A laboratory experiment was carried out to evaluate botanicals and locally available natural products against rice weevil Sitophilus oryzae (L). Phytolacca dodecandra (endod) seed, Azadirachta indica (neem) seed, and Allium sativum (garlic) led to more adult mortality as well as had a comparable effect to malathion dust (5%), which completely protected the grains against F1 progeny, while Croton macrostachyus leaf and seed powder caused the lowest adult mortality. However, P. dodecandra leaf and A. indica seeds led to the least amount of seed damage. The germination tests showed that none of the botanicals had an adverse effect.
