田间试验结果表明，１０％吡虫啉防治稻飞虱速效性较好，且高效持效。田间适宜药量为１０～２０ｇ／６６７ｍ２，药后１～５天，对稻飞虱校正防效达８４６％～９５３％，极显著优于对照药剂２５％噻嗪酮２５ｇ／６６７ｍ２，防效（４４５％～８０３％）。控效期达３０天以上。与８０％杀虫单４０ｇ／６６７ｍ２混配可有效防治稻纵卷叶螟，药后５天，校正防效达９２４％～９４４％。在实行害虫兼治中，宜在稻虱若虫发生为主期，掌握纵卷叶螟防治适期施药为好。 The results of field experiments showed that 10% imidacloprid was effective in controlling planthoppers and was efficient and effective. The optimum dosage in the field was 10 ~ 20g / 667m2. After 1 ~ 5 days, the correct control effect on planthoppers was 846% ~ 953%, which was significantly better than 25% buprofezin 25g / 667m2 , Control effect (44  5% ~ 80  3%). Control effect of more than 30 days. When mixed with 80% pest control single 40g / 667m2, the control effect of rice leaf roller could be effectively controlled and the control effect reached 924% ~ 944% after 5 days. Pest in the implementation of pest and disease, should be in the main phase of nymphs, the control of the leaf roller to control the appropriate application as appropriate.
