Abstract

Experiment was carried out in the farmer’s field at Sonakhali, Barguna sadar, Barguna district of Bangladesh during January to April 2018 to evaluate the effectiveness of different IPM packages against pod borer complex of mungbean. Results revealed that the lowest number of pod borer (1.33/m2), the highest percent (93.56%) pod borer reduction over control, lowest pod damaged (5.33/m2), highest percent (87.70%) pod damaged reduction over control at 65 DAS were recorded in Package 5 (Bioneem plus 1% EC @ 1 mL/l of water + sex pheromone trap) treated plots. The highest yield (1,416 kg/ha), percent yield increase over control (40.26%), highest net return come (Tk. 23,146/ha) and highest marginal benefit cost ratio (4.35) were obtained from Package 3 (Sex pheromone trap + white sticky trap) treated plots followed by Package 5 (1,319 kg/ha and 27.33%) and the lowest yield (1,010 kg/ha) from untreated control. From this experiment Package 3 (Sex pheromone trap + White sticky trap) was found to be the best integrated management package for the suppression of pod borer complex and produced maximum yield of mungbean. Integration of IPM components revealed that installation of sex pheromone trap along with white sticky trap (package 3) was found to be the best IPM package for the management pod borer complex producing maximum yield and providing highest marginal benefit cost ratio of mungbean.
