The results showed that 60% of the WP single WP was highly effective against planthoppers, with 6 6 7m 2 40g and 80 g respectively. The control effects of spraying 80g on the water one day after treatment were 62.4% and 66.7% After 20d control efficiency was 84 3%, 89 7%. 25% with the control agent Puer Ling WP comparable, persistence 20d or more. In the production, 60% of the WP single WP to combat planthoppers, the cost-effective per 6 6 7m2 40 ~ 80g.
