A total of seven treatments of animal by-products which are used in the preparation of Panchgavya viz., Cow Urine, Cow Dung, Dung + Urine (1:1), Dung + Urine (2:1), Cow curd, Cow ghee and Cow milk were screened against the test pathogen at 5, 10, 15 and 20 per cent concentrations under Sterilized and Unsterilized conditions. Under sterilized set of experiment significantly maximum inhibition of the mycelial growth was obtained in cow-urine (76.35%) followed by cow-ghee (41.57%), cow-dung + cow-urine (1:1) (38.43%), cow-curd (35.29%), cow-dung (27.88%) and cow-dung + cow-urine (2:1) (16.67%). No sclerotia formation was observed in higher concentrations except in cow-curd. Whereas under unsterilized condition, cow-urine, cow-curd, cow-dung+ cow-urine (1:1) showed 100% inhibition followed by cow-dung + cow-urine (2:1) (85.69%), cow-dung (84.71%) and Cow ghee (19.02%). Cent percent inhibition of sclerotia production was observed in all treatments at all concentrations except under cow-milk treatment. Cow-milk was found at par with untreated check in inhibiting mycelial growth of
Rhizoctonia solani in sterilised as well as unsterilized experiment. For all treatments unsterilized set of experiment were found inhibiting much higher per cent mycelial growth of R. solani as compared to their sterilised counterparts.
