Effect of Actinobacteria and Pseudomonas spp. against Sclerotium rolfsii in Groundnut
Groundnut or peanut (Arachis hypogaea L.) is one of the important economic oilseed crops of the world. The cultivated groundnut belongs to family Fabaceae, subfamily Papilionaceae. Groundnut is grown in nearly 100 countries. It occupies 21.7 million ha worldwide with a total production of 38.6 million tonnes during 2011 (FAOSTAT, 2011). Among the soil-borne fungal diseases of groundnut, stem ro...
متن کاملSelection of high temperature and salinity tolerant Trichoderma isolates with antagonistic activity against Sclerotium rolfsii
Trichoderma isolates were collected from varied agro-climatic zones of India and screened for high temperature and salinity tolerance. Among all the isolates tested, T. asperellum, TaDOR673 was highly tolerant to heat shock of 52°C with a mean spore count (log c.f.u/ml) of 4.33. The isolate after recovery from heat shock possessed higher germination rate and biomass production compared to its w...
متن کاملOccurrence of Sclerotium Rot in Allium tuberosum Caused by Sclerotium rolfsii in Korea
In this study, we characterized sporadically occurring sclerotium rot caused by Sclerotium rolfsii in Chinese chive (Allium tuberosum Roth.) in farm fields in Sacheon, Korea. The initial symptom of the disease was water-soaked, which progressed to rotting, wilting, blighting, and eventually death. Further, mycelial mats spread over the lesions near the soil line, and sclerotia formed on the sca...
متن کاملFormation and regeneration of protoplasts in Sclerotium rolfsii ATCC 201126.
AIMS Different cultural conditions for forming and reverting protoplasts were systematically studied to establish a rapid and efficient protocol for Sclerotium rolfsii ATCC 201126. METHODS AND RESULTS Osmotic stabilizer, lytic enzymes and mycelial age were the main factors influencing protoplast yields. An optimized protocol involving 1-h hydrolysis of 45-h-old mycelium with Trichoderma harzi...
متن کاملFirst Report of Sclerotium Rot on Cymbidium Orchids Caused by Sclerotium rolfsii in Korea
Sclerotium rot was found on Cymbidium orchids at Seosan-si, Chungcheongnam-do, Korea, in July, 2010. Symptoms occurred on low leaves, which turned yellowish, after which the entire plant wilted. Severely infected plants were blighted and eventually died. White mycelial mats and sclerotia appeared on pseudobulbs. Based on the mycological characteristics and pathogenicity, the causal fungus was i...
