Problems solved by technology

During the planting process of corn, it will be infected by various diseases. Among them, brown spot is a serious and rapid corn disease that has occurred in my country in recent years. Shandong, Henan, Anwei and other provinces are more harmful. The disease mainly occurs on corn leaves, leaf sheaths and stalks. After the onset, the epidermis of the lesions ruptures, and the leaf cells become necrotic. Tebuconazole, etc., will also prepare potassium dihydrogen phosphate and diammonium phosphate aqueous solution for adjuvant treatment, but long-term use of chemical agents not only causes the decline of drug efficacy, but also pollutes the soil and the environment.
