Problems solved by technology

[0002] Herbicide is a widely used agricultural product, which is mainly used to curb weeds' competition for soil nutrients during crop growth. Chemical herbicides are favored by farmers for their high efficiency and quickness. However, they decompose slowly in the soil And it is toxic, and it is easy to accumulate in crops, thereby threatening the health of eaters. Therefore, people are committed to researching a high-efficiency, high-release efficiency, and a high-efficiency herbicidal composite material with low residues to solve the problems in the prior art.
