Field efficacy of different insecticides against the pink pod borer, Cydia ptychora (Meyrick) on greengram.

摘要

A field experiment was conducted to determine the efficacy of nine insecticides against pink pod borer, Cydia ptychora (Meyrick) infesting greengram at the Junagadh Agricultural University campus, Junagadh during kharif season of 2008. The results revealed that spinosad 0.009%, indoxacarb 0.0075%, cypermethrin 0.009% or profenophos 0.05% were found the most effective in reducing pink pod borer population. Maximum yield and net realization was obtained in indoxacarb 0.0075%, spinosad 0.009%, cypermethrin 0.009% and profenophos 0.05%. The highest cost benefit ratio (1:15.29) was obtained in the treatment of cypermethrin 0.009%, followed by profenophos 0.05% (1:12.54), indoxacarb 0.0075% (1:7.54), monocrotophos 0.04% (7.19), quinalphos 0.05% (1:6.23) and spinosad 0.009% (1:5.55). Thus, indoxacarb, cypermethrin, spinosad and profenophos can be recommended for effective and economic management of pink pod borer infesting greengram.
