Efficacy of different insecticides against inflorescence thrips, Scirtothrips dorsalis Hood in mango

Abstract

Field experiments on effectiveness of different insecticides against inflorescence thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) in mango were carried out at Horticulture Farm, Junagadh Agricultural University, Junagadh, India during 2013-14 and 2014-15. All the treatments were significantly superior over untreated check. Results indicated that the maximum reduction of hopper population was recorded in the treatment of spinosad 45 SC (0.13%) and it was statistically at par with acetamiprid 20 SP (0.01%) and carbosulfan 25 EC (0.05%) after third and seventh day of first and second spray in both years. The highest population of thrips per inflorescence found in treatment flubendiamide 480 SC, 0.14% and chlorfenapyr 10 SC (0.0075%).
