Evaluation of Some Selected Options for Managing Brinjal Shoot and Fruit Borer in Two Intensive Brinjal Growing Areas

Abstract: The efficacy of 5 selected insecticides, two resistant lines and female sex pheromone against Brinjal shoot and fruit borer (BSFB) (Leucinodes orbonalis Guenee) were evaluated in Gazipur and Jessore of Bangladesh during May to October, 2007. The treatments comprised T = Cultivation of resistant line1 ISD006 without any insecticide use; T = Cultivation of resistant line BL114 without any insecticide use;2 T = Cultivation of susceptible variety Uttara without any insecticide use; T = Use of female sex Pheromone3 4 placed at canopy and in the center of the plot without any insecticide use; T = Spray Abamectin ® 1005 WSC @ 2 ml a.i. per litre of water; T = Spray Nimbicidin ® @ 4 ml L of water; T = Spray Suntap ® 50 SP @6 71 5 mg L of water; T = Spray Marshal ® 20 EC @ 1.5 ml L of water; T = Spray Ripcord ® 10 EC @ 1 ml L of1 1 18 9 water and T = Untreated control. The effectiveness of the treatments in reducing shoot and fruit infestation10 by the BSFB did not differ significantly between the different locations, the shoot and fruit infestation was recorded at 19.90 % and 16.16 % respectively, which was 20.88 % and 15.08 % in Jessore. However, the effectiveness of the options in reducing the shoot and fruit infestation differed significantly with different treatments and all treatments except T (the variety Uttara) significantly reduced shoot and fruit infestation over3 the control. Marshal 20 EC @ 1.5 ml L (T) performed the best ensuring the lowest shoot and fruit infestation1 8 (7.59 % and 4.16 % respectively) rendering 78.37 % reduction in shoot and 88.06 % and 88.99 % reduction in frui
