Abstract

Population dynamics of aphids (Myzus persicae) and its management through biological means was studied on important brassicas viz., broccoli, cauliflower, turnip, knol-khol and radish during 2016 and 2017. Results revealed considerable reduction in aphids at 3rd, 5th and 7th days after spray of the NSKE in all the crops. However, significant reduction (> 85%) was observed after 7th day of spray, particularly in the treatments having vermicompost.
