Efficacy of Biorational and eco-friendly control strategies in brinjal against Epilachna beetle, jassids and whiteflies

JR Mallick, S Dash and HP Patnaik

Field studies were undertaken during winter 2012-13 at Bhubaneswar (Odisha) to reveal the impact of indigenous products and bio-nutrients along with reduced levels of fertilizers on the incidence of insect pests of brinjal cv. Blue star. The jassid population was unaffected with nutrient levels tested, while application of 50% recommended dose of fertilizers (125:100:80 kg/ha of N, P and K) (RDF) with Bio-NPK showed significantly high population of whiteflies (3.65/3 leaves) as against 3.05/3 leaves in plot receiving RDF. The leaf damage by Epilachna beetle, fruit damage (both on number and weight basis) and marketable fruit yield were however, found unaffected by the nutrient sources tested. The benefit cost ratio was appreciable when the crop was raised with 50%RDF + Bio-NPK and protected with carbosulfan 25EC (3.44:1) and Spinosad 45SC (2.20:1).
