龙眼的病虫防治工作历来未被人们所重视。我们处在龙眼的老产区,深深体会到龙眼病虫害的严重威胁,例如果蛀虫为害曾造成采前落果11~15%;霜霉病曾造成采前落果27%;荔枝椿象为害曾造成部分龙眼园花、果落尽;枝叶茂密的龙眼园曾被青翅羽衣为害造成遍地飞絮,并引发满园煤烟病;金龟子为害曾造成幼年龙眼园叶片所剩无几。所有这些病虫害,若不加速研究防治,很有可能蔓延发展,酿成大灾。这一严重情况,特提出希望引起有关方面的重视。
Longan pest control has never been valued. We are in the old producing areas of longan and are deeply aware of the serious threats to longan pests. For example, the damage caused by borers has caused 11-15% of plucked plucked fruits; the downy mildew has caused 27% of plucked plucked fruits; Longan garden flowers, fruits fall; lush branches of the longan garden had been caused by the green-winged plumage flooding floc, and cause the park soot; pest damage caused by young leaves long orchard leaves nothing left. All of these pests and diseases, if not accelerated research and control, are likely to spread the development and cause disaster. In this serious situation, I hope I can draw the attention of the parties concerned.
