摘 要：
The field efficacy trial of dinotefuran 20% SG was conducted to confirm the control effect on Lygus lucorum Meyer-dür.[Results] The results showed that the efficacy of dinotefuran 20% SG at 450,300,225,150 g a.i./ha and malathion 50% EC at 750 mL a.i./ha were 100,80,81.82,75 and 50% respectively against L.lucorum Meyer-dür on the first day after treatment,the efficacy were 100,100,94.29,80.25 and 46.45% on the third day,and 100,95.15,95,80.11 and 41.86% on the seventh day.[Conclusions] Dinotefuran 50% SG has advantages of readily availability,persistence and safety on cotton,which is an ideal pesticide in protecting cotton from L.lucorum Meyer-dür,the usage is 150-225 g a.i./ha in medium to light years,while 225-300 g a.i./ha in medium to large years
