abstract
Study was conducted for nine years from 2006-07 to 2014-15 during kharif–rabi season to know the behavioral of web forming insect on red gram. Results revealed that incidence was ranged from 8.58 to 26.25 percent in the district with a highest incidence of 22.40 percent during 2010-11. Among the several insecticides tested, combination of profenophos 50%EC @ 2.00 ml/l + DDVP 76EC @0.50 ml/l was found to be the best treatment and recorded the minimum number of larvae (0.20/pl), pod damage (4.90%) as compared to the other insecticide treatments and untreated control (6.60 larvae/ plant & 38.10% of pod damage). The highest yield (11.14q/ha) and net profit (Rs.30382/ha) was also realized in Profenophos + DDVP treatment.
