Comparison with botanicals and the bio-agents on Fruit borer, Helicoverpa armigera (Hubner) in Tomato

Abstract

The present investigation was conducted to study “Comparison with botanicals and the bio-agents on Fruit borer, Helicoverpa armigera (Hubner) in Tomato” was carried out during the Rabi season of 2019-20 at the central field of the Department of Entomology, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. The study revealed that the overall efficacy of botanicals and bio-agents from the two sprays revealed that treatment Spinosad 45% SC was the best treatment which recorded a minimum (9.75%) mean fruit infestation and was significantly superior over all other treatments. It was followed by Bacillus turingiensis, which recorded (12.03%) fruit infestation. The following treatments in descending order of effectiveness were Ha-NPV, Neem seed kernel extract, Beauveria bassiana, Tobacco leaf extract and karanj oil which were recorded (12.29%), (14.26%), (14.71%), (15.16%) and (15.58%) fruit infestation, respectively. All the above treatments were found to be superior to the control, which recorded maximum fruit infestation (24.46%). In Spinosad, 45% SC (245q/ha), Fruit yields were high followed by Bacillus turingiensis (220q/ha).
