ABSTRACT
The present investigation on was undertaken on the biorational management of brinjal shoot & fruit borer, Leucinodes orbonails Guen. in the insectary premises, College of Agriculture, Nagpur. Result showed that, lowest infestation of the borer and highest yield over control observed in descending order such as (T1) mechanical clipping of shoot at initiation of infestation followed by spraying of Carbaryl 0.2 %; (T5) mechanical clipping of shoots at initiation of infestation followed by release of T. chilonis @ 1.5 lakh eggs/ha; (T4) mechanical clipping of shoot at initiation of infestation followed by spraying of B. thuringiensis @ 1 lit/ha; (T3) mechanical clipping of shoot at initiation of infestation followed by spraying of M. anisopliae @ 1 lit/ha; (T2) mechanical clipping of shoots at initiation of infestation followed by spraying of B. bassiana @ 1 lit/ha and (T6) mechanical clipping of shoots alone from initiation of infestation. Incremental benefit cost ratio (IBCR) were observed in order of T5 > T6 > T1 > T3 > T4 > T2. The IBCR was highest in T5.
