Abstract: | Objective ] The controlling efficiency of the 75 % pymetrozine WP on rice hopper was identified for the extension in production. Method] The test treatments of 66.00 g/hm2 75% pymetrozine WP, 100.05 g/hm2 75% pymetrozine WP andl60.05 g/hm2 75% py- metrozine WP were adopted, with 300.00 g/hm2 75% pymetrozine WP as CK, the control effect of those treatments on rice hopper was stud- ied. Result] Average control effect of 66.00 g/hm2 75% pymetrozine WP, 100.05 g/hm2 75% pymetrozine WP and 160.05 g,/hmz 75% pymetrozine WP was 71.75% ,79.19% ,84.60% 3 days after treatment, and the average control effect was 71.75% ,79.19% ,84.60% 20 days after treatment. Conclusion] The control effect of 160.05 g/hm2 75% pymetrozine WP on rice hopper was good. |
