      摘要
    • 摘要: 为筛选出适宜防治稻飞虱的新农药,并确定其最佳使用剂量,进行3种农药防治稻飞虱的田间药效对比试验,结果表明:25%噻嗪酮WP、20%敌百虫·仲丁威EC、25%噻嗪酮·丙溴磷WP 3种农药均能有效防治稻飞虱,其中25%噻嗪酮WP的防效最好,其后依次为25%噻嗪酮·丙溴磷WP和20%敌百虫·仲丁威EC。生产上推荐每667 m2使用剂量为25%噻嗪酮WP 20 g、25%噻嗪酮·丙溴磷WP 75 g、20%敌百虫·仲丁威EC 225 mL。

       

      Abstract: An efficacy trial of three pesticides on rice planthopper was carried out in field in order to select the suitable pesticide and determine the optimal dosage for rice planthopper in Ninghua County. The results showed that 25% buprofezin WP, 20% trichlorfon·fenobucarb EC, and 25% buprofezin·profenofos WP had efficient controlling function to planthopper, and the control efficiency of 25% buprofezin WP was the best, the follows were 25% buprofezin·profenofos WP and 20% trichlorfon·fenobucarb EC. The recommended doses for application in field production were 25% buprofezin WP 20g, 25% buprofezin·profenofos WP 75g, and 20% trichlorfon·fenobucarb EC 225 mL per 667 m2 respectively.
