Effect of various modules against Aphid, Aphis gossypii (Glover) on Okra

Abstract

Field studies were undertaken on “Evaluation of various modules against major pests of okra” during Summer 2014-15 and Kharif 2015-16 on the field of Chilli and Vegetable Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS.).An experiment was laid in randomized block design consisting of eight modules viz., M1 (fully organic), M2, M3 and M4 (Chemical module with sequential use of insecticides), M5, M6 and M7 (IPM based module having ST, Soil application, YST and sequential use of chemical insecticides) and untreated module M8 to find out effective modules against aphid on okra. The results revealed that module M7 (ST, SA, YST, Cyper+Dim., Fenpo, Ethion+Quin and Lamb.) was found statistically superior over all other treatments in recording the lowest aphid population (3.57/leaf) and significantly most effective in minimizing the population of aphids at 3,7 and 14 days after spraying. Next effective modules M5, M6 and M3 in second order of merit were found statistically equal among themselves. Module M2 was found least effective in minimizing the aphid population.
