为探讨抗病毒剂毒氟磷与杀虫剂吡蚜酮·噻虫嗪混合使用对水稻条纹叶枯病的防治效果，进行了25％吡蚜酮·噻虫嗪SC和30％毒氟磷（病毒星）WP的单独与混和使用对水稻灰飞虱及水稻条纹叶枯病的防效试验。结果表明：吡蚜酮·噻虫嗪单用或与毒氟磷混用对秧田灰飞虱成虫和水稻条纹叶枯病均具有较好的控制效果，在灰飞虱大发生年份，秧田第4次药后7 d防效为78％～89．50％，对水稻条纹叶枯病防效为70％～78．94％，以25％吡蚜酮·噻虫嗪SC 525 mL＋30％毒氟磷 WP 990 g混合使用的效果较佳。
為探討抗病毒劑毒氟燐與殺蟲劑吡蚜酮·噻蟲嗪混閤使用對水稻條紋葉枯病的防治效果，進行瞭25％吡蚜酮·噻蟲嗪SC和30％毒氟燐（病毒星）WP的單獨與混和使用對水稻灰飛虱及水稻條紋葉枯病的防效試驗。結果錶明：吡蚜酮·噻蟲嗪單用或與毒氟燐混用對秧田灰飛虱成蟲和水稻條紋葉枯病均具有較好的控製效果，在灰飛虱大髮生年份，秧田第4次藥後7 d防效為78％～89．50％，對水稻條紋葉枯病防效為70％～78．94％，以25％吡蚜酮·噻蟲嗪SC 525 mL＋30％毒氟燐 WP 990 g混閤使用的效果較佳。

Field experiments were conducted to control rice stripe virus disease and L.striatellus with different pesticides of 25% Pymetrozine·thiamethoxam SC,25% Pymetrozine·thiamethoxam SC+30%Dufulin WP,30% Dufulin WP.The results showed that Pymetrozine · thiamethoxam SC,the pesticide mixture of Pymetrozine · thiamethoxam SC and Dufulin WP,could provide good effects against L. striatellus adults.In the years of outbreaks of L.striatellus,the control efficacy was 78%~89.50% at the seventh days after the fourth use of the pesticides;The control efficacy to rice stripe virus disease was 70%~78.94%.25% Pymetrozine·thiamethoxam SC+30% Dufulin WP 990 g could provide good effects against stripe virus disease.
