Abstract
An experiment was conducted during the period of December 2014 to March, 2015 in the Entomology Field Laboratory, Department of Entomology, Bangladesh Agricultural University, Mymensingh on the management of tomato fruit borer, Helicoverpa armigera (Hubner) using different biorational insecticides on winter tomato variety BARI-2 in Bangladesh. Efficacy of seven different biorational insecticides viz. Neem oil, Mahogany oil, Karanja oil, Ambush 1.8EC, Libsen 45SC, Emamectin benzoate 5SG and Beauveria bassiana were evaluated on the basis of percentage of fruit damage and percentage increase/decrease of yield. All the biorational insecticides were significantly effective in comparison to control treatment. Besides, among seven insecticides; Emamectin benzoate 5SG provided the best result with the lowest cumulative mean percentage fruit infestation (20.95 % & 17.24% based on number & weight, respectively). Percentage reduction of infested fruit was the highest (57.50 & 62.38%, by no. and weight, respectively) in Emamectin treated plots. Similarly the highest percentage protection (58.99 & 63.06% by no. and weight, respectively) of infested fruit was also found from the Emamectin benzoate treatment. But Libsen 45SC revealed the highest efficacy on marketable fruit yield (20.23tonha-1) compared to other treatments. So, Emamectin benzoate and Libsen both might be used to manage tomato fruit borer effectively. [Fundam Appl Agric 2019; 4(2.000): 792-797]
