Abstracts

The experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from October 2015 to March 2016 aiming to develop an IPM package based on effective insecticides and bio-pesticides against tomato fruit borer (Helicoverpa armigera, Lepidoptera: Noctuidae). Tomato variety BARI tomato-14 was used as planting material. The experiment consisted of six treatments as- T1: Mechanical control, T2: Voliam Flexi 300 SC @ 0.5 ml/l of water at 7 days interval + Pheromone trap at 10 m2 distance, T3: Voliam Flexi 300 SC @ 0.5 ml/l of water + Bioneem plus 1EC (Azadiractin) @1 ml/l of water at 7 days interval, T4:  Bioneem plus 1EC (Azadiractin) @1 ml/l of water + Spinosad 45 SC @ 4 ml/10l of water (bio-pesticides) + Pheromone trap at 10 m2 distance, T5: Mechanical control + Voliam Flexi 300 SC @ 0.5 ml/l of water + Bioneem plus 1EC (Azadiractin) @1 ml/l + Pheromone trap at 10 m2 distance and T6: Untreated control. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. At the total fruiting and ripening stage, the minimum number of fruit borer larvae per plant (0.73 and 1.00, respectively) was recorded from T5, while the maximum number of fruit borer larvae per plant (9.47 and 13.07, respectively) was found from T6. At entire ripening stage of tomato in number basis, the lowest percentage of infested fruits per plant in number basis (2.11%) was found in T5, while the highest percentage of infested fruits in number basis (11.55%) was found in T6 treatment. At entire ripening stage of tomato in weight basis, the lowest percentage of infested fruits per plant in weight basis (1.97%) was found in T5, while the highest percentage of infested fruits in weight basis (10.20%) was observed in T6. The highest fruit yield (59.82 t/ha) was found in T5, whereas the lowest fruit yield (50.36 t/ha) was recorded in T6 treatment. The highest benefit-cost ratio (2.11) was estimated for T5 treatment and the lowest (0.15) for T1 treatment under the trial. It is observed that Mechanical control + Voliam Flexi 300 SC @ 0.5 ml/l of water + Bioneem plus 1EC (Azadiractin) @1 ml/l + Pheromone trap at 10 m2 distance was more effective against the fruit borer of yield attributes and yield of tomato.
