Efficacy of Insecticides against Pod Fly (Melanagromyza obtusa) Infesting Pigeonpea

Efficacy of insecticides against pod fly (Melanagromyza obtusa Malloch) of pigeonpea was evaluated under field conditions. There were 9 treatments viz., T1: spinetoram 11.7% SC, T2: indoxacarb 14.5% SC, T3: chlorantraniliprole 18.5% SC, T4: lambda-cyhalothrin 5% EC, T5: fipronil 5% SC, T6: acetamiprid 20% SP, T7: emamectin benzoate 5% SG and T8: quinalphos 25% EC and T9: untreated control. Two sprays were applied at an interval of 15 days. The performance of each insecticide treatment was categorized on the basis of maggot population. The results revealed that, chlorantraniliprole 18.5% SC @ 0.3 ml/l water was superior treatment in terms of least average population of pod flies (0.95 maggots/plant) and at par to indoxacarb 14.5% SC @ 0.7 ml/l water and spinetoram 11.7% SC @ 0.5 ml/l water reported 0.98 and 1.05 maggots/plant, respectively.
