dc.description.abstractDrechslerella brochopaga Drechsler, a strangulating nematode-trapping fungus was studies for their adoptability in soil and their tolerance against some common fungicides. D.brochopaga was isolated from horticultural soil of Baberu, Banda. The fungus was characterized and identified by the use of relevant literature. The fungus was found to effectively capture and kill the 96.4 per cent second stage juveniles of Meloidogyne incognita by its three celled constricting ring produced on hyphae within 3 days. The study of adaptability of D. brochopaga in various agricultural and horticulture soil of Banda revealed that this fungus is frequenlty formed conidial trap in vicinity to soil and parastize nematodes. The study of the tolerance of conidia of D. brochopaga with soil amended with different concentrated of common fungicide indicate that this fungus is highly toxic to chlorothallonil was various range of tolerance/sensitivity with common fungicide. Conidia of D. brochopaga were found most sensitive to chlorothalonil and propineb at 10 µl ai kg-1 concentration followed by carbendazim, mencozeb, copper oxychloride, copper sulphate, thiram which inhibited the conidial trap formation at 25 mg ai kg-1 ppm. Tebuconazole inhibited completely inhibited the fungus at 100 µl ai kg-1 whereas Metalaxyl and Sulphur completely inhibited the fungus at 300 mg ai kg-1 . D. brochopaga showed tolerance to propiconazole up to 300 mg ai kg-1 but the fungus was completely inhibited at 400 mg ai kg-1 .The result of the present study indicate that D. brochopaga is sensitive to most of the fungicides tested under the present study. The fungus showed tolerance to Metalaxyl, propiconazole and Sulphur below 200 mg/µl ai kg-1 concentration of in soil.en_US
