Sixteen botanical products were tested for their efficacy to control mize weevil, Stophilus zeamais on stored sorghum seeds, under laboratory conditions. For comparison, three more treatments-primiphos methyl, malathion and untreated check were included and the experiment was replicated three times. Within 28 days after treatment, some botanical products caused 100 percent mortality of the weevil, which was comparable to the two synthetic insectivides. These were seed and leaf powder of Chenopodium ambrosioides, stem powder of Cissus rotundifolia, leaf powder of Jatropha curcas and seed powder of Phytolocca dodecandra. The botanicals, which caused over 50 percent cumulative mortality of the weevils at 14 days after treatments include, C. ambrososiodes (seed, leaf), J. curcas (leaf), P. dodecandra, C. rotundifolia (stem) and Maesa lanceolata (leaf). The effect of the promising botanical treatments on weevil progeny survival as well as on seed germination and seed weight loss are discussed.
