| Abstract: | In order to find out control effects of pymetrozine formulations on brown planthopper and their applications, field trials were carried out in 2013. The results showed that the control effects of pymetrozine 50% WG 300 g/hm2, pymetrozine 25% WP 600 g/hm2 were above 88% on the 28th day after spraying, and had significantly differences with pymetrozine 50% WP. And the persistent efficacy periods of the two formulations were longer than that of pymetrozine 50% WP. |
