Material overview
Rhubarb palmatum has the functions of purging, promoting secretion of pancreatic fluid, promoting bile secretion and anti-liver injury.
Rhubarb stems can be used as a filling for desserts, jams or western pies
Benefits
Emodin methyl ether is a highly active plant source fungicide, which is made from natural plant rhubarb with its active ingredients carefully extracted and processed. It has a good control effect on powdery mildew, down mildew, gray mold and anthracnose. Low toxicity to humans and animals, friendly to the environment, especially suitable for green and organic vegetable production. Emodin methyl ether is a protective fungicide, inducing crop defense response, inhibiting pathogen spore germination, mycelium growth, haustorium formation, so that crops are protected from pathogens, to achieve the effect of disease prevention.
Application
Early emodin methyl ether is mainly used in the pharmaceutical industry, at present, with the in-depth research of emodin methyl ether in agricultural applications are gradually open out, with natural plant rhubarb as raw materials, after careful extraction of its active ingredients, processing and development of emodin methyl ether is a highly active plant source fungicide.
Practice has proved that 0.5% emodin methyl ether AS has a good control effect on powdery mildew, downy mildew, gray mold, anthrax and so on. It is low toxic to humans and animals, friendly to the environment, and not easy to produce resistance, because it contains a lot of humic acid and amino acids, and can effectively promote the growth of crop shoots and shoots, and can be used as an alternative to conventional high-toxic and high-residue pesticides.
Especially suitable for green and organic vegetable production. Emodin methyl ether is a protective fungicide, inducing crop defense response, inhibiting pathogen spore germination, mycelium growth, haustorium formation, so that crops are protected from pathogens, to achieve the effect of disease prevention.
