dc.description.abstractAbstract : The present investigation entitled, “EFFICACY OF INSECTICIDES AGAINST MAJOR PESTS OF SOYBEAN (GLYCINE MAX)” was conducted in kharif season 2020-21, at. Post Loha Tq. Loha, Dis. Nanded in the farm of Mr. Govind Vitthal Wasmatkare, survey no. 164 as per the Decision of BOS, Department of Entomology, Dr. PDKV, Akola. The experiment was laid in Randomize Block Design with seven treatments replicated thrice. The treatments included were Spinetoram 11.7 % SC @ 9 ml/10L, Lambda-cyhalothrin 4.9 % CS @ 6 ml/10L, Flubendiamide 39.35 % SC @ 3 ml/10L, Dichlorovos 76.00 % EC @ 6 ml/10L, Profenofos 50 % EC @ 20 ml/10L, Triazophos 40 % EC @ 13 ml/10L and control (untreated plot). Three treatments sprays were applied at 15 days interval to study the Efficacy of Insecticides against Major Pests of Soybean. Total three sprays of the above treatments were done at an interval of 15 days commencing first application at 30 days after sowing. The treatment Triazophos 40 EC @ 1.6 ml/L, Lambda-cyhalothrin 4.9 % CS @ 6 ml/10L, Profenofos 50 % EC @ 20 ml/10L was found significantly superior in recording lower percent infestation of girdle beetle and stemfly at par with each other. The next effective treatment was Flubendiamide 39.35 % SC @ 3 ml/10L followed by Dichlorovos 76.00 % EC @ 6 ml/10L and Spinetoram 11.7 % SC @ 9 ml/10L. The treatment Spinetoram 11.7 % SC @ 9 ml/10L, Flubendiamide 39.35 % SC @ 3 ml/10L and Lambda-cyhalothrin 4.9 % CS @ 6 ml/10L were found significantly in recording lower larvae/mrl semilooper and Spodoptera litura. And next effective treatment was Profenofos 50 % EC @ 20 ml/10L followed by Triazophos 40 % EC @ 13 ml/10L and Dichlorovos 76.00 % EC @ 6 ml/10L. Deleterious effect of treatments of insecticide was not observed on predators on soybean throughout the season all treatments were uniform population and effective in conservation of the natural enemies. Yield and incremental cost:benefit ratio of different insecticides used against major pests of soybean showed the Highest grain yield of soybean was recorded in Triazophos 40 % EC @ 13 ml/10L (19.69 q/ha) followed by Profenofos 50 % EC @ 20 ml/10L (18.86 q/ha), Lambda-cyhalothrin 4.9 % CS @ 6 ml/10L (17.89 q/ha), Flubendiamide 39.35 SC (17.38 q/ha) and Spinetoram 11.7 % SC @ 9 ml/10L (15.17 q/ha). The highest ICBR was obtained in lambda cyhalothrin 4.9 CS (1:14.87), followed by Triazophos 40 % EC @ 13 ml/10L (1:11.96), Profenofos 50 % EC @ 20 ml/10L (1:8.44), Dichlorovos 76.00 % EC @ 6 ml/10L (1:6.49) and Flubendiamide 39.35 % SC @ 3 ml/10L (1:2.29).en_US
