tailieunhanh - Evaluations of fluorescent Pseudomonads against collor or root rot of soybean caused by Sclerotium rolfsii

Collor or root rot of soybean is an important soil-borne fungal disease caused by Sclerotium rolfsii causing up to 5-50 per cent of yield losses annually. The present investigation was undertaken on effect of fluorescent pseudomonads on collor or root rot management in soybean. Sixty two different pseudomonad isolates were evaluated for their antagonistic activity against S. rolfsii under in vitro condition. Per cent inhibition of mycelial growth of S. rolfsii by pseudomonads ranged from to . Fifty one isolates showed antagonism against the pathogen. Five isolates BFP22, BFP38, DFP47, DFP48 and DFP62 were found potent with 45. 56 - per cent inhibition of mycelial growth against S. rolfsii. They were further evaluated in greenhouse as seed treatment and soil application. Fluorescent pseudomonad isolate DFP48 was found potent and promising as it reduced the disease to the maximum extent of per cent over pathogen alone control ( %). | Evaluations of fluorescent Pseudomonads against collor or root rot of soybean caused by Sclerotium rolfsii
