Molecular and phenotypic characterisation of French isolates of Diaporthe helianthi / Phomopsis helianthi Munt.-Cvet
Among a French collection of 150 Diaporthe helianthi / Phomopsis helianthi Munt.-Cvet. isolates collected on sunflower since 1995, 4 were chosen for their different characteristics according to their geographic origin and the part of the infected plant where they were sampled (leaf, petiole, capitulum). Phenotypic and molecular characterisation studies were conducted on these isolates. Phenotyp...
متن کاملSclerotinia sclerotiorum (Lib.) de Bary causing Sclerotinia rot in oilseed Brassicas: A review
Sclerotinia sclerotiorum (Lib.) de Bary, the causal organism of stem rot of Brassica and over 500 host plants is distributed worldwide. Sclerotinia rot is menace to cultivation of oilseed Brassica crops in the world. Infection occurs on leaves, stems and pods at different developmental stages, causing seed yield losses of up to 80%, as well as significant reductions in oil content and quality. ...

Four bacterial strains, Pseudomonas chlororaphis (PA-23), Bacillus amyloliquefaciens (BS6), Pseudomonas sp. (DF41) and B. amyloliquefaciens (E16) which had been found to have biocontrol activity in vitro assays against Sclerotinia sclerotiorum, the causal agent of stem rot of canola, were tested for their efficacy in greenhouse and field conditions. Microscopic studies showed that P. chlororaph...
متن کاملبررسی تاثیر سودوموناسهای فلورسنت روی قارچ Sclerotinia sclerotiorum(Lib.)de Bary عامل پوسیدگی ریشه آفتابگردان
خاک مزارع آفتابگردان استان آذربایجان غربی جمع آوری شد، سپس بذر آفتابگردان در گلخانه در این خاکها کاشته شد و از ریزوسفر این گیاهان 45 جدایه سودوموناس فلورسانس با استفاده از محیط S1 جدا گردید. بررسی تاثیر جدایه‌های فوق در جلوگیری از تندش اسکلروت قارچ نشان داد که 26 جدایه مانع تندش اسکلروت قارچ گردیدند که برای آزمایشهای بعدی انتخاب شدند و جدایه‌هایB8،B29 وB38 بیشترین تاثیر را در جلوگیری از تندش اس...
متن کاملMethods of determining the reaction of sunflower genotypes to terminal bud attack by Sclerotinia sclerotiorum ( Lib ) De Bary
as a basis for comparison of the different test methods, since it has been shown that genotype ranking according to reaction to natural attack is stable. Two tests gave results significantly correlated with those of natural attack. A test measuring mycelium extension along the young stem from an explant placed on the terminal bud gave a correlation of r = 0.554 (n = 20). An infection by ascospo...
