Effectiveness of Some Potential Insecticides for Controlling Eggplant Shoot and Fruit Borer in Bangladesh

Abstract

ABSTRACT The experiment was conducted in the central farm of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka, Bangladesh during February to September, 2013 to evaluate some potential insecticides in comparison with conventional insecticides for controlling eggplant shoot and fruit borer (ESFB), Leucinodes orbonalis. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and six treatments applied at 7 days interval. The treatments were T 1 [Acimix 55 EC (Chlorpyrifos 50% + 5% Cypermethrin) at the rate of 1 ml/L of water]; T 2 [Calypso (Thiacloprid) at the rate of 1 ml/L of water]; T 3 [Neem oil at the rate of 3 ml/L of water]; T 4 [Neem Seed Karnel Extract at the rate of 100 g/L of water]; T 5 [Nexaid (Gamma-cyhalothrin) at the rate of 1.5 ml/L of water]; T 6 (Untreated Control). The results revealed that amongst different treatments Acimix 55 EC was most effective in reducing shoot infestation (66.72%) and Calypso was found most effective in reducing fruit infestation over control by number Original Research Article
