使用不同种类的化学药剂,并且借助烟雾机来对落叶松尺蛾予以防治的过程中,选择的药物类型和药物的浓度可能会对落叶松尺蛾防治起到不同的效果。对此展开研究发现,使用40倍的浓度为4%左右的氯氰菊酯,对落叶松尺蛾起到的防治效果最理想,而且成本也相对较低,比起其他的药剂来说值得推广、使用。同时,提出如何防治森林病虫害。 The use of different types of chemicals and the control of larch moths with smoke machines may result in different effects on the control of larch moths, depending on the type of drug and the concentration of drug. The study found that the use of 40 times the concentration of about 4% of cypermethrin, larch moth played the most effective control effect, and the cost is relatively low, compared to other agents worth promoting, use. At the same time, put forward how to control forest pests and diseases.
