Abstract:
The laboratory experiments were conducted to study the efficacy of some indigenous plant products such as sweet flag rhizome powder @ 5%, tobacco leaves powder @ 1%, clove powder @ 2%, ginger rhizome powder @ 2%, ajwain seed powder @ 2%, neem leaves powder @ 5%, turmeric rhizome powder @5% against rice weevil, Sitophilus oryzae (L.) on stored wheat by undertaking various parameters viz., percent adult mortality, percent seed damage and percent weight loss after three months of storage. The research was carried out at Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, U.P. in department of Entomology 2022-2023. This experiment was conducted under Complete Randomized block Design (CRD). After 90 days of storage for observation. among different plant products evaluated for their efficacy against rice weevil, Sitophilus oryzae for stored wheat grains, sweet flag rhizome powder was found significantly superior in reducing 100 percent adult mortality, no seed damage and no seed weight loss was found significantly superior followed by tobacco leaves powder, clove powder, neem leaves powder and ajwain seed powder. Whereas, the minimum efficacy was recorded in ginger rhizome powder and turmeric rhizome powder. The present study clearly revealed that these naturally occurring indigenous plant products could be used to manage the storage insect pests in wheat.
