Abstract

The investigation of Efficacy of different insecticides on natural enemies in maize ecosystem. The field experiment was conducted on the field of progressive farmer Shree. Baburao Mhaske Domegoan, Taluka Ambad, Dist. Jalna under the guidance of research guide, college of agriculture Badnapur during kharif 2021. The work was carried out in Randomized Block Design with three replications and seven treatments. The net plot size and gross plot size was 3.0 m × 2.2 m and 4.2 m × 3 m respectively with maize crop variety Fourtuner. The studies conclude that the natural enemies for all insecticides were found to be relatively safe except Indoxacarb 15.8 EC (T4) for LBB, Chlorfluazuron 5.4 EC for predatory spider and Emamectin benzoate 5SG for predatory bug. To convince the farmer for layout experiment in already planted crop and to keep watch on the activities of pest and it's response to different treatments were the challenges. The entire research programmed monitored and guided by research guide besides all the inputs were provided by college of agriculture Badnapur and losses occurred in the plant population during layout and losses in the yield caused by untreated control were beared by farmer.
