Abstract

The field experiment was conducted during Rabi, 2019–20 to assess the bio-efficacy of some insecticides against diamondback moth of cauliflower, based on per cent reduction of larval population at different intervals, yield of cauliflower curds and benefit cost ratio. Total three sprays of insecticides were applied during the season. The pre-treatment larval population of diamondback moth was recorded one day before treatment and the post treatment population was recorded in all the sprays after 1, 3,5, 7 and 10 days of spraying of insecticides during the year.
