a survey on biocontrol of rhizoctonia solani kuhn damping-off of tomato with bacillus subtilis
in this research, the antagonistic effects of bacillus subtilis isolates against the causal agent of tomato damping-off, rhizoctonia solani were surveyed under laboratory and greenhouse conditions. isolates b4 and b18 showed the most inhibition ratio in the volatile and non-volatile metabolites tests which were 50.3% and 58.6% respectively. the six out of 25 isolates studied more and their anta...
متن کاملThe Impact of Biofilm Forming Rhizobacteria on Rhizoctonia solani Damping-off of Tomato Running title: The Impact of biofilm forming rhizobacteria on Rhizoctonia solani
در این مطالعه، ۱۸۰ ریزوباکتر از مزارع مختلف استانهای آذربایجان شرقی و غربی جداسازی شدند. این جدایه‌های باکتریایی بر اساس پتانسیل آنتاگونیستی خود علیه Rhizoctonia solani و توانایی تشکیل بیوفیلم قوی غربال شدند. از بین این جدایه‌ها، ۴۹ جدایه بیش از ۳۰ درصد فعالیت آنتاگونیستی علیه R. solani از خود نشان دادند. روش‌های متفاوتی برای غربال جدایه‌هایی با توانایی تشکیل بیوفیلم بالا مورد استفاده قرار گرفت...
متن کاملphenotypic and genotypic study of pseudomonas fluorescens strains pgu0 and assessment of its biocontrol against rhizoctonia solani, the causal agent of bean damping- off
fluorescent pseudomonads producing 2,4-diacetylphloroglucinol (dapg) antibiotic have been well studied for use as biocontrol agents around the world. pseudomonas fluorescens pgu0 strain was isolated from the rhizosphere of sunflower in bushehr province. dual culture test showed that the strain had antagonistic activity against rhizoctonia solani fungus on different media cultures; moreover, und...
متن کاملEssential Oil of Mustard to Control Rhizoctonia solani Causing Seedling Damping off and Seedling Blight in Nursery
The essential oil extracted from mustard (Brassica rapa) seeds was evaluated for its effect on suppression of Rhizoctonia solani growth in vitro, and in field soils, for reducing saprophytic substrate colonization and seedling damping off and blight using snap beans as indicator plant, the in vitro growth was completely inhibited at a concentration of 50 μl/l. The saprophytic substrate coloniza...
متن کاملStudy the Efficacy of Pseudomonas fluorescens against Sheath Blight in Rice by Rhizoctonia solani
Rice (Oryza sativa) is India's pre-eminent crop, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. Moreover, the country has the biggest area under rice cultivation, as it is one of the principal food crops. India is one of the leading producers of this crop, with a production, productivity of 105.48 million tons and 2391 kg per hec...
