Abstract

A field trial was conducted to evaluate the efficacy of chemical and botanical insecticides against major insect pests of brinjal at the research farm of College of Agriculture and Research Station, Mahasamund, (C.G.) during rabi 2022-23. The experiment consisted of randomized block design with three replication and eight treatment viz., (T₁) Chlorantraniliprole 18.5%SC, (T₂) Emamectin benzoate 5%SG, (T₃) Spinosad 45%SC, (T₄) Bacillus thuringiensis 5%WP, (T₅) Azadiractin 5%EC, (T₆) Neem oil 2%, (T₇) NSKE 5% and (T₈)control (untreated). Results found that the lowest shoot infestation (12.92%), lowest fruit infestation by number (20.05%) and weight (24.63%), maximum fruit yield (183.53q/ha) were achieved by (T₃) spinosad 45%SC @187ml/ha^-1  compared to all other treatments.
