1 (b): Disease progress in relation to weather factors.
Cotton leaf curl viral disease (CLCuD) was first observed on all the varieties in the 26th SMW. Observations on the appearance and progress of CLCuD were taken at weekly interval starting from 25th to 44th meteorological week at Faridkot. It was found that CLCuD % increased up to 44st meteorological week in all the varieties sown. Max PDI attained in CLCuD was 59.30 in variety F 846 . The intensity of disease at intial stage was very less. The bacterial blight was started late in the season in 31st meteorological week with 0.1 % DI. The fungal foliar leaf spots caused by Alternaria, Myrothecium, and Cercospora ranged from 0.1 to 2.9; 0.1 to 2.7 and 0.1 to 2.7 disease index from 31st meteorological week in all the varieties. (Table 5).
Susceptible variety RST-9 of cotton was sown on 25.5.2018 in 545 square meter area following recommended package of practices to record weekly progress of leaf curl disease at Sriganganagar. Leaf curl disease first appeared on 21st June after 26 days of sowing during 25th St. week and the incidence at the end of this week was 5.4 per cent. However in subsequent standard week’s leaf curl incidence in crop showed fast progressive increase reaching maximum level of 100.0 per cent on 27th July during 30th Standard week.
Data presented in Table indicate that disease incidence was increased gradually up to 27th Std. Week (2 July – 8 July) with disease severity of 40.0 per cent. In subsequent 28th to 30th std. week disease progression was found very fast reaching to the level of 100.0 per cent. The overall precipitation from June to August (vegetative phase) during this year was 220.0 mm. The average weekly temperature during this period of June to August remained between 27.3 to 47.6 oC and maximum relative humidity ranged between 40.1 and 80.0 per cent (Table 6).
CLCuD appeared on 5th June, 2018 in the 23rd standard meteorological week after 30 days of sowing and disease incidence was 0.7 which increased upto 95.3 per cent on 39th week and per cent disease index was 0.1 which increased up to 48.7 per cent at Hisar. PDI on 41st week (8.10.18-14.10.18) was maximum, during this period the average maximum and minimum temperature recorded were 32.50 and 17.90oC, whereas, morning and evening relative humidity was from 86 to 42.80 per cent with 6.80 bright sun hours having whitefly population 36.20 per three leaves . The per cent disease index increased upto 48.7 per cent in the second Week of October, 2018. (Table 7).
The leaf curl virus disease initiated in 25th met week (18-24 June) and the incidence reached 100% by 34th week (20-26 Aug) at Sirsa. An increasing trend of whitefly incidence ICAR-All India Coordinated Research Project on Cotton – Annual Report (2018-19)
F - 3 - from 1.3 per 3 leaves up to 16.4 whiteflies per 3 leaves was observed during the season. The maximum temperature ranged from 34.1 to 38.30C whereas minimum temperature was between 21.4 to 27.40C. Relative humidity morning and evening ranged between 65.0 – 83.7 and 48.0-66.9 % respectively. The total rainfall received during this period was 202.5 mm (Table8).
Path.2(a). Screening of AICCIP breeding lines for disease reaction
The breeding lines in various national and zonal trials were screened against important diseases in the area. In each screening trial susceptible checks for the diseases were maintained and their reaction is presented at the end of each table where data from different locations of a trial is pooled. The reaction of a particular entry is considered valid provided there is either susceptible or moderately susceptible reaction in the susceptible check.
The results of National trials are given in Tables – 9 to 14. The results of zonal trials (north zone) are given in Tables 15 – to 18.
Path.2 (b): Confirmation and maintenance of disease resistant lines.
The data presented in Table revealed that out of nine entries tested under field conditions against cotton leaf curl disease (CLCuD) at Faridkot, four entries viz., F 2382, CSH3075, RHCHD1406 and LH2108 showed resistant reaction. Four entries namely , RS 2814, RS 2821, RS 2814, PAUBT-1 gave moderately resistant reaction except RST-9 gave moderately susceptible reaction. Against bacterial blight all entries moderately resistant reaction except RST 9 which gave moderately susceptible reaction. Against fungal foliar leaf spots (FFLS) caused by Myrothecium, Alternaria and Cercospora, three entries viz., RS 2814, CSH3075 and RHCHD1406 F gave resistant reaction. Five entries namely, F2382, RS 2818, RS 2821, LH2108 and PAUBT-1 gave moderately resistant reaction except RST 9 which gave moderately susceptible reaction. .(Table 19).
Path.2 (c) Monitoring of breakdown of resistance against CLCuD in cotton.
In this experiment, three each of tolerant and susceptible varieties against CLCuD and one each of tolerant and susceptible Bt cotton hybrid were selected and sown at three locations to see how their reaction against CLCuD changes over the years. The PDI in case of tolerant varieties/hybrid was much less compared to susceptible varieties/hybrid at Sriganganagar and Bhatinda centers whereas it was almost similar at Hisar (Table 20). However when we look at the reaction category, the tolerant varieties were grouped in categories from R to HS. The susceptible varieties were grouped in categories from S to HS. The tolerant Bt hybrid was grouped from HR to MR and susceptible hybrid from MR to HS category.
Path. 3 (f): Management of sooty mould (Capnodium spp.) in cotton Two experiments were planned during 2018, one as conducted last year where treatments were imposed once the sooty mould had developed to see how much is controlled. whereas another set with same treatments was planned and the interventions were applied at

F - 4 - initiation of sooty mould and was compared with check without intervention. The experiments were conducted in poly house and field.
In poly house experiment at Sirsa, two sprays of Mancozeb 50WP @2.0 g/L followed by Copper oxychloride 50 WP @2.25g/L & Propiconazole showed maximum reduction of sooty mould. In an another poly house experiment at Sirsa, two prophylactic sprays of Propiconazole @1ml/L water followed by Mancozeb 50WP @2.0 g/L & Copper oxychloride 50 WP @2.25g/L showed minimum sooty mould at 30 and 50 days after second spray(Table 21).
In field trial, Three sprays of Copper oxychloride 50 WP @2.25g/L followed by Mancozeb 50WP @2.0 g/L and Propiconazole @1ml/L water showed maximum reduction of sooty mould 15 days after 3rd spray.(Table 22)
Path 3 g: Management of parawilt of cotton (New experiment) Locations(NZ): Field experiment : Bathinda, Hisar. At Bhatinda, treatments Drenching of Plants with mixture of Copper oxycloride (COC) 50 WP@ 25g and 200 Urea in 10 litre of water followed by Cobalt chloride foliar spray @ 10 ppm immediately after occurrence of disease showed maximum recovery of plants from parawilt.(Table 23).
Path.4. (e):Expt.1: Crop loss estimation due to CLCuD and distribution pattern of CLCuD in north zone
Pooled data of Hisar, Faridkot and Rajasthan seed cotton yield reduction (Grade wise from 1-6) due to CLCuD in different Bt hybrids varied from 7.4 to 54.2, 17.4 to 53.3, 16.8 to 52.0 and 15.5 to 52.5 percent in Bt hybrids US-51, RCH 773 BG II, NCS 9013 BGII and Bioseed 6688 BG II respectively. Based on mixed grades it was 33.4, 35.6, 28.7 and 25.7 percent respectively in US-51, RCH 773 BG II, NCS 9013 BGII and Bioseed 6688 BG II (Table 24 ).

NORTH ZONE
The maximum leaf curl disease was noted in Punjab followed by Rajasthan and Haryana during the 2018 season. In Punjab, maximum CLCuD was noted in Fazilka district followed by Muktsar and Faridkot. The Minimum PDI was observed in Bhatinda district. In Rajasthan, Sriganganagar district showed maximum CLCuD followed by Hanumangarh. In Haryana the maximum CLCuD was recorded in Sirsa & Jind followed by Hisar, Fatehabad, Mahindergarh, Rohtak, Bhiwani, Rewari, Palwal, and Jhajjar. (Table 25 ).
Concluded Experiment: Path.3 (e): Innovative interventions for the management of CLCuD.
Based on pooled results (2015-16-2017-18), All the treatments showed numerical reduction of CLCuD over control. Pooled results of different interventions showed lowest PDI in Salicylic acid treatment followed by Difenthiurin (0.1%), Cow urine+Calcium nitrate & mustard oil treatments. Based on pooled data maximum whitefly reduction was noted in Diafenthiuron followed by Neem oil.Among other interventions, Bryonia 30 followed by Butter milk+ Calcium nitrate and butter milk alone showed good reduction of whitefly populations.Highest seed cotton yield was observed in treatment Cow urine+Calcium nitrate followed by Butter milk and mustard oil treatments. Based on economics, the maximum benefit cost ratio was observed in Salicylic acid followed by butter milk, cow urine+calcium nitrate and neem oil treatments and are recommended for their use by farmers.(Tables 26- 29).

Path.1 Epidemiological studies on cotton diseases Path.1 (a): Observations on the occurrence of various diseases CENTRAL ZONE Observations were recorded on occurrence of diseases of cotton at farmers field in Nanded (Maharashtra). The Alternaria was found wide spread disease followed by bacterial blight and grey mildew on G. hirsutum and G. arboreum cotton. The intensity of Alternaria varied from 2.50 to 13.10 PDI, while the intensity of bacterial blight ranged from 1.20 to 7.20 PDI, Grey mildew intensity varied from 0.00 to 0.70 PDI. The incidence of para wilt varied from 0.00 to1.70 PDI (Table 1). Observations were recorded at three crop growth stages on occurrence of cotton diseases on farmers and research field at Akola. Bacterial blight was observed at flowering stage in range of 2.66 to 5.35. The Myrothecium leaf spot and grey mildew were observed from 0.85 to 2.34 and 0.83 to 6.33 percent at flowering stage, respectively. The BLB and grey-mildew disease at boll development state were observed from 0.00 to 6.66 and 1.07 to 4.81%, respectively (Table 2). Survey was conducted on farmer’s field as well as on Research farm of Surat Center (Gujarat). Bacterial leaf blight incidence varied from 0.0 to 19.0 PDI and Alternaria leaf spot disease varied from 0.0 to 8.0 PDI in different cultivars/ hybrids on Research farm. Whereas, in case of farmer’s field, roving survey was mostly carried out on BG II hybrids, the BLB incidence was in the range of 0.0 to 4.5, 0.0 to 5.5 and 2.0 to 4.5 PDI in Surat, Bharuch and Narmada districts, respectively. Moreover, Alternaria leaf spot disease was observed to the tune of 0.0 to 8.0, 0.0 to 10.0 and 0.0 to 1.0 PDI in Surat, Bharuch and Narmada district, respectively. (Table 3). The occurrence of various diseases of cotton was surveyed during Kharif-2018 on farmer’s field of Saurashtra area and at Cotton Research Station, JAU, Junagadh. The disease situation in Junagadh, Rajkot and Amreli districts revealed that alternaria leaf spot (ALS) was recorded in the range of 2 to 14, 2 to 17 and 8 to 12 per cent, respectively; bacterial leaf blight (BLB) 0 to 2.3, 0 to 1.5 and 0 to 1 per cent respectively Grey mildew (GM) was not found in any field. Parawilt was recorded in the range of 1 to 16.0, 0 to 20 and 10 to 15 percent, respectively while root rot and wilt were observed negligible in some locations during the season (Table 4). At Khandwa Myrothecium leaf blight of cotton was first observed in first week of September in the month of Oct. the disease incidence increased upto 21.38 %. The disease incidence at present is 6.83 percent. Bacterial blight was observed in third week of August the incidence increased 18.33% upto month of September the disease incidence decreased to 4.22 percent.

The incidence of New Wilt in Bt hybrids has not been observed in Research Farm and farmer field in vicinity of Khandwa. SOUTH ZONE Observations on the occurrence of the diseases (in farmer’s field and research farms) Dharwad (Karnataka): Survey results indicated the predominance of Alternaria blight (03- 38%) in early stages of the crop growth followed by Grey mildew (04-20%) and Bacterial blight (02-20%). Rust appeared after 120 DAS (up to 35%) (Table 5). Guntur (Andhra Pradesh): Alternaria leaf spot, Cercospora leaf spot, Corynespora leaf spot, bacterial blight, grey mildew and rust were recorded during the surveys conducted from August to January 2019, in cotton growing mandals of Guntur district (1.8 lakh ha) in Andhra Pradesh (Table 6). Intensity of bacterial blight, Alternaria leaf spot, Corynespora leaf spot, grey mildew and rust diseases in various hybrids and varieties of cotton trials conducted at RARS, Lam was also recorded. During August 2018, Alternaria leaf spot (0.0 to 4.75 PDI) was recorded in 7 to 55 days old crop. Bacterial blight was observed in an isolated field at Suddapalli village ()0.0- 10.27%) during September 2018 while Alternaria leaf spot (0.0 to 7.68 PDI), Cercospora leaf spot (0.0 to 4.75 PDI) and traces of boll rot were recorded in 60 to 90 days old crop. During October 2018 Alternaria leaf spot (0.0 to 33.25 PDI) and Corynespora leaf spot (0.0 to 9.5 PDI) were observed in 60 to 120 days old crop. Traces of Corynespora leaf spot and Alternaria leaf spot (1.5 to 20.5 PDI) were recorded during November while Alternaria (1.0 to 10 PDI), grey mildew (0.0 to 7.0 PDI) and rust (0.0 to traces) were observed during December 2018. Rust was major disease (5.0 to 24.0) during January 2019 while grey mildew was of 1.0 to 12.0 PDI. Alternaria leaf spot was to the tune of 2.0 to 19.0 PDI. Alternaria leaf spot was the major disease (0.0 to 23.7 PDI); low intensity of Corynespora leaf spot (0.0 to 5.0% PDI), Cercospora leaf spot (0.0 to 5%), anthracnose (0.0 to 4.0), bacterial blight (0.0 to 2.0 PDI), grey mildew (0.0 to 15%) and rust (0.0 to 20.5%) were observed at Regional Agricultural Research Station, Lam, Guntur during kharif 2018. Phoma blight was observed in few plants of breeding trials during October 2018. (Table 6a) Coimbatore (Tamil Nadu): A survey was undertaken in cotton growing areas of Tamil Nadu viz., Madurai, Virudhunagar, Tirunelveli, Erode, Perambalur and Coimbatore to assess the incidence and extent of cotton diseases. The fields were critically examined for the incidence of diseases and the observations made are presented in (Table 7). In nut shell, the disease surveillance survey undertaken in three southern districts of Tamil Nadu namely Madurai, Virudhunagar, Tirunelveli, Anthiyur, Erode, Thiruvarur and Perambalur revealed the following. 1. Most of the cotton farmers were found to grow predominantly cotton hybrid namely, RCH 659, RCH2, Kaveri, Neo, Ankur and Mithra99.
ICAR-All India Coordinated Research Project on Cotton – Annual Report (2018-19)
F - 33 - 2. In southern Tamil Nadu, Virudhunagar district was peculiar as majority of the farmers did not go for Bt cotton as most of the cotton area in this district is rainfed and farmers do not want to take risk in investing for rainfed cotton. 3. Apart from Bt hybrids, the varieties of TNAU namely SVPR 4 and SVPR 5 were popular among cotton farmers in southern districts especially Virudhunagar and Madurai districts. 4. In general, the disease incidence and PDI were found to be low. The symptoms of diseases namely root rot and Alternaria leaf blight were observed sporadically in the range of 5-10 percent and 5-20 per cent respectively. 5. In Erode and Coimbatore districts of Tamil Nadu, in recent years the incidence of Tobacco streak virus is on the rise and during this year also the incidence ranged from 5-20%. Path.1 (b): Disease progress in relation to weather factors. CENTRAL ZONE Nanded, The first incidence of Bacterial blight was noticed during 41st SMW and intensity was found in the range of 0.70 to 7.20 PDI, while the incidence of Alternaria was observed during 31st MW and intensity was in the range of 0.50 to 13.00 PDI, Grey mildew intensity was observed during 43rd SMW, intensity was found in the range of 0.10 to 0.70 PDI. Para wilt was observed during 33th SMW and ranged from 0.30 to 1.70 PDI, apart from this, no other major diseases was found at research station as well as on farmers field in Nanded district. (Table 8). In the experiment on the progress of BLB disease in relation to weather parameters at Akola,the bacterial blight disease initiated in first week of October (36th SMW) with maximum disease intensity up to 8.9 and 8.0 per cent on LRA-5166 & Bhakti Bt respectively in 44th and 46th SMW. Later decreasing trend was observed on LRA-5166 & Bhakti Bt. The grey mildew initiated in the 41st SMW with 1.7% disease intensity on AKA 8. The maximum disease intensity 8.0% was recorded at 50th SMW. On LRA 5166 and Bhakti Bt maximum disease intensity of grey mildew i.e. 3.7 and 5.5% were recorded, respectively. (Table 9 ) Correlation between the weather parameters and Bacterial blight development was studied on variety LRA 5166 and Bunny Bt at Akola. There was significant negetive correlation of morning humidity and rainfall (at 1 %) with bacterial blight development. Maximum temperature and sunshine hours had positive correlation with BLB disease intensity in both the cotton cultivars. (Table 9a) Surat (Gujarat): During the season, only Bacterial leaf blight disease was found on G. Cot. Hy. 12. The incidence of Bacterial leaf blight disease (BLB) was noticed from 33rd to 50th SMW with the maximum disease intensity in the third week (42nd SMW) of October (18.0 % PDI) i.e. in 42nd Met. week. Incidence of Bacterial leaf blight (BLB) showed positive correlation with the maximum and minimum temperature and sunshine hours for the disease development.(Table 10).

Highest percent disease incidence 42% was recorded during third week of October (43rd SMW). At the time there was maximum temperature 37.50, minimum temperature 20.20 relatively humidity morning and evening 64% and 22% respectively. The first occurrence of BLB was recorded during third week of July i.e. 30th meteorological standard week. The maximum BLB incidence (38%) was recorded during third week of September (38th SMW) and there after it was decline. During 38th SMW the maximum temperature 33.50, minimum temperature 23.90, relatively humidity morning and evening 84% and 54% respectively and rain fall 6.20 mm with 2 rainy days. The grey mildew disease remain absent during the season. (Table 11) Correlation co-efficient(r): The data revealed that Alternaria leaf spot disease found positive correlated for minimum temperature and rainfall with 0.721 and 0.453 respectively while remaining factors viz., maximum temperature, relatively humidity and rainy days were negatively correlated and non significant at 5% level and 1% level. Bacterial leaf blight disease correlation coefficient studies recorded positive correlation with minimum temperature (0.078) and rainfall (0.161), respectively. Remaining all factors viz., maximum temperature, relatively humidity and rainy days were negative correlated at 1% and 5% level of significant. The Grey mildew disease was not occurred during the Kharif-2018 season. (Table 11 (a)). Khandwa (MP): Susceptible cultivar JK-4 was sown on 24/06/2018. Bacterial blight was first observed in traces on 29th Standard Meteorological Weeks (SMW). The Myrothecium leaf blight of cotton was first noted in 32th SMW week. The BLB disease intensity gradually increases up to 39thSMW (18.33%) then decreases upto 50th SMW. Myrothecium leaf disease was also first noted in 32th SMW and increased up to 41th SMW (21.38%). The incidence of Alternaria leaf spot was first noted in 33th SMW and increased up to 43th SMW (23.5%) (Table 12) SOUTH ZONE Alternaria leaf blight was recorded from 31st SMW whereas bacterial blight and grey mildew diseases appeared from 36th and 37th met weeks on different varieties/hybrids at Dharwad, respectively. The maximum incidence for all diseases was noticed between 45-46 weeks (Table 13). The correlations with weather parameters were worked out and are presented below (Table 13 a & b): Maximum and minimum temperature. 1. Alternaria leaf blight: With respect to Alternaria blight, significant positive correlation was observed between the maximum temperature and the genotypes. Significant negative correlation was observed between minimum temperature and genotypes like Abhadita, Jayadhar, Bunny Bt and Dr. Brent Bt. 2.

Rainfall and Rainy days: Significant positive correlation was noticed between total rainfall and GM with respect to Jayadhar other genotypes correlated negatively. And no correlation was noticed between rainy days and the genotypes with respect to all the diseases. (Table 13 a Table 13 b) Guntur (Andhra Pradesh): Jaadoo BG II cotton hybrid was sown on 23.07.18 in an area of 150 sq. m. Weekly observations were recorded on the percent intensity of Alternaria leaf spot, grey mildew and rust diseases after appearance of the disease. The data recorded showed that Alternaria leaf spot appeared in 36th SMW during September 2018 when the mean maximum temperature was 34.930C; mean minimum temperature was 26.010C; mean morning relative humidity of 83.57% (RH I); mean evening relative humidity of 57.57% (RH II); rainfall was nil; sun shine hours were 8.23; wind speed 8.87 kmph and evaporation was 8.86. Alternaria leaf spot attained a maximum PDI of 22.5 on Jaadoo BG II during 43rd standard week i.e., last week of October, during which the mean maximum temperature was 34.160C; mean minimum temperature was 21.270C; mean RH I of 6.86%; mean RH II of 52.43%; rainfall was nil; sun shine hours were 8.54; wind speed 6.59 kmph and evaporation was 5.67. Grey mildew disease appeared in 47th standard meteorological week (SMW) during 3rd week of November 2018 on Jaadoo BG II when mean maximum temperature was 32.70C; mean minimum temperature was 22.890C; mean RH I of. 87.86%; mean RH II of 62.57%, rainfall was nil; sun shine hours were 5.11; wind speed 4.93kmph and evaporation was 6.1. The GM disease progressed and reached PDI of 14.0 during 1st week of January 2019 during which the mean maximum temperature was 29.110C; mean minimum temperature was 14.270C; mean RH I was 90.29%; mean RH II was 61.14%; rain fall was nil, sunshine hours were 6.61, wind speed 3.5kmph and evaporation was 3.58 (Table 14). Multiple linear regression analysis revealed that minimum temperature and RH I significantly influenced the disease intensity (R2=0.985). Evaporation expressed partial influence (R2=0.694) on the progress of rust during kharif 2018. Coimbatore (Tamil Nadu): It could be seen from the (Table 15) that the ALB incidence was not observed upto 40th SMW and the incidence started appearing from 41th and the incidence was observed upto 2nd SMW which was coincided with high relative humidity, cloudy weather with chill night temperature which were conducive for faster spread of ALB in cotton. From 41st MSW to 44th MSW, the PDI of ALB was 5 whereas the incidence started increasing from 45th MSW and during 50th to 2nd SMW it was at its peak ie., the PDI was 13.5-15.0. When compared to November the months of December and January were
ICAR-All India Coordinated Research Project on Cotton – Annual Report (2018-19) F - 36 - chiller and night temperature was still lower which were found to be more conduce for spread of ALB and hence the MSWs from 50th to 2nd experienced higher incidence of ALB. Comparative analysis of incidence of ALB in selected varieties and hybrids in relation to weather parameters revealed that the maximum incidence of Alternaria leaf blight (15.0 and 13.5PDI) was observed in the varieties and hybrids viz, CO14 and RCHIIBGII and the incidence was maximum during peak boll bursting stage. The incidence of TSV was found to be in the range of 3-10% in relation to weather parameters. The disease started surfacing in the fields from 45th SMW. From 45th SMW to 49th SMW the incidence was found to be minimal (3-5%) whereas from 50th SMW to 2nd SMW it started progressing from 6.5 to 10%. Comparatively the variety CO14 and RGHBGII (5-10%) were susceptible to TSV than MCU5 (3-5%). Similarly, assessment of root rot in relation to weather parameters revealed that the incidence of root rot started appearing from 47th SMW and it was found to maximum during 50th SMW to 2nd SMW. Maximum incidence of 16.0% was observed during 50th meteorological week in the variety MCU5 and minimum disease incidence was observed in hybrids RCHIIBGII (10%). Among the three diseases for which data on PDI in relation to weather parameters available, regression analysis was carried out to predict the incidence of Alternaria Leaf blight using five weather parameters as predictor variables. The data related to five weather parameter namely Maximum temperature, Minimum temperature, Morning Relative Humidity, Evening Relative Humidity and Rainfall for the year 2018 was collected from Agro Climate Research Centre, TNAU, Coimbatore. The results of Regression analysis revealed that R2 value was 0.885 which mean that 88.50 percentage change in PDI of Alternaria was explained by the selected five weather parameters. The regression coefficient of individual weather parameters is given in the following Table 15a . Among the predictor variables, only one variable namely RH Morning was found to be significant at 1% level of significance and contributed to the incidence of ALB. This implies that the increase of morning Relative Humidity would increase the PDI of Alternaria Leaf Blight in cotton when compared to other parameters. The prediction equation was fitted and given below. PDI (Y) = 17.849-0.726 (Max.Temp)-1.514 (Min temp)+0.514 (RH Morning)-0.0068 (RH Evening)+0.0018 (Rainfall). The equation could be interpreted as, if all the selected weather parameters are kept constant except RH Morning, one unit increase in RH Morning would increase the Percent Disease Index by 0.514 units. From the 't' value for RH morning it could be interpreted as the one unit increase in RH morning, the incidence of ALB would likely to increase two times. Path.1 (c) Studies on the variability in Alternaria causing leaf spot in cotton. Nanded: Isolated samples of Alternaria were submitted to Cotton Pathologist, Dept. of Plant Pathology TNAU, Coimbatore for further confirmation of Pathogenicity.

F - 37 - Surat:The incidence of Alternaria leaf spot was observed to the tune of 0.0 to 8.0 PDI in (Cv. G. Cot. 100) particularly on the middle leaves with few scattered brown spots. Morphological characters of Alternaria leaf spot disease pathogen was studied by observing slides under a microscope. On the basis of morphological characters, it was identified as Alternaria macrospora, dark brown with concentric rings and 3-4 horizontal septa was observed. Junagadh: The variability test of cotton pathogen alternaria was carried out during kharif- 2018 for confirming of variability in alternaria species of cotton . The disease samples were collected from eight different location of this cotton growing region. The samples were processed for isolation of alternaria from blighted leaves of cotton using standard method. The fungus culture was purified and morphological characters were recorded using compound microscope. The mycelium was septet. The conidia were also septet and produced 2-7 septa. The shape of conidia was oblong, tapering at one end and round on other end. Based on morphological and characters the fungi was identify as Alternaria macrospora. Guntur: During the survey for cotton diseases Alternaria leaf spot samples were collected from farmers’ fields and experimental plots at RARS, Lam and observed for the presence of Alternaria (Table 16). Based on the spore structure the species was identified as Alternaria macrospora. The fungus was cultured and the isolate was sent to TNAU, Coimbatore for molecular analysis. The culture was also submitted to PI (Pathology). Coimbatore: Morphological and pathogenicity studies were carried out for the cultures received from Dharwad, Guntur, Akola, junagardh with respect to incidence of Alternaria leaf blight on cotton. Both the pathogens viz., Alternaria alternata and A. macrospora were found to cause the Alternaria leaf blight on cotton. Hence, variability studies were carried out for both the pathogens. The ITS region from the isolates of Alternaria cultures were amplified by the polymerase chain reaction. All the isolates were amplified at 341 bp fragment length. Path 1 (d): Survey and Epidemiology of TSV CENTRAL ZONE Nanded, During 2018-19, survey was undertaken in eight locations (Aurangabad, Parbhani, Nanded, Hingoli, Latur, Jalna, Osmanabad, CRS, Nanded) of Marathwada region / VNMKV Jurisdiction for TSV incidence. No incidence of TSV was observed. SOUTH ZONE: Guntur During the surveys conducted in Cotton growing districts, Tobacco Streak Virus disease was recorded from August to January 2019. The incidence on different hybrids varied from 0% to <3.0% during October (Table 17 & 17a) . The incidence on different hybrids varied from 0% to <1.0% at Lam farm (Table 18). Progress of TSV disease incidence (%) was in the range of 0.08 % to 42.92% in RCH 2 BG II, however intensity was very low (1.07 PDI) . The incidence was more during September when the crop was at 7 to 8 weeks old and thrips counts were in the range of 0.0 to 3.0 per three leaves. The symptoms were restricted to few leaves and/or branches, mostly one or two spots. The incidence of
ICAR-All India Coordinated Research Project on Cotton – Annual Report (2018-19) F - 38 - TSV disease was less from second fortnight of October onwards and thrips were not found (Table 19) . Coimbatore: The Tobacco streak virus incidence in different cotton growing districts was assessed and the data was given in (Table 20)`. From the table it could be seen that the TSV was noticed in Erode and Coimbatore districts and the range of incidence was 5-20%. The incidence was on the higher side in Erode district than Coimbatore district. In Erode district, on an average 20% incidence of TSV was noticed. In the fields of Department of Cotton, TSV incidence was noticed in the range of 5-15 per cent. The incidence was found to be more pronounced in CO14 (15 %) than MCU 7(5%). Path.2(a). Screening of AICCIP breeding lines for disease reaction The breeding lines in various national and zonal trials were screened against important diseases in the area. In each screening trial susceptible checks for the diseases were maintained and their reaction is presented at the end of each table where data from different locations of a trial is pooled. The reaction of a particular entry is considered valid provided there is either susceptible or moderately susceptible reaction in the susceptible check.

ICAR-All India Coordinated Research Project on Cotton – Annual Report (2018-19) F - 42 - Conclusion: Treatment of module 6 (Seed Treatment - PF CICR @ 10 g/ kg of seed + Soil Application of Trichoderma viride @ 2.5 kg/ ha TV- TNAU1 in 250 kg of vermicompost or FYM and foliar spray Kresoxim methyl @ 1ml/ lit followed by COC (0.3 %) + Streptocycline (0.01 %)) with two sprays first from the initiation of the disease and second after the interval of 15 days recorded the lowest incidence of Bacterial leaf blight and Alternaria leaf spot diseases of Cotton and recorded the highest seed yield in module 6 (2589.44 kg/ha) followed by module 5 with 2350.22 seed yield kg/ha. Recommendation: Cotton growing farmers of South Gujarat region are advised the following Integrated Disease Management module (IDM) for the management of Bacterial leaf blight (BLB) and Alternaria leaf spot (ALS) diseases of cotton, seed treatment, soil application and two sprays first at the initiation of the disease and second at 15 days after first spray is effective in managing the diseases and increasing the cotton seed yield. Path. 3 (f): Management of sooty mould (Capnodium spp.) in cotton In field trail at Coimbatore, the maximum reduction was observed by Copper oxychloride 50 WP @2.25g/L followed by Propiconazole 25EC @1ml/L, Copper oxychloride 50 WP @1.75g/L., while at Junagarh (Aphid) the the maximum reduction was observed by by Propiconazole 25EC @1ml/L, followed by Copper oxychloride 50 WP @2.25g/L & Mancozeb 50 WP @ 2g/L. The seed cotton yield was in similar trend to the reduction in sooty mould (Table 66). Path 4 g: Management of parawilt of cotton (New experiment) Nanded: Highest percent recovery (90%) was observed in treatment T5 (Drenching of affected plants with a mixture of Copper oxychloride 25g + 200g Urea in 10 ltr of water) followed by T 4 (Foliar spray of Pseudomonas fluorescens @ 10ml/litre of water). (Table 67a) Akola: After 24 hr of the treatment the observations were recorded on recovery of the plants, where the treatment T5 (Drench Plants with mixture of Copper oxycloride (COC) 50 WP@ 25g and 200 Urea in 10 litre of water) and T1 (Cobalt chloride foliar spray 10 ppm foliar spray immediately after occurrence of disease) which showd 75 and 50% recovery of the plants. Rest of the treatment showed 25% or below recovery of the plants . where control plot showed no recovery. Treatment T 5 followed by T1 (Cobalt chloride foliar spray 10 ppm foliar spray immediately after occurrence of disease) & T 4 (Foliar spray of Pseudomonas fluorescens @ 10ml/litre of water (University strain)) were found superior in terms of seed cotton yield than rest of the other treatments.(Table 67b) Junagarh: Out of seven treatments, cobalt chloride 10 ppm significantly superior with 29 percent recovery of parawilt as compare to control 1.7 per cent recovery respectively. Vigor of plant, root volume, root weight and shoot volume were remain significantly superior as compare control. High root volume recorded 35.5 cm2 in cobalt chloride 10 ppm at par with Pseudomonas fluoresces 35.3 cm2 as compare to control 23.7 cm2. Higher root weight recorded 22.6 gm in carbendazim 50 WP at par with sodium benzoate 50 ppm 22.4g as compare to control 18g. In case of shoot high shoot volume 97.6 cm2 was recorded in

Maximum shoot weight 63.4g sodium benzoate, shoot length 113.4 cm in cobalt chloride 10 ppm, no of fruiting branches 12 inP fluoresence, no of open boll 34.3 in Pseudomonas fluoresces , boll wt 5.4 in Sodium benzoate and yield 3665 kg/ha in salicylic acid were recorded.(Table 67c) Agron. V: Technology for organic cotton production Surat (G. Cot. 20): In this experiment, total eleven different treatment combinations were evaluated against the Bacterial leaf blight and Alternaria leaf spot disease, out of which six different combinations i.e. T1, T2, T3, T7, T9 and T11 observed as moderately resistant, four treatment combinations i.e., T4, T5, T6 and T10 as disease free against the Bacterial leaf blight disease. Whereas, in case of Alternaria leaf spot, only one treatment combination viz., T1 [Absolute control (No organic and Inorganic)] was categorized under moderately resistant (MR) rating and other treatment combinations were disease free. (Table 68a). Junagarh (G. Cot. 20): Per cent disease intensity of bacterial leaf blight and Alterneria leaf spot for 1 to 11 treatments results were statistical non significant. For the bacterial blight minimum disease intensity 0.5 was recorded in control treatment-and maximum recorded in treatment T6 while alternaria leaf spot minimum disease intensity 3.64 percent was recorded in treatment-4+5+6 and maximum recorded in control treatment-2 ie 4.20 percent. Medium reddening were recorded for all treatments. Root rot and grey mildew were not observed (Table 68b). Akola (AKH-1301): The maximum initial disease i.e 7.8% of bacterial blight was recorded in control , while the lowest was observed in treatments T7 and T11. After the treatment the lowest disease intensity of BLB was recorded in T11 i.e 1.2% followed by T9 and T10. Similarly, the lowest percent disease intensity i.e 3.40 of Myrothecium leaf spot was recorded in treatment T8 followed by T10. Rest of the treatments were at par with each other. Minimum per cent disease after treatment was recorded in treatment 11 and 10. Regarding the grey mildew initially all treatments showed at par with other percent disease intensity. After treatment that lowest intensity i.e.1.98 was recorded in T11 followed by T10, T8 and T9. When the control showed maximum disease intensity 4.16%. Remaining treatments found at par with other (Table 68c). Dharwad (G. arboreum): The results indicates that, the treatment no.2 Control (RDN through inorganic) has least incidence of Alternaria blight, Bacterial blight, Grey mildew and Rust with higher yield. But treatment no.11 was on par with no.2 if we consider the cotton equivalent yield as it was a combination of treatment no.4, 5 and 7 with least incidence of diseases (Table 68d).
