The influence of Arbuscular mycorrhiza fungi (AMF) (Glomus deserticola and Gigaspora gigantea) were evaluated on drought tolerance and charcoal rot disease of cowpea genotypes: IT90K-277-2, IT84S-2246-4 and IT06K123-1. IT90K-277-2 and IT84S-2246-4 were sown in 3 kg of sterilized soil for drought experiment with five treatments. Treatment was established thirty days after germination with inocul...
Background: Chickpea wilt complex caused by several soil-borne pathogens is the major yield-reducing malady worldwide. Biological control one of best, low-cost and ecologically sustainable method for managing plant diseases pathogens. Methods: In this present investigation Panchagavya Trichoderma spp. were evaluated following poisoned food technique dual culture against causing i.e. Fusarium ox...
macrophomina phaseolina is one of the major yield limiting factors of melons in tropical and subtropical regions. for eco-friendly and effective management of the disease, 24 gamma induced mutants from trichoderma harzianum were evaluated against three isolates of the pathogen representing three geographically different regions viz. khorasan (isolate 1), garmsar (isolate 2) and khuzestan (isola...
Macrophomina phaseolina is a soil-borne fungal pathogen that causes the charcoal rot disease in many plant species. This disease causes many problems to the soy industry as no consistently effective control has been found. Using Medicago as a model, we study the molecular interactions between the pathogen and its plant host. A microarray chip was used to measure the changes in the expression le...
ABSTRACT The biochemical defense mechanisms of amphibians involve cutaneous secretions bioactive molecules with antimicrobial activity. This study evaluated the in vitro activity methanolic extracts from two amphibian species Bufonidae family, Rhaebo guttatus and Rhinella marina, control phytopathogens Fusarium udum, solani, Colletotrichum truncatum, Aspergillus flavus, Rhizoctonia Macrophomina...
on the basis of preliminary in vitro screening tests, a competent strain of pantoea agglomerans ena1 (p. agg. ena1) recovered from soybean nodule was evaluated for its antagonistic activity against macrophomina phaseolina causal agent of charcoal rot of soybean. the results of various in vitro assays showed that p. agg. ena1 is capable of exerting strong antagonistic effect against m. phaseolin...
in vitro antifungal activity of silver nanoparticles, at concentrations of 6, 8, 10, 12, 14 and 16 ppm, was studied on five phytopathogenic fungi, and a biocontrol agent. then effect of silver nanoparticle at 6 ppm (optimum concentration) was evaluated on macrophomina phaseolina in greenhouse. for in vitro experiment, the fungal isolates were grown on potato dextrose agar medium amended with si...
به منظور تعیین عوامل پوسیدگی طوقه و ریشه گوجه فرنگی در شهرستان مرودشت طی دو فصل زراعی 89-88 از مزارع گوجه فرنگی مناطق حومه شهر مرودشت نمونه برداری به عمل آمد. قطعاتی از بین بافت های سالم و پوسیده ریشه و طوقه بعد از ضد عفونی سطحی، روی محیط های غذایی اسیدی و غیر اسیدی عصاره سیب زمینی آگار کشت گردید. از کشت نمونه ها 80 جدایه متعلق به 17 گونه جدا گردید. بر اساس آزمون های بیماری زایی، گونه های pythi...
charcoal rot caused by macrophomina phaseolina is an injurious and economically important disease which causes heavy loss of yield to field and horticultural crops. thirty-three isolates of m. phaseolina were obtained from different host plants such as: soybean (glycine max.), melo (cucumis melo), bean (phaseolus vulgaris), pea (pisum sativum), pinus (pinus sp), blak-eyed susan (rudbeckia fulgi...
بیماری پوسیدگی ذغالی سویا که به وسیله قارچ macrophomina phaseolina ایجاد می شود، یکی از مخرب ترین بیماری های سویا در سطح جهان می باشد. در ایران نیز این بیماری در بسیاری از مناطق کشت سویا، خسارت قابل توجهی را به این محصول وارد می کند. به منظور بررسی تنوع ژنتیکی و بیماریزایی در جمعیت این بیمارگر، در سال 1385 مناطق کشت سویا در استان های گلستان، مازندران، اردبیل و لرستان مورد بازدید قرار گرفت. نمون...
