Triadimefon is a new efficient, long-lasting, broad-spectrum, low toxicity systemic fungicide. 1970 Bayer company developed by the West, the test code Bay Meb6447, commonly known as Triadimefon, trade name Bayleton, belonging to the triazole class, the chemical name is [1- (4-chlorophenoxy) -3,3-bis Methyl-1- (1-hydro-1,2,4-triazol-1-yl) -2-butanone]. The country was synthesized by the elements of Nankai University in 1977, and then, Shenyang Chemical Industry Research Institute and Sichuan Chemical Industry Institute also synthesized the drug. The main control targets of triadimencinum are powdery mildew, rust and powdery mildew. In addition, powdery mildew on melons, apples and beets, rust on pears, grapes, peas and coffee,
