Botanicals severely in the stored product pest management. The present investigation was carried out to identify the suitable alternative plant extracts. There were seven pesticidal plant species selected and their leaves or plant parts having pesticidal effects the target insect Sitophilus oryzae. The maximum mortality of S. oryzae was observed with sweet flag rhizome (3%) extract (100%) and custard apple leaf extract (96.6%). The maximum repellency was observed sweet flag rhizome extract (80.00%) followed by chillies dry fruit extract (76.66%). The maximum fumigant toxicity action increase in sweet flag rhizome extract (95.00%) at 72 h after treatment. The effect of plant extract on germination of seed was also observed by germination test.
