Eco-friendly management of pseudostem weevil, <i>Odoiporus longicollis </i>(Oliver) in banana

An investigation on environment friendly management against pseudostem weevil, [Odoiporus longicollis (Oliver)] in banana was carried out during year 2021-22 at farmers’ field in Siyod village of Surat district with ratoon crop and tissue culture plants. Though standard check and farmer practice were found effective, but among biopesticides and botanicals, stem injection with Azadirachtin 10000 ppm @ 4.0 ml l-1 was superior and minimized the plant damage, holes on pseudostem and pest population of pseudostem weevil as well as exhibited the higher fruit yield and incremental cost benefit ratio. After that, swabbing of Azadiractin 10000 ppm @ 2.5 ml l-1 and spraying of Beauveria bassiana (2 x 108 CFU g-1) @ 4.0 g l-1 + pseudostem trapping also proved their effectiveness than other treatments. These three treatments also exhibited higher plant height, pseudostem girth, hands per bunch and fingers per bunch than other biopesticides and botanicals. The ratoon crop plantation was found more susceptible than tissue culture plantation.
