In order to assess effects of 4 invasive plants, namely, Ipomoea cairica, Lantana camara, Ageratum conyzoides, and Wedelia trilobata from the same origin area of golden snail (IPSOAGS) on its behavior and killing activity, the golden snails congregating number (GSCN) and eating weight among the fresh leaves of 4 IPSOAGS and 3-4 leaf stage Oryza sativa(rice) seedlings were investigated. GSCN among 4 selected IPSOAGS and rice seedlings showed significant differences in the distance about 75cm after 15 mins, but the GSCN were stable after 75 mins, and the GSCN from larger to small were W. trilobata, L. camara, rice, A.conyzoides, and I. cairica. Golden snail eating weight of rice seedling was significantly higher than that of 4 IPSOAGS leaves, and the golden snail eating weight from small to large were rice, I. cairica, W. trilobata A.conyzoides, and L. camara. Different concentrations of water solution of 4 IPSOAGS leaf ethanol extracts showed significantly different killing effects on golden snail. The time length of 100% killing golden snail with saturated water solutions of ethanol extracts from short to long were I. cairica (48h), W. trilobata (72h), and both A.conyzoides and L. camara were the same (96h), compared the Meta with 0.30 g•L-1 was 118h. It can be concluded that I. cairica has potentials to develop a material both controlling golden snail and environmental friendly in rice production.
