Role of Panchgavya in the management of major soil borne fungal diseases of vegetable crops

摘要

Role of Panchgavya, an ancient preparation, was evaluated in the management of damping-off (Rhizoctonia solani), root rot (Fusarium solani) and collar rot (Sclerotium rolfsii), all soil borne fungal diseases. Seed dip in Panchgavya for different durations except > 2 hjrdid not suppress germination and results were comparable to Bavistin (0.25%) treated seed. Seeds coated with dried cow pat powder (5 g / kg) or with cow pat ash (2 g / kg) or dipped in cow dung slurry (1:1 v/v) for different durations,germinated equally well and results were comparable / superior to seed treatment with Bavistin (0.25%). Seeds treated with Panchgavya or any preparation of cow dung, hastened the germination and seedling possessed better vigour than those of untreated and Bavistin treated seeds. Seed dip in Panchgavya for 2 hr and sowing of untreated seeds in sick soil drenched 48 hr before sowing with Panchgavya, provided a very good control of damping-off of seedlings in cauliflower and okra. Seed dip in cow dung slurry (1:1) for 2 hr before sowing supported very good seed germination and was found most effective in controlling post emergence damping-off of seedlings in okra. Seed treatment with Bavistin coupled with soil drench with Panchgavya provided very good control of post-emergence damping-off of seedlings in cauliflower and okra and root rot of pea. Seedling dip in Captan @ 0.25% /Raxil @ 0.05% before transplanting coupled with soil drench with Panchgavya 24 hr after transplanting and subsequently at 1 and2 weeks interval, gave 94.8 per cent control of collar rot of tomato.
