Different methods such as mechanical, biological and botanical were adopted singly as well as in combination to manage mustard aphid. The mustard aphid was regularly monitored during crop season to give treatments for management of mustard aphid on need basis. The application of treatments was done on the basis of ETL i.e. 25 aphids 10 cm−1 central twig plant−1. All the treatments were effective in controlling mustard aphid. The chemical control with oxydemeton methyl 25 EC @ 0.05% was found as the most effective resulting in significantly higher yield as compare to other treatments. The treatments comprising mechanical+botanical+biological control were found to be the best alternative to chemical control for management of mustard aphid.
