Abstract
The field experiment was undertaken at the Experimental Farm, Department of Entomology, School of Agricultural Sciences (SAS), Medziphema Campus, Nagaland University, during the period of November 2021 to February 2022 to study the efficacy of certain bio-pesticides against major insect pests of broccoli. The experiment was conducted using Randomized Block Design (RBD) with six treatments including control and replicated four times. The study revealed that Indian cabbage white, Pieris spp. and green peach aphid, Myzus persicae have been found to be the major insect pest in broccoli. It is recorded that the highest (73.49%) population reduction of M. persicae was obtained from the plot treated with emamectin benzoate 5% SG and the highest (90.16%) population reduction of Pieris spp. was recorded on the plot treated with spinosad 45% SG. Therefore, the study concluded that use of bio-pesticides offers a great efficacy in controlling the pest and diminish the pesticides related issue.
