Abstract:

An experiment was conducted on the efficacy of selective insecticides and screening of germ plasm against gram pod borer of cow pea (Vigna unguiculata L.) under randomized block design at student farm, university of Agricultural sciences, Bengaluru during rabi, 2016-17. The objective of this study was to investigate the most effective insecticide and germ plasm against the pod borer population. Different groups of chemicals were selected and the treatments were imposed as foliar sprays by using a hand compression knapsack sprayer of about 500 lit ha-1 spray fluid against major insect pests. A field study was conducted to evaluate the efficacy of six insecticides viz., (Buprofezin 25 SC @ 250 g a.i./ha, Profenophos 50 EC @ 500 g a.i./ha, Azardirachtin 300 ppm @ 0.03% Imidacloprid 17.8 SL @ 25 g a.i./ha, Quinalphos 25 EC @ 250 g a.i./ha, Chlorpyrifos 20 EC @ 200 g a.i./ha.) against gram pod borer (Helicoverpa armigera H.) on Cowpea (Vigna unguiculata L.) variety KM - 5. The highest mortality of gram pod borer was recorded in plots treated with Quinolphos (85%, 90% and 94%) and profenofos (85%, 90% and 92%) at 3, 5 and 7 days after treatment (DAT), respectively. No plant mortality was recorded in untreated plots from 3 to 7 DAT. Thus, these insecticides proved highly effective for the management of gram pod borer on cowpea under field conditions and different genotypes against pod borer screened, in that PGCP – 3 have shown highly resistant to pod borer.
