Efficacy of Different Neonicotinoids and Bio Pesticides on Okra Against Bemisia Tabaci

Abstract

The current study was investigated at the Agricultural Research Institute Tarnab, Peshawar during 2020 in a Randomized Complete Block Design (RCBD) with three replications. The study aimed was determining the efficacy of different neonicotinoids insecticides and bio- pesticides against Bemisia tabaci on okra crop. Results revealed that significantly maximum number of whitefly (Bemisia tabaci) population reduction was recorded in imidacloprid (7.55plant-1) treated plot followed by acetamiprid (8.88plant-1) and bio-pesticides (11.99 plant-1) while minimum population reduction was recorded in clothianidin (14.66 plant-1) treated plot over checked plot after 1st application while similar observation was recorded after the 2nd application. In terms of CB ratio, highest CB ratio was recorded by imidacloprid treated plot followed by bio pesticide, acetamiprid and clothianidin while lowest CB ratio was recorded by acetamiprid. Similarly, the research work concluded that overall best performed by imidacloprid after 1st and 2nd application while minimum control was observed by clothianidin treated plot over the control treatment.
