| Abstract: | Imidacloprid,a new insecticide,was used to control thrips(Thrips oryzae Williams) in rice seedling field by seed dressing.At the dosage of 70,140 and 210 g a.i./100 kg rice seed,the control effect were 98.1%,97.6% and 98.6% respectively,and the action lasted 30 days.In the foliar application of imidacloprid at dosage of 60 g a.i./ha,the control effect was 90.6%(1 day after application),87.8%(3 days after application) and 88.3%(7 days after application).Imidacloprid is safe to rice seedling and can be used as a new tool to control thrips. |
