Herbicides, as the name suggests, are agents that destroy or inhibit plant growth. The use of herbicides in agricultural production has a history of many years. The current mainstream herbicides are mainly divided into biocidal and selective herbicides according to their functions. Biocide herbicides simply means killing all crops regardless of the crop, mainly used before sowing; selective herbicides are made in a targeted manner according to the different resistance levels of different types of seedlings, and can theoretically kill weeds. Grass, which is harmless to seedlings, is actually not perfect for many reasons. Today, Xiaobian brings you an introduction to the types and characteristics of commonly used herbicides.

1. High activity, measured in grams per hectare.
2. The weeding spectrum is wide, and the weeding spectrum of different varieties is very different.
3. Strong selectivity, high safety to crops, and high efficiency to weeds.
4. It is easy to use and can be absorbed by the roots, stems and leaves of weeds, and can also be treated by soil.
5. The main target of action on plants is acetolactate synthase, which does not affect the germination and emergence of seeds. Weeds stop growing quickly after receiving the drug, but it takes a long time to die.
6. It is easy to cause acid hydrolysis.
7. Safe for mammals. It is easy to decompose and does not accumulate in the environment, and some varieties have a long lasting effect in the soil, which may cause phytotoxicity to subsequent crops.
