Effectiveness of Some Potential Insecticides for Controlling Eggplant Shoot and Fruit Borer in Bangladesh
Journal Title: Journal of Experimental Agriculture International - Year 2015, Vol 9, Issue 5
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 T1 [Acimix 55 EC (Chlorpyrifos 50% + 5% Cypermethrin) at the rate of 1 ml/L of water]; T2 [Calypso (Thiacloprid) at the rate of 1 ml/L of water]; T3 [Neem oil at the rate of 3 ml/L of water]; T4 [Neem Seed Karnel Extract at the rate of 100 g/L of water]; T5 [Nexaid (Gamma-cyhalothrin) at the rate of 1.5 ml/L of water]; T6 (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 (68.56%) and weight (61.04%). The best treatment, though, T1 and T2 reduced the highest level of shoot and fruit infestation respectively, they increased the maximum level of plant and fruit related yield attributes. T2 increased the maximum height, number of branches per plant, fruit length and girth, number of fruits per plant, and single fruit weight of eggplant over control followed by Acimix whereas Neem Seed Kernel Extract showed the least performance. Calypso also increased the highest fruit yield (15.36 t/ha) over control followed by Acimix (14.86 t/ha). So, Acimix 55 EC (Chlorpyrifos 50% + 5% Cypermethrin) and Calypso (Thiacloprid) may be suggested to the farmers for controlling Eggplant shoot and fruit borer (ESFB) at shoot and fruit infestation time respectively.
