Title: Comparative Efficacy of Insecticiedes, Bio-pesticides and Botanicals against Leucinodes orbonalis Guenee infesting Brinjal
Abstract: The insecticides endosulfan, malathion and quinalphos proved most effective in reducing shoot infestation by 90.0, 87.5 and 80.0%, respectively. Among botanicals, neemarin and achook were significantly on par and effective by 78.5 and 77.6% followed by bioneem 69.6%, respectively in reducing shoot infestation over control. Bio-pesticides, however, register 60.8% and 59.6% reduction in shoot infestation in case of dipel and diolep, respectively. The maximum fresh fruit yield (21.778 t/ha) was obtained in endosulfan treated plot followed by malathion (19.222 t/ha) and quinalphos (17.722 t/ha) The fruit yield losses in case of endosulfan and malathion were (4.4%) and (5.5%) followed by quinalphos (6.9%). Neemarin and achook were significantly on par and registered 9.2 and 10.6% yield loss, respectively followed by bioneem 14.6%.
