Abstract
The purpose of this study was to evaluate efficiency of certain biological control agents for the ecologically sound and sustainable management of okra shoot and fruit borer (OSFB) at the Sher-e-Bangla Agricultural University, Dhaka. Randomized Complete Block Design (RCBD) with three replications was used for this experiment. It consists of seven different types of treatments, including as application of Trichogramma evanescence @5 Tricho cards/plots (T1), Trichogramma evanescence @0.08 g/plot (T2), Bracon hebetor @10 adults (Male:Female = 4:6) per plot (T3) while applying Bracon hebetor @15 adults (Male:Female = 6:4)/plot (T4). Applying Bacillus thuringiensis Serovar kurstaki @2ml suspension/liter water/4plot in T5 and Bacillus thuringiensis Serovar kurstaki @1ml suspension/liter water/plot in T6. T7 stands for untreated control in this study. All the treatments were applied at 7 days intervals. The best performance was obtained from treatment (T5) in reducing the shoot and fruit infestation (56.88 and 71.86%, respectively) by number and weight over control. The maximum total fruit yield (6544 kg/ha), i.e., 71.30% increase over control of okra, was produced in T5. So, from the present study, it may be revealed that bio-control agents can be used for the ecologically sound and sustainable management of okra shoot and fruit borer. Bacillus thuringiensis Serovar kurstaki may be used in this regard and the optimum dose may be 2ml suspension/liter water/plot and 7 days application interval should be followed.
Key Words: Bio-control agents, Eco-friendly management, Okra shoot and fruit borer, Food safety and Organic vegetable
