VALIUSHKAITE Plant Protection Laboratory, Lithuanian Institute of Horticulture, LT-4335 Babtai, Kaunas District, Lithuania E-mail: [email protected] Abstract Leaf spot pathogen is characterized as a highly developed parasite after investigation of development peculiarities of the fungus in pure culture and natural conditions. The degree of correlation depended on the medium. Impact of incubation temperature on Blumeriella jaapii (Rehm) Arx growth was different. Fungi colonies formed more intensively and their diameter increased significantly under higher temperature. Optimal conditions for the disease prevalence are 15–20°C and moisture. Relative humidity and precipitation influenced maturation of ascomycetes and discharge of ascospores (r = +0.89). Microscopic analysis of leaves showed that during winter thaw, when the average temperature is about 0 ± 5ºC and relative humidity is higher than 70%, was possible to detect mature ascomycetes and conidia. It is possible to affirm that lower temperature than it was assumed is sufficient for formation of ascomycetes.

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades.

  • Cherry Leaf Spot, RPD No
    report on RPD No. 800 PLANT September 1995 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN CHERRY LEAF SPOT Cherry leaf spot is caused by the fungus Higginsia (Coccomyces) hiemalis. It is one of the most serious diseases of sweet and sour cherries in the Midwest. Trees are often defoliated by midsummer and sometimes produce dwarfed, unevenly ripened, soft, and watery fruit with an insipid taste. Repeated defoliation results in: (1) devitalized trees that are more susceptible to winter injury, (2) small and weak fruit buds; (3) the death of fruit spurs; (4) a reduction of fruit set and size; (5) reduced shoot growth; and (6) tree death. SYMPTOMS Figure 1. Spots on cherry leaves begin as discrete brown spots with a distinct border. Cherry leaf spot generally affects the leaves, but lesions can occur on the fruit, leaf stems (petioles), and fruit stems (pedicels). During the latter part of May and the first half of June, small circular purple spots appear on upper leaf surfaces (Figure 1). These spots gradually enlarge to 1/4 inch in diameter (6 millimeters) and turn reddish brown to purple with a definite border. On sweet cherry leaves the lesions are often larger and more nearly circular than those on sour cherry. Lesions often merge, producing a large irregular spot. During damp weather, white to light pink masses of sticky spores (conidia) form on the underside Figure 2. Leaves, particularly on sour cherries, turn bright of the leaves in the center of the spots. After six yellow immediately prior to dropping.

  • Fungicide Application and Residues in Control of Blumeriella Jaapii (Rehm) Arx in Sweet Cherry
    Emirates Journal of Food and Agriculture. 2021. 33(3): 253-259 doi: 10.9755/ejfa.2021.v33.i3.2659 http://www.ejfa.me/ RESEARCH ARTICLE Fungicide application and residues in control of Blumeriella jaapii (Rehm) Arx in sweet cherry Vladimir Božić1, Slavica Vuković2, Mila Grahovac2, Sanja Lazić2, Goran Aleksić3, Dragana Šunjka2 1CI “Plant protection”, Toplicki partizanski odred 151, Niš, Serbia, 2University of Novi Sad, Faculty of Agriculture, Trg Dositeja Obradovica 8, Novi Sad, Serbia, 3Institute of Plant Protection and Environment, Teodora Drajzera 9, Belgrade, Serbia ABSTRACT Fungicides are significant disease control tool in increasing agricultural production, however, their intensive application has led to environmental problems including health hazards. To minimize harmful effects of the fungicide application in sweet cherry orchards, it is necessary to use them in accordance with the good agricultural practice and to monitor presence of their residues. Cherry leaf spot caused by Blumeriella jaapii is a significant sweet cherry disease which control is heavily dependent on fungicide treatments. In this study, effects of fungicide treatments against B. jaapii and fungicide residues remaining in sweet cherry fruits after the treatments were evaluated, and the causal agent of cherry leaf spot was confirmed on cherry leaves from untreated control plots using conventional phytopathological techniques (isolation on nutrient media and morphological traits of developed fungal colonies). The trial was set up at two localities in south Serbia (District of Niš), in sweet cherry orchards, according to EPPO methods. Fungicides tested against B. jaapii were based on dodine (650 g a.i./kg) WP formulation, at concentration of 0.1% and mancozeb (800 g a.i./kg) WP formulation, at concentration of 0.25%.

    SNA Research Conference Vol. 56 2011 Pathology and Nematology Pathology Section 192 SNA Research Conference Vol. 56 2011 Determine the Efficacy of Biological Fungicides for Control of Pythium Stem and Root Rot in Poinsettia Mengmeng Gu, Ph.D, Plant and Soil Sciences Maria Tomaso-Peterson, Ph.D, Entomology and Plant Pathology Yan Zhao, Plant and Soil Sciences Mississippi State University, MS 39762 [email protected] Index words: P. aphanidermatum, poinsettia stem and root rot, biological fungicides, conventional fungicides. Significance to Industry: Pythium stem and root rot is considered the most consistent and serious soil-borne disease problem in poinsettia production. Production greenhouse management practices typically include a fungicide drench when cuttings are transplanted. The standard conventional fungicide in the industry is mefenoxam (metalaxyl) (Subdue Maxx) a high risk fungicide for resistance, which targets RNA polymerase I in nucleic acid synthesis. Fungicide insensitivity metalaxyl exists in P. aphanidermatum isolated from turfgrass as well as poinsettia roots. Resistance management is a vital component of greenhouse production of floriculture crops when pathogens such as Pythium spp. are the target fungi. A key component of resistance management is integrating biofungicides into a disease management program. Nature of Work: Pythium stem and root rot is favored by cool, saturated, poorly drained soils. Moderately low soil temperatures reduces water usage by plants, which favors Pythium stem and root rot in greenhouse production systems. Other factors that favor disease development in poinsettias include excessive fertilizer levels and high pH. The pathogen typically attacks below the soil surface and may extend up into the base of the stem.

The Cornell University first ascospores become mature about the end of bloom and are discharged into the air during rainy periods. Ascospores continue to mature and be discharged until about 6 wk after petal fall. The optimal temperatures for ascospore discharge are 61°F (16°C) and higher, whereas very few ascospores are discharged at temperatures below 46°F (8°C).

Pochubay and N. Rothwell We were grateful to have warmth and sunshine on Wednesday and Thursday, and we observed many bees visiting cherry flowers on those two days while we were collecting data for the pollination project. Growers throughout the region took advantage of the dry weather and protected flowers and leaves from potential disease infections. On Thursday, we observed some damage to unopened cherry buds and blossoms due to overnight cold temperatures in Leelanau County. While this damage was primarily found in low-lying areas within orchards and in trees along orchard edges, we did notice some damage in trees on good fruit sites north of the research station; if orchards had good pollination, we anticipate a normal crop in these blocks. Overnight (15 May) temperatures were warmer in the upper 40s and 50s, but wet conditions returned early this morning. Currently, temperatures are predicted to continue to warm up on Saturday and Sunday, and although there is no rain in the forecast for Saturday, there is a chance of rain on Sunday.

  • Blumeriella Jaapii
    DETECTION OF BOSCALID RESISTANCE AND THE H272R MUTATION IN THE SDHB GENE OF BLUMERIELLA JAAPII By Cory Alan Outwater A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Plant Pathology – Master of Science 2014 ABSTRACT DETECTION OF BOSCALID RESISTANCE AND THE H272R MUTATION IN THE SDHB GENE OF BLUMERIELLA JAAPII By Cory Alan Outwater Cherry leaf spot (CLS), caused by the fungus Blumeriella jaapii , is a major disease of tart cherry (Prunus cerasus ) trees, which uncontrolled leads to early defoliation. Pristine, a commonly-utilized fungicide for CLS management in Michigan, is a premix of boscalid, a succinate dehydrogenase inhibitor, and pyraclostrobin, a quinone outside inhibitor. Reduced efficacy of Pristine for CLS control observed in field trials and commercial orchards highlighted the importance of resistance monitoring. A total of 1,288 isolates from commercial orchards and 111 isolates from non-treated trees were collected in 2010 and 2011 and assayed on boscalid-amended media at concentrations of -1 0, 0.1, 0.5, 1, 2.5, 5, 10, and 25 µg ml . The minimum inhibitory concentration (MIC) of boscalid was determined after incubation at 23 ºC for 14 days . Isolates from non- -1 treated trees had MIC values ranging from 0.1 to 0.5 µg ml while isolates from -1 commercial orchards ranged from 0.1 to > 25 µg ml . Isolates with MIC values of > 25 -1 µg ml were considered resistant and comprised 22% and 35% of isolates in 2010 and 2011 respectively. Sequencing of the SDHB gene of resistant isolates led to the detection of the amino acid mutation H272R known to confer boscalid resistance.
