Description

technical field [0001] The invention relates to the field of pesticides, in particular to a Chinese herbal medicine compound fungicide mancozeb for preventing and treating rice sheath blight. Background technique [0002] Rice sheath blight, also known as moire, is commonly known as flower foot stalk, rotten foot blast, eyebrow spot. It is caused by infection by Rhizoctonia solani, and it mostly occurs under high temperature and high humidity conditions. Sheath blight is one of the major diseases in rice production, which is a serious hazard in southern rice areas. The disease prevents the rice from heading, or there are more grains in the heading, and the grain weight decreases. Most of the existing control agents are pure chemical agents. The use of pure chemical agents has the disadvantages of high efficiency, high price, and easy resistance of diseases and insect pests. The invention provides a compound prepared by compounding a small amount of chemical agents and Chi...
