利用热雾机施药防治植物病虫害,是植保施药机具研究的一个新进展。1976年巴西、1977年马来西亚分别从美国引进了热雾机,在防治橡胶病害上作了试验。马来西亚用热雾机喷撒十三吗啉油剂防治橡胶白粉病取得比喷硫磺更好的效果。据称,每台热雾机每天可喷1200～2000亩,喷高30米,有效喷幅150米。1981年我们从美国太法公司引进了一套热雾机。1981—1982年,我们进行了十三吗啉的室内筛选试验,同时筛选对橡胶无害的喷雾油,发现十三吗啉和许多喷雾油对橡胶叶片有药害,只有一种喷雾油无药害。此时,我们在苗圃筛选一种新药——粉锈宁对橡胶白粉病有优异的效果。1983年我
The use of hot fog machine pesticide plant disease and insect prevention and control, is a new development of plant protection pesticide application. In 1976 Brazil, Malaysia in 1977, respectively, the introduction of the United States from the hot fog machine, in the prevention and control of rubber disease has been tested. Malaysia with hot fog machine spraying tridemorph oil control rubber powdery mildew achieved better results than spraying sulfur. Allegedly, each hot mist machine can spray 1200 ~ 2000 mu per day, spray 30 meters high, effective spray amplitude of 150 meters. In 1981 we introduced a set of hot fog machines from American too. In 1981-1982, we carried out an indoor screening test of tridemorph, and screened the spray oil which is harmless to the rubber. It was found that tridemorph and many spray oils were harmful to the rubber leaves. Only one type of spray oil was used, harm. At this point, we are screening a new drug at the nursery - triadimefon has an excellent effect on rubber powdery mildew. 1983 I
