abstract
A field experiment was conducted to determine the efficacy of ten chemical insecticides against spotted pod borer, Maruca vitrata (Geyer) infesting black gram. The results revealed that the least larval population was recorded in the treatment profenophos 50 EC + DDVP 76 EC (0.80 larvae/plant) followed by emamectin benzoate 5 SG + DDVP 76 EC (1.33 larvae/plant) and it was found on par with flubendiamide 480 SC + DDVP 76 EC (1.70 larvae/plant), spinosad 45 SC + DDVP 76 EC (1.83 larvae/plant) and thiodicarb 75 WP + DDVP 76 EC (1.83 larvae/plant). The treatment application of profenofos + DDVP @ 2ml + 0.5 ml per lit recorded lowest pod damage (7.13 per cent) and highest grain yield 9.20 (q/ha) in black gram. Thus, two sprays of profenophos 50 EC + DDVP 76 EC one at 50 % flowering and another at 15 days after first spray can be recommended to the farmers for management of spotted pod borer on black gram.
