No egg hatching of P. brassicae was recorded at the highest concentration (5.0%) of petroleum ether and aqueous extracts of Parthenium. After 48 hrs of exposure of first instar of P. brassicae, 100% mortality was recorded at 2.5% and 5.0 concentration. Aqueous extract of Parthenium provided good control with 70.0% mortality of second instar of P. brassicae after 48 hrs of exposure. The petroleum ether extract and aqueous extract of Parthenium provided 50% and 60% mortality of first instar of S. litura, whereas 10% aqueous extract of P. hysterophorous recorded maximum % growth inhibition of Sclerotium rolfsii (59.5%). The compost prepared with E. fetida inoculum had high N, P, K content and low organic carbon and C/N ratio. Maximum (62.8%) recovery was recorded in Parthenium + cow dung + earthworm treatment.
