Medicinal Plants & Cow’s excrement: An Estimable Wealth of Nature

Abstract
The present study aimed to determine inhibitory effect of Cow urine extract and hot water extract of four medicinal plants Viz. Bixa orellana, Vitix negundo, Putranjeeva roxburghii and Cryptolepis buchanani. Different parts of the plants were used to check their antimycotial efficacy against Sclerotium rolfsii Sacc., a common plant pathogen known as “Kudzu of the Fungal world”. This investigation comprises a comparative corroboration of cow urine extract and hot water extract of the selected medicinal plants by employing Poisoned Food technique. In-Vitro study reveals that out of the two solvents used cow urine extracts of plant parts were found to be more effective than the hot water extracts, which shows that Cow urine has immense antimycotial power to annihilate the pathogenic fungi. Out of the four selected plants  Bixa orellana  and Putranjeeva roxburghii’s cow urine leaf and root extracts has more potential to check the fungal growth over Cryptolepis buchanani and Vitix negundo leaf and root hot water  extract while comparing with Hexaconazole (100ppm) as standard.
