| Abstract: | The results of field efficacy trails showed that the e fficiencies of 1, 3, 8 days after treatment of Kuailing (90%WP) at the concentra tion of 1∶3?000 a gainst Heliothis assulta was better than Miman's (24%FF) at the concentration of 1∶1?500 and the efficacy of 3 days was up to best (100%) and the efficacy of 8 d ays was similar to 90%. The efficacy of 16 days after treatment of Kuailing (90% WP) being equal to Miman's (24%FF) was about 70%. The efficiency of 1,3,8,16 days after treatmen t o f Miman (24%FF) at the concentration of 1∶1?500 was continually increasing and the efficacy of 8 days was up to best (74.46%). |
