Liquid culture production of microsclerotia and submerged conidia by Trichoderma harzianum active against damping-off disease caused by Rhizoctonia solani.
Media and culturing protocols were identified that supported the formation of submerged conidia and microsclerotia (MS) by Trichoderma harzianum Rifai strain T-22 using liquid culture fermentation. Liquid media with a higher carbon concentration (36 g L(-1)) promoted MS formation at all C:N ratios tested. Hyphae aggregated to form MS after 2 d growth and after 7 d MS were fully melanized. This ...
متن کاملdefense responses of cotton to trichoderma spp. and its influence in control of seedling damping-off by rhizoctonia solani
damping-off of seedling is a major disease of cotton in iran. disease may become epidemic in soil with low temperature and high moisture if seed treatment isn’t done. recently, trichoderma spp. are considered as one of the biological control methods of seedling damping-off. one proposed mechanism for biocontrol in trichoderma spp. is stimulation of host defense responses and induction of resist...
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 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...
