The experiment was conducted in Rabi 2023 at Organic Research Farm, under Department of Entomology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi to evaluate the efficacy of bio-pesticides and botanicals against the infestation of diamondback moth (Plutella xylostella L.) in cauliflower. Nine treatments included control (Untreted) were used in 9 plots with 3 replications, all the treatments were sprayed in three times and data collected at 3 days, 7 days and 14 days after applications. The investigation resulted all the treatments were found significantly effective over control. The minimum larval population of DBM was recorded under Bacillus thuringiensis @ 1.5 kg/hac as per with Beauveria bassiana @ 1.5 kg/hac and Neem oil 2% and Metarhizium anisopliae@ 1.5 kg/hac also give similar result as neem oil. The highest crop yield and C:B ratio was obtained under Bacillus thuringiensis @ 1.5 kg/hac (210.89 and 1:3.94) as per with Beauveria bassiana @ 1.5 kg/hac (190.65 and 1:3.48).
