Abstract 

Bioactivity of botanical pesticide from weed was studied to find the most effective botanical pesticide for controlling Sitophilus spp. and maintaining the corn seed viability in storage. The research was a single factor experiment arranged in Completely Randomized Design. The experiment factor was kind and dose of botanical pesticide. The treatments of the experiment consisted of Ageratum conyzoides (goatweed) and Lantana camara (common lantana) in the doses of 2% ; 4% and 6 % respectively, and application without pesticide as a control. Botanical pesticide was in powder formulation. The reasearch consisted of two steps, the first was toxicity test of botanical pesticide in the storage for 70 days, and the second was seed viability test after storag for 70 days. The results showed that goatweed botanical pesticide 6% was the most effective botanical pesticide to control Sitophilus spp. and maintain the corn seed for 70 days in storage, compared with goatweed botanical pesticide at the doses of 2% and 4%, and also common lantana botanical pesticide in the doses of 2%, 4% or 6%. Key words : goatweed, common lantana, Sitophillus spp., corn seed
