Effect of selective insecticides for management of brinjal shoot and fruit borer (Leucinods orbonalis Guenee)

Abstract

Brinjal (Solanum melongena L.) is a versatile vegetable. Among the solanaceous vegetables, brinjal is one of the most popular and economically important vegetables among small farmers and it is a source of income for resource-poor farmers. Shoot and fruit borer (BSFB) (Leucinodes orbonalis Guenee) is a serious insect pest in all brinjal growing states of India. Different insecticides were evaluated for management of shoot and fruit borer. An investigation was carried out using Soham variety of brinjal during 2018-19 at JNKVV, Krishi Vigyan Kendra, Chhindwara, Madhya Pradesh. Three different new molecules of Insecticides with different formulations were used viz. Spinosad 45 SC with (0.3 ml./l.) concentration, Flubendiamide 480SC with (0.25 ml/l) concentration and Emamectin benzoate 1.9 EC with concentration of (1.0 ml/l) sprayed at three different intervals. All infested fruits were picked from plots one day before insecticide application. Infected shoots were marked by tying a ribbon to all drooping shoots one day before spray. Fruit and shoot infestations were recorded seven days after insecticide application from plants. All treatments reduced shoot and fruit infestation significantly as compared to the control. However, the loss of brinjal was significantly reduced when the plots were treated with Spinosad (0.3 ml/l) proved to be the most effective insecticide followed by Emamectin benzoate (1.0 ml/l) Flubendiamide (0.25 ml/l) and Neem oil (5ml/l) treated plots had the least shoot infestation.
