2008년선택료사충살충제진행료방치수도이화명、도종권협명적전간약제시험,결과현시:20%강관(CoregenTM)150ml/hm2방효최호,기살충、보수화보협효과균초과95%,50%령와1200ml/hm2、20%해천수1350ml/hm2,15%아유독1800ml/hm2방치효과야교이상,기살충、보수화보협작용분별체90%좌우,4충신형살충제적방치효과현저우우상규약제--90%살충단sp(900g/hm2)18%살충쌍(3000g/hm2),재시험제량하,4충살충제대수도적정상생장무영향,안전성호.
Four different types of insecticides were steted on their controlling effects on Chllo suppressalis and Cnaphaloerocis medinalis .The results showed that 20% Coregen TM gave the best results and 50% Ling Wa EC ande 20% Jie qian chou EC and 15% A wei du also gave good effects. They all showed no damage on rice growth.
