Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a medicament for preventing and treating rice sheath blight. Background technique [0002] Rice is an annual gramineous plant with a height of about 1.2 meters. It has long and flat leaves. The fruit it bears is rice, which is called rice or rice after shelling. Rice is an important food crop in the world, and its output accounts for 1 / 4 of the world's total food production. Above, accounting for more than half of China's total grain output, is the staple food that more than half of the world's population relies on. In addition to being edible, it can also be used for wine making, sugar refining or other industrial raw materials. Rice husks and rice straws also have many uses. During the cultivation and cultivation of rice, it will be threatened by various diseases, including rice blast, bacterial blight, sheath blight, rice false smut, bakanae disease, etc. [0003] At pres...
