15. Relative efficacy of synthetic insecticides against sucking insect pests of chilli crop

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.
