Abstract
This study evaluated the laboratory and field efficacy of some biopesticides against the banana pseudostem weevil Odoiporus longicollis (Olivier). Sprays were applied five times from 3rd to 11th month at 45 days intervals. The observations such as the oviposition marks, larval galleries, plant death and yield revealed 100% mortality in Avaya and chlorpyriphos and 91.66% in CTCRI-Nanma and neem based product Nimbicidine treatments. The field observations indicated that Nimbicidine and cassava based Nanma significantly reduced the infestation similar to positive control chlorpyriphos, and these were considered under 1st category. The botanicals Zimmu plant extract, gallic acid and Aavya (2nd category) and pongamia and neem soap (3rd category) provided moderate/less protection. It is concluded that the neem based botanical formulations could be effective and safe to use in banana against stem we evil.
