ABSTRACT

An experiment was carried out to evaluate the efficacy of some novel insecticides either alone or in combination at different doses against the sucking pests, White fly and Jassids infesting brinjal during 2012 at BCKV, Kalyani, Nadia, West Bengal, India. Field efficacy tests of different insecticidal treatments as evident from percent reduction in population over control indicated that the pesticide Thiamethoxam 25 WG @ 25g a.i./ha was found most effective both in cases of White fly and Jassids for registering population reduction. Followed by Sumiprempt 20 EC @ 150 g a.i./ha (Pyriproxyfen5% +Fenpropathrin 15%) and Pyriproxyfen 10 EC @ 200g a.i./ha The treatment Diafenthiuron 50WP 300g a.i./ha was worst performer for recording population reduction of White fly and Jassids to the extent of 43.53-51.88% and 47.83-67.53 respectively.
