Abstract
Among the various treatments evaluated for their bio-rational effect against mustard aphid on Indian mustard during year- 2021-22 at C. S. Azad University of Agriculture & Technology Kanpur Uttar Pradesh, the descending order are the followed treatments are NSKE @10% > NSKE @5% > Cow Urine @ 10% > Verticillium lecanii @ 1.5kg/ha. > Lantana leaf extract @ 10 % > Castor leaf extract @ 10% > Lantana leaf extract @ 5 % > Castor leaf extract @ 5% > Cow Urine @ 5%. India, the spray of NSKE 10% @ 60 lit/ha followed by NSKE 5 % @ 30 lit/ha was proved to be the best treatments with pooled mean aphid population of 5.42, 5.10, 4.96, 4.85, 5.39, 5.26, 5.42, 5.23, 5.13, and 7.29 aphid/pant in the control after 1, 3, 5 and 7 days of treatment, respectively. The treatment NSKE 10 % was proved best and significantly superior over all treatments with highest reduction of Infestation of Lipaphis erysimi kalt. in both the years.
