Early emodin methyl ether is mainly used in the pharmaceutical industry. At present, with the research, the application of emodin methyl ether in agriculture has been gradually opened up. The natural rhubarb is used as raw material, and the active ingredients are carefully extracted to produce rhubarb. Methyl ether is a highly active plant-derived fungicide. It has been proved that 0.5% emodin methyl ether AS has good control effects on powdery mildew, downy mildew, gray mold and anthracnose. It is low-toxic to humans and animals, environmentally friendly, and resistant to drug resistance. Because it contains a large amount of humic acid and amino acids, it can also effectively promote the growth of crop shoots and sprouts. It can be used as a substitute for conventional high-toxic and high-residue pesticides. It is especially suitable for the production of green and organic vegetables. The emodin methyl ether is a protective fungicide, which induces a protective response of the crop, inhibits the spore germination of the pathogenic bacteria, the growth of hyphae, and the formation of a sip, so that the crop is protected from pathogenic bacteria and the disease prevention effect is achieved.
