rhizobium spp. isolates as biocontrol agents of bean damping-off, caused by rhizoctonia solani
the antagonistic effects of rhizobium spp. isolates against rhizoctonia solani (ag-4), the causal agent of bean damping-off were compared with each other in either of the in vitro and in vivo conditions. also their potential to produce such secondary antifungal metabolites as hcn, siderophore and protease were evaluated. the results indicated that, isolate rh3 reduced mycelial growth of r. sola...
متن کاملLiquid 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 ...

Gliocladium virens controlled damping-off of zinnia, cotton, and Disease control efficacy lasted for at least 2 mo when G. virens was cabbage caused by Pythium ultimum or Rhizoctonia solani in nonsterile int...
متن کاملThe Effect of Trifluralin on Rhizoctonia solani (isolate AG4), Causal Agent of Soybean Damping off
Damping off caused by Rhizoctonia solani (isolate AG4) constrains growing soybean in the north Iranian province of Golestan. The pathogen was grown on malt agar containing 0, 50, 100 or 200 ppm trifluralin then its vegetative growth and virulence were evaluated. The response of soybean cv. Williams seedlings grown in soil containing 0, 0.5, 1 and 2 ?g ai g-1 trifluralin was investigated. On mal...
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...
