MAIN STAGE PEST & ADVISORY CROPS DISEASES Boro Rice Sheath Blight, Yellow Sheath Blight: For Control spray Stem borer, Bacterial Propiconazole 25% EC 1 ml/lit, leaf blight Validamycin 2 gram/lit of water. Yellow Stem borer: To control Spray Fipronil 1.5 ml/lit of water or Cypermethrin 2 ml/lit of water. Bacterial leaf blight: Spray Agrimycin 5 gram/18 lit of water. Maize Tasseling Fall Armyworm, Fall Armyworm: Infestation of the Fall Corn borer Armyworm may arise. Spray Emamectin Stem Benzoate 7 gram/ 15 liter of water or BorerHarvesting Emamectin Benzoate+ Novaluron 5-6 ml/ 15 litre of water during evening time to control during the initial infestation. Weeding can be done at 20-21 days old plants. A hand weeding can be beneficial at this time. To protect the crop from chilling injury, apply Potash in the appropriate amount. Apply Nitrogen @ 3 kg/bigha at Knee high stage. In Maize field if corn borer found in the field, spray cypermethrin 2ml/ litter of water. If stem borer observed apply Phorate 10G @ 4kg/acre at the time of second earthing up. Give irrigation if needed. Harvesting: In the fields where the cobs are near the maturity stage stop irrigation those fields, and start harvesting after 5 days. Tobacco caterpillar: The small caterpillars after coming out from eggs eat Chlorophyll from the bottom side of the leaves and show burned dry spots in leaves. Big and old caterpillars cut the stems of the small plants and cut the leaves of the old plants. During day time it hids in the shed of leaves and in the cracks of soils. In per square meter if 6 caterpillars are found then control is necessary. Control: 1) In the field if we keep stubbles then caterpillars took shelters Tobacco caterpillar, inside the stubbles then it is easy to collect Tobacco Mosaic and burn caterpillars. 2) Spray 1.5-gram B.T Tobacco Virus or 3 mili azadirachtin 1% per liter of water. 3) If needed 12 kg Chlorpyriphos 1.5% dust or 12 kg Fenvelarate 0.4 dust can be broadcasted. Tobacco Mosaic Virus: The infested leaves show characteristic mottling with light and green patches and seedlings are stunted. Control: Workers should disinfect their hands with soap and running water before weeding or handling seedlings. Disease seedlings should be removed and destroyed. Workers should not chew or smoke while at work in nursery. Cultivate high protein containing Moong bean in short time, minimum investment and with very limited irrigation. It will simultaneously increase your income and Field soil quality. During March complete the preparation, sowing with seed rate of 2.5-4 kg/bigha in Moong Seed line sowing. Seed treatment: for seed use Bean collection, treatment Mancozeb 75% 3 gram or Thiram Seed 75% 2 gram or Captan 75% 2 gram. treatment Rhizobium treatment must be done 7 days before seed treatment. Cultivar: Sonali, Panna(B-105), Samrat (P.D.M 84-139), Basanti (P.D.M 84-143). Apply Urea 5.74 Kg, SSP 33.25 Kg, MOP 9 kg per Bigha. No need of FYM application.

Present weather condition is favorable for sowing of Jute. Complete the land preparation as soon as possible. The seeds Field of the jute are so small that it needs well preparation, Jute pulverized soil for sowing. So minimum 2 Seed tillage is required for fine soil. Collect good collection quality seeds of JRO-87, JRC 1108, JRO 232. Apply 100-1000 kg of FYM per acre. Maintain good drainage system. Tea Thrips Symptom: Matured and small insects attack small leaves. Insects eat the sap released from infected leaves. Parallel brown strips can be seen on the upper side of the leaves. Ultimately leaves dries up and growth stunted. Control: 1) Maintain the shade in the tea garden because infestation of thrips is more in unshaded areas. 2) Spray 2 ml dimethoate or 2.5 ml Chlorpyriphos, 2 ml Deltamethrin per one liter of water. White fly- Kindly do not use same pesticide regularly, because the insects develop resistance against that single pesticide. So use the written pesticide alternately for better result. Control: SprayImidacloprid (18.7% S.L) 0.8 ml/lit of water or Acidamiprid 1 ml/lit of water or Diafenthiuron 12.5 gram/ 15 lit of water. White fly, Flower Tomato Flower drop: Due to water stress, drop, Late Blight deficiency of boron or due to hormonal disbalance flower drop occur. Control: Apply timely and required amount of irrigation. Spray Boron 20% 2 gram/lit during early flowering and 15 days later. Late Blight: Be aware of late blight. If occur spray Azoxystrobin + Tebuconazole 1.5 ml/lit of water. Sprayed of Sulphar or Sulfex (Liquid) @ 2ml per liter of water for flower initiation of Litchi Flowering -- Mango and Litchi. Apply 25 kg FYM, 500 gm Nitrogen and 1 kg of Phosphoras and Potash/ tree in ring basin. To prevent fruit drop and increase fruit size of mango spray planofix/thaitozyle @ Mango Marble Size Fruit drop 3ml/15liter of water along with compound micro nutrient @ 45gm/15liter of water.

Bacterial wilting-Wilting starts at the top when the plant starts flowering and fruit setting and eventually the whole plant shows wilt symptoms Cure: Infected plants must be eradicated. Roots of the seedlings must be treated (2.5gm carbendazim + 2 ml Teramycin capsule/litre water) before planting. Bacterial wilting/ Bleaching powder (3kg/acre) can be applied Brinjal White fly/Fruit & with irrigation water. Shoot borer White fly -Cure: 1) 2nd Day spray Difenthiuron 12.5 gram and Azoxystrobin + Tebuconazole 25 ml per 15 liter of water . 2) After 7 days spray Diafenthiuron 12.5 gram per 15 liter of water. During this period attack of fruit & Shoot borer may be seen in brinjal plant. Spray cartop hydrochloride 50% SP @ 1g/lit. of water.

Cattle Fodder crops (Alfalfa) should be irrigated every 12-14 days respectively at this Fodder Disease weather condition. In this month care needs crops to be taken to prevent diseases caused by hot weather. General Ulcer, Lise To maintain the quality of Dolomite Fish @10kg/bigha of area. Ulcer: To control the ulcer apply mixture of Calcium Carbonate 15 kg and Turmeric powder 1.5 kg/ bigha area. After 7 days apply Potassium permanganate 250 gram per bigha.
