- Abstract
The field experiment was conducted during 2020 in Bagalkot district in Karnataka, India to know the effective chemical molecules for managing the grape mealybug. Among the bio-rationals and insecticides tested, buprofezin 25 SC @ 1.25 ml/l, fish oil rosin soap (Meenark®) @ 5 ml/l, flonicamid 50 WG @ 0.3 g/l, dimethoate 30 EC @ 1.7 ml/l and chlorpyriphos 50 EC @ 2 ml/l were the promising insecticides in managing grape mealybug. Insecticides and bio-rationales used for field spray against grape mealybug among five insecticides, buprofezin 25 SC @ 1.25 ml/l gave a better yield than other treatments with 23.14 t/ha and highest net return of Rs. 8,23,240/-as compared to other treatment with BC ratio 9.04. The next best treatment was fish oil rosin soap (Meenark®) @ 5 ml/l with BC ratio of 8.94 followed by flonicamid 50 WG @ 0.3 g/l with BC ratio of 8.58. The lowest yield, net return, and BC ratio of 18.51 t/ha, Rs. 6,38,090/-and 7.30, respectively was observed in untreated control as compared to other treatments.
