赣南脐橙产区应用有人直升机防治柑橘木虱 控制柑橘黄龙病初报

防治柑橘木虱是遏制柑橘黄龙病扩散的关键措施之一，应用有人直升机防治柑橘木虱目前还没有相关文献报道。本文介绍了赣南脐橙产区在嫩梢期应用有人直升机防治柑橘木虱的做法及成效。结果表明：有人直升机施药雾化性能较好，雾滴附着率高，雾滴分布较均匀，14个处理607个雾滴检测样本平均雾滴密度13.33 粒/cm2，雾滴密度符合农业航空植保技术作业要求；各处理对柑橘木虱均有很好的防治效果，药后7 天，防效都达90%以上。有人直升机具有作业效率高、突击能力强、不同地形地貌适应性好等特点，能在短时间内大面积施药作业，对失管果园、隔离带和杂草上的木虱也能同时防治，解决了一家一户防治时间不统一的问题，可以大面积减少虫口基数，是目前柑橘黄龙病发生区可以借鉴应用的重要技术措施。提出了加快农药产品的研发和登记、防范发生次生灾害、完善防治技术及轮换用药避免产生抗药性等建议。

A Preliminary study on the control of Citrus psyllid in Citrus Huanglong disease by using helicopter in navel orange production areas in the South of Jiangxi Province

Controlling Citrus psyllid is one of the essential measures to curb the spread of citrus Huanglong disease, Application of helicopter for Citrus psyllid controlling has not yet been reported. In this paper, the methods and effects of Citrus psyllid controlling by helicopter in navel orange producing areas in the South of Jiangxi Province was described .The results showed that helicopter spraying atomization performance is satisfied with high droplet attachment rate and good distribution uniformity . The average is 13.33 tablets / cm2of 607 droplet detection samples among the 14 treatments, The droplet density could thus meet agricultural aviation plant protection technology requirements; All treatments had good control effect to reached above 90% after treatment for 7 days. Due to the high operating efficiency, strong assault capability and good adaptability to different terrain , Helicopter can work in large area in a short time, meanwhile, it can also control Citrus psyllid in loss of orchards, isolation belt and weeds. This technical measures can solve the problem of prevention and treatment of non-uniform, reduce the population base in epidemic area of Citrus huanglongbing, The prevention and controlling measures this study put forward to accelerate the research and register of pesticide products, prevent secondary disasters occur, perfect the helicopter application technology and apply pesticide rotation to avoid resistance and others based on the results.
