Management of White Fly (Bemisia tabaci Genn.) by Different Bio-Pesticides on Red Okra Crop

The experiment was conducted in Kharif season 2023 at an organic research farm, Kargua Ji, Department of Entomology, Bundelkhand University Jhansi. The present investigation was worked out with nine treatments including control (untreated) in three replications, a total of 27 plots were designed under randomized block design against the white fly infestation on the okra crop. Three applications of treatments were carried out and observations were taken at 3 days, 7 days and 14 days after spraying of the treatments. All the treatments were found significantly effective over control to manage the population of the white fly, where Neem oil was found to be the most effective treatment that recorded a minimum population of 6.94 whiteflies per leaf as per NKSE recorded 9.94 white fly/plant and Karanj oil (10.91), where all Neembased product was found effective against white fly moreover among all microbial pesticides Beaveria bassiana found effective. Among all treatments maximum yield was obtained from Neem oil treated plots recorded at 161.36 Qt/hac as per with NSKE (155.87 Qt/hac) but the highest C:B ratio was recorded under NSKE(1:1.82) followed by Neem oil (1:1.77).
