超低容量喷雾是六十年代中期在国际上发展起来的新技术。由于它具有工效高、成本低、效果好、节省农药等优点,已有一些国家开始用于农业害虫防治。我国自1973年开始研究,1975年正式应用于农业生产。但至目前为止,在国内外仍主要用在防治虫害上,在林木病害防治上,尚未见到有关报道。1979年,吉林省林科所、吉林市林科所、敦化林业局和林业部安阳林药厂等单位应用安阳林药厂研制的百菌清杀菌油剂,对落叶松落叶病、枯梢病进行地面超低容量喷雾防治试验,取得了较好的防治效果。同时,根据我省几年来对落叶病、枯梢病的研究情况,已从理论和实验上为迅速开展对这两种病害使用一种防治技术,进行联合防治提供了依据。
Ultra-low volume spray is a new technology developed internationally in the mid-1960s. Because of its high efficiency, low cost, good effect, the advantages of saving pesticides, some countries have begun to be used for agricultural pest control. Our country started to study from 1973, formally applied to agricultural production in 1975. However, so far, they are still mainly used for pest control both at home and abroad. No reports have been found on the prevention and treatment of forest diseases. In 1979, Linke Jilin Province, Jilin City, Linke, Dunhua Forestry Bureau and the Ministry of Forestry Anyang Lin pharmaceutical and other units developed by Anyang Lin pesticide chlorothalonil agents, larch deciduous disease, blight Ultra-low capacity ground spray prevention and control tests, and achieved good control effect. In the meantime, according to the research situation of deciduous disease and blight-tip disease in our province over the past few years, it has been theoretically and experimentally provided a basis for the prompt implementation of a prevention and control technology and joint prevention and control for these two diseases.
