The module components worked well resulting in low egg density, lower intensity of infestation and extent of damage and less quantity of pesticide to effectively suppress population build up of the next generations. The components worked in the way as was expected and two times application of synthetic chemicals (rynaxypyr 0.4 G @ 40 g ai/ha; cartap hydrochloride 4G @ 300 g ai/ha) in conjunction with neem oil (7 ml/l) in rational treatments provided good protection registering only 1.1-9.1% top borer infestation, 2.1-10.5% stalk borer infestation and 5.3-8.9% root borer infestation and sponsored good yields (73.7-75.6 t/ha). These treatments were statistically at par with chemical check, imidacloprid 0.3 GR @ 100 g ai/ha (three applications), which suffered 1.3-10.5% top borer infestation, 2.9-10.7% stalk borer infestation and 5.4-9.4% root borer infestation. Significantly high infestation was recorded in untreated check during peaks of top borer, stalk borer and root borer.

L. orbonalis causes broad-based problems in eggplant cultivation. An effort was made to control the borer during the Indian rainy season, as this is the time when the problem is at its worst. The impact of treatments on natural enemies as well as pollinators was also assessed. Integration of phytosanitation, mechanical control and prophylactic application of neem seed kernel extract (NSKE) exerted a satisfactory impact on the incidence and damage of L. orbonalis. After two need-based applications of new generation pesticide molecules like flubendiamide or rynaxypyr or emamectin benzoate, fairly good, healthy yields were produced. A ready-mix formulation (triazophos 40% + cypermethrin 4%), and carbofuran also offered good protection against the ...
