Abstract
During the Kharif season of 2022–2023 at Research Farm, Rajmata Vijyaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, Madhya Pradesh, a field experiment was carried out to assess the effectiveness of seven treatments: T1 - Dimethoate 30 EC (1000 ml); T2 - Imidachloprid 17.8 SL (125 ml); T3 - Acetamiprid 20 SP (125 gm); T4 - Flubendiamide 48 SC (500 ml); T5 – Emamectin benzoate 5 SG (100 gm); T6 – Fipronil 15% SC (2000 ml); and T7 - Un-treated. The observations were made three, seven, and fifteen days after the first and second pesticide sprayings, respectively. The data indicated that Imidachloprid 17.8 SL @ 125ml ha-1 was the most effective insecticide out of the six, and that it was better at controlling the incidence of sucking insects in cowpea, such as aphids (Aphis craccivora (Koch)), thrips (M. distalis (Karny)), whiteflies (A. rachipora (Singh)), and jassids (E. kerri (Pruthi)). However, it was found that Acetamiprid 20 SP was least successful in controlling sucking insects.
