每667m2用25%噻嗪·速灭威EC50～75g,施药后2～15d调查表明,对水稻田稻飞虱的防效稳定在80%以上,其速效性明显优于单用25%噻嗪酮WP,慢于单用25%速灭威WP单用,持效期明显优于单用5%速灭威WP,与25%噻嗪酮WP相当,对水稻的生长发育无明显影响,安全性较好,是防治稻飞虱的理想药剂。 Each 667m2 with 25% thiazide speed off Granville EC50 ~ 75g, 2 ~ 15d after application of the survey showed that the control effect on rice planthopper Stabilization of more than 80%, the quick-effect was significantly better than the single with 25% thiophene Azoxystrobin WP was slower than single WP with 25% methotrexate alone. Its duration of effect was significantly better than that of WP with 5% methotrexate alone. It was comparable to WP with 25% bupropion and had no significant effect on the growth and development of rice. Good security, is the ideal agent for planthopper control.
