BIORATIONAL MANAGEMENT OF LEUCINODES ORBONALIS L. ON BRINJAL
A field experiment was conducted in the insectary premises, College of Agriculture, Nagpur, during kharif season of 2010-11 to the biorational management of brinjal fruit and shoots borer, Leucinodes orbonalis Guen. During the investigation, it was revealed that lowest infestation (shoot and fruit infestation) and highest yield over control was observed in the treatment spraying of spinosad 45SC @ 0.01% (256.71 q/ha) followed by the treatment spraying of cypermethrin 25EC @ 0.0075%, clipping of shoot + NSE 5%, spraying of NSE 5%, release of T. chilonis @ 7.5 cc eggs/ha; release of T. chilonis @ 6 cc eggs/ha; release of T. chilonis @ 5 cc eggs/ha; release of C. carnea; spraying of M. anisopliae @ 1 L/ha; clipping of shoot from initiation of infestation. The ICBR was highest in the treatment cypermethrin 25EC @ 0.0075% (i.e. 43.02). Among microbial, bio agent, botanical and insecticide, the treatment T. chilonis @ 7.5 cc eggs/ha shown promise in managing brinjal shoot and fruit borer and registered 25.46 ICBR next to cypermethrin treatment.
