氯虫苯甲酰胺对棉花棉铃虫的田间药效

Control Efficacy of Chlorantraniliprole to Bollworm in Cotton Fields

为了明确氯虫苯甲酰胺对棉花棉铃虫的防治效果,以生产上防治棉铃虫常用的3种化学药剂为对照,进行了200 g/L氯虫苯甲酰胺悬浮剂施用量225 m L/hm2对棉花棉铃虫的田间药效试验。结果表明:氯虫苯甲酰胺持效期可达到15 d,最高校正防效为88.10%,具有高效和持效期长的特点,且对棉花生长安全,其毒性为微毒,可在生产上推广使用。

In order to clarify the control efficacy of chlorantraniliprole on bollworm in cotton fields,taking 3 kinds of commonly used chemicals in production as controls,field efficacy experiments were conducted with 200 g / L chlorantraniliprole suspending agent 225 m L / hm^2 for cotton bollworm.The results showed that the effective duration of chlorantraniliprole could reach 15 d,the highest correction control effect was 88.10%,it with characteristics of high efficiency,long effective period,slight toxicity,and safe to the growth of cotton,so it could be popularized in production.
