Abstract: Veratridine is a new type of botanical pesticides. A field experiment of 0.5% veratridine S C suppressing on eggplant red spider was conducted to verify the efficacy. The results showed that 0.5% veratridine solvent (×300) have control effect for red spider, control effect of 3 days after the first applying and 5 days after the second applying were low, however, 5 days after the last applying, the mean drug control efficacy reached 71.63%. Thus, this pesticide have poor quick result and good persistence effect when controlling the red spiders, and could be used before the high incidence of red spider in the spring, or used interchangeably with chemical pesticides to mitigate the effects of chemical pesticides on the environment and ecology.

Key words: 0.5% veratridine S C, eggplants, red spiders
