Twelve phyto products and two forms of cow dung were evaluated during 2021-22 in the Entomology Research Laboratory, M S Swaminathan School of Agriculture, Centurion University of Technology and Management, Gajapati District of Odisha for their efficacy against Rhyzopertha dominica (F) in stored paddy. The experiment was laid out in a completely randomized design with each treatment replicated thrice. Individual treatments comprised 20 g disinfested paddy seeds treated with test products @ 5g/ kg seed separately and an untreated check and inoculated with 20 adults /treatment. All the treatments were effective in suppressing the R. dominica, with maximum adult mortality (92.1%) being in black pepper powder followed by custard apple seed powder (88.4%) at 28 days after release. The least population buildup (2 adults), grain damage (3.3%), and weight loss (2.7%) were observed with black pepper powder treated paddy at 120 days after storage.
