氟啶虫酰胺属于吡啶酰胺类杀虫剂,为了探明其对柑橘木虱、粉虱、蚜虫、潜叶蛾等柑橘嫩梢期主要害虫的防治效果,于2014年进行了田间小区药效试验。结果表明,氟啶虫酰胺10%可湿性粉剂对柑橘蚜虫(桔蚜和桔二叉蚜)的防效最好,33.3mg/L药后3、7d的防效都超过97.7%;其次是柑橘粉虱,药后2~20d防效为61.52%~86.75%;对柑橘木虱和潜叶蛾的防效较差。防治柑橘木虱的2次试验,仅25.0mg/L在药后3d的防效达56.5%,其余防效均低于50%;33.3mg/L对柑橘潜叶蛾药后5d的防效为34.66%;氟啶虫酰胺10%可湿性粉剂对柑橘蚜虫和柑橘粉虱的防效较好,推荐使用浓度为33.3~50mg/L;对柑橘木虱和柑橘潜叶蛾的防效较差。
Flonicamid belongs to the class of picolinamide insecticides. In order to find out its control effect on the main pests of citrus young plants, such as citrus psylla, whitefly, aphid and leaf-spot moth, field efficacy test was conducted in 2014 . The results showed that fluticidin 10% wettable powder had the best control effect on citrus aphids (orange aphid and orange aphid), and the control effect was over 97.7% at 33.3 mg / L 3 and 7 days after treatment. The second was citrus Whitefly, 2 ~ 20d after drug control effect was 61.52% ~ 86.75%; on citrus psyllid and leafminer control effect is poor. The control efficacy of citrus psyllid was only 56.5% at 25.0mg / L for 3 days and less than 50% for other control. The control efficacy of 33.3mg / L for 5d after citrus was 34.66%. The control effect of flonicamid 10% wettable powder on citrus aphids and citrus whiteflies was 33.3 ~ 50mg / L. The control effect on citrus psylla and citrus leafminer was poor.
