After 24h, the lethal LC50 was 13.16μg / ml, LC90 was 65.25μg / ml; LC90 95% confidence interval was 68.57 ~ 62.09μg / ml. The results of potted and field plots showed that the control effect of aphids (Myzus persicae and Aphis gossypii) could be maintained at 84% or more after spraying for 14 days by 2000-3000 times, up to 100% In the field have a longer residual period.
