Abstract

The present investigation  were conducted at  department of Entomology SHUATS, Prayagraj during 2021-2022 using completely randomized design with three replications and treatments neem leaf powder, turmeric rhizome powder, clove powder, pepper powder, mustard oil, soybean oil and groundnut oil. Among the selected oils and botanicals treated to wheat grains, mustard oil and soybean oil were found to be highly effective in increasing adult mortality (100 %) and reducing the per cent weight loss (0.00%) in stored wheat grains. Turmeric rhizome powder was found to be least effective among all the treatments. The maximum germination percentage, vigour index 1 and vigour index 2 was  observed in grains treated with mustard oil (90%, 2250.00, 123.00) respectively on wheat grains. Turmeric rhizome powder was found to be least effective among all the treatments.
