Experiments were conducted to find out the seasonal abundance of insect pests on mungbean at Agricultural Research Farm of Banaras Hindu University during two season namely Kharif 2010-11 and 2011-12. The data of seasonal abundance of insect pests was correlated with weather factors prevailing during the experimental period and age of the crop. Efforts were also made to evolve most effective and economical control of whitefly, jassids and spotted pod borer attacking the crop. During Kharif 2011-12, the lowest pod damage per cent recorded in spinosad (2.33 per cent) followed by indoxacarb (2.67 per cent) and Bt (3.33 per cent). The highest pod damage recorded in acetamiprid (6.33 per cent). The lowest seed damage per cent recorded in spinosad (1.33 per cent) followed by thiodicarb (1.67 per cent), indoxacarb (2.00 per cent), Bt (2.00 per cent), endosulfan (2.33 per cent) and profenophos (2.33 per cent). The maximum yield recorded in indoxacarb (11.67 q/ha) followed spinosad (11.32 q/ha) and thiodicarb (11.18q/ha). The lowest yield was recorded in azadirachtin (9.93 q/ha) during Kharif, 2010-11. During Kharif, 2011-12, the maximum yield recorded in indoxacarb (12.04 q/ha) followed by spinosad (10.93 q/ha), profenophos (10.93 q/ha) and thiodicarb (10.65 q/ha) while lowest yield in azadirachtin (9.44 q/ha) treated plots. During Kharif, 2010-11, the highest cost: benefit ratio was obtained from the plot which was sprayed with acetamiprid (1:9.77) followed by lamda cyhalothrin (1:7.62), thiodicarb (1:5.64) and endosulfan (1: 5.26). The lowest cost: benefit ratio was obtained from the spinosad (1:1.82) treated plot. The highest cost: benefit ratio was obtained in plot receiving with acetamiprid (1:7.97) and was closely followed by lamda cyhalothrin (1:7.61). The lowest cost: benefit ratio was obtained in spinosad (1:2.13) during Kharif, 2011-12. |
