Abstract:
Investigations on biology of groundnut leaf weevil, Cyrtozemia dispar Pascoe were carried out at Instructional farm, College of Agriculture, Junagadh Agricultural University, Junagadh during Kharif, 2018. For the management of leaf weevil, different combinations of soil application and foliar application of insecticides were evaluated. Among the different insecticide combinations, leaf weevil can be effectively managed by soil application of carbofuran 3G @ 1 kg a.i./ha at 30 DAS + foliar application of chlorpyriphos 20 EC @ 0.04% followed by carbofuran 3G @1 kg a.i./ha at 30 DAS + acephate 75 SP @ 0.075%. Carbofuran 3G @ 1 kg a.i./ha at 30 DAS + control and carbofuran 3G @ 1 kg a.i./ha at the time of sowing + control combinations performed less in giving satisfactory protection to groundnut crop against leaf weevil. The highest (2238.00 kg /ha) pod yield harvested in the plots treated with carbofuran 3G @ 1 kg a.i./ha at 30 DAS + chlorpyriphos 20 EC @ 0.04% followed by carbofuran 3G @ 1 kg a.i./ha at 30 DAS + acephate 75 SP @ 0.075% (2102.00 kg /ha).
