EFFECTIVENESS OF SOME INSECTICIDES AGAINST MAJOR SUCKING PESTS OF OKRA (Abelmoschus esculentus L.)

Abstract

The experiment was conducted to study the effectiveness of some insecticides against major sucking pests of okra. The experiment consisted of 8 management practices. Incidence of major sucking insect pests of okra was recorded for the entire cropping season; and the insect pests were Jassid, white fly and aphid, respectively was observed. At total fruiting stage, in number basis, considering the % fruit infestation, the lowest infested fruits per plant in number were recorded from Admire 200 SL @ 0.5 ml/L of water (2.66%), while the highest infested fruits were recorded in control (18.99%). In weight basis % fruit infestation was found from Admire 200 SL @ 0.5 ml/L of water (2.46%), whereas the highest infested fruits were recorded in control (16.88%). The tallest plant was recorded from Admire 200 SL @ 0.5 ml/L of water (227.62 cm), while the shortest plant was found from control (190.96 cm). The longest fruit was observed from Admire 200 SL @ 0.5 ml/L of water (18.69 cm) again the shortest fruit was recorded from control (15.45 cm). The maximum number of fruits per plant was obtained from Admire 200 SL @ 0.5 ml/L of water (32.60) and the minimum number of fruits per plant was found from control (28.20). The highest yield of fruits was observed from Admire 200 SL @ 0.5 ml/L of water (15.94 ton/ha), while the lowest yield per hectare was found from control (11.64 ton). Considering the controlling of okra sucking pest highest benefit cost ratio (2.91) was recorded in the treatment Admire 200 SL @ 0.5 ml/L of water and the lowest benefit cost ratio was recorded from Shobicron 425 EC@ 2 ml/L of water (1.15).
