Abstract

The experiment was conducted to evaluate relative efficacy of synthetic insecticides against sucking insect pests of chilli crop at Bozdar Agriculture Farm, Distrcict Tando Allahayar during-2015. The chilli variety Advanta-509 was sown and treated with insecticides T1= Deligate (Spinetoram) 25 water dispersible granule (WG) 4 mg/1lit water, T2= Novastar (Bifenthrin + Abamectin) 11.5 emulsifiable concentrate (EC) 5ml/1lit. Water and T3 = Transfarmer (Sulfoxaflor) 50 WG 3 mg /1 lit water of water at 1 DAS, 4 DAS, 7 DAS and 10 DAS (Days after Spray) intervals in each treatment. The results indicated that spinetoram and bifenthrin + abamectin insecticides was found best for reduction in thrip per leaf and flower population as compare to sulfoxaflor insecticides. The result further revealed that a bifenthrin + abamectine insecticide was found more excellent for whiteflies reduction in population followed by spinetoram and sulfoxaflor insecticides. Similarly, a sulfoxaflor insecticide was declared more excellent for management of aphid in chilli crop followed by bifenthrin + abamectin and spinetoram insecticides. The highest average yield was obtained plot treated with insecticide sulfoxaflor followed by insecticides Bifenthrin + Abamectine, spinetoram and control (Untreated), respectively. The analysis of variance of results indicated that there is no significant (P<0.05) difference in yield obtained from plot treated with insecticide, however, the control (untreated) plot significantly (P<0.05) different than insecicide.
