Abstract

Field studies were conducted for the determination of efficacy of different carbamate pesticides against spotted bollworm on okra crop at the agriculture and agribusiness department, university of Karachi. Seeds of okra crop were planted in March 2011 in a complete randomized block design along with 3 replicates. The crop was sprayed four times during the experimental period with a time interval of seven days. The results revealed that both the tested pesticides reduced the population of spotted bollworm as compared to the untreated control plot. The data indicated that the Dimehypo provided the best results followed by Monomehypo in reduction of the pest population. It may be concluded that the carbamate pesticides including dimehypo and monomehypo were effective for controlling the spotted bollworm population damaging the okra and causing minimum losses to pollinators, predators and other non targeted beneficial insects. Moreover, still better results could be obtained by applying these systemic pesticides in combination with the contact foliar pesticides.
