Herbicide

Herbicides refer to the agents that can completely or selectively cause the death of weeds, and they are also known as weed killers. Herbicides are divided into inorganic compound types and organic synthetic types. Herbicides should possess characteristics such as high efficiency, selectivity, and convenience in use. Some herbicides, such as paraquat, can function by inhibiting the photosynthesis of weeds, blocking the photosynthetic electron transfer or inhibiting the synthesis of photosynthetic pigments. Some herbicides, such as naphthalene acetic acid, can interfere with the hormonal balance of plants, leading to abnormal growth and death of weeds. There are also some herbicides that can inhibit plant cell division or amino acid synthesis. Herbicides are widely applied in agricultural farmlands, garden green spaces, along roads and railways, industrial sites, etc., to control weeds, so as to ensure the growth of crops, maintain the landscape environment, and reduce potential safety hazards such as fires^[1]^[2].
