The bactericide is prepared from the following active ingredients in mass fraction: 80 to 100 parts of calamine, 80 to 100 parts of cyrtomium rhizome, 80 to 100 parts of chinaberry bark and root bark, 50 to 70 parts of fructus cnidii, 50 to 70 parts of hydrargyri oxydum rubrum, 50 to 70 parts of radix tripterygii wilfordii, 50 to 70 parts of lightyellow sophora root, 40 to 60 parts of fatty alcohol polyoxyethylene ether, 40 to 60 parts of glycerin and 140 to 160 parts of distilled water. The plant bactericide disclosed by the invention has the advantages of high efficiency, environmental friendliness and suitable for being applied and popularized in a large scale in agricultural production.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a plant fungicide for preventing and controlling pests and diseases. Background technique [0002] In recent years, the occurrence of apple rot disease has been serious, and it has a wide range, ranging from young trees to old trees; There were two peaks in the incidence of rot disease. In March, new infected spots appeared and began to expand. The first incidence peak appeared from May to June, and the number and expansion suddenly decreased sharply in July. The second peak of incidence occurred in August and September. Basically stopped in late October. No new lesions appeared and no lesions expanded from November to next March. Corn is an important food crop. In recent years, the price of corn has been rising, and the majority of farmers attach great importance to corn production. At present, in addition to the cultivation and management of corn varieties and fertilization techn...
