Last Updated: 2024/11/09, Ordinary herbicides usually take six to seven days to volatilize in the field and fail in half a month. Some of the more toxic herbicides take several years to fail. After spraying herbicides in farmland, the components of herbicides that are not absorbed by weeds will exist.

Ordinary herbicides usually take six to seven days to volatilize in the field and fail in half a month. Some of the more toxic herbicides take several years to fail.

After spraying herbicides in farmland, the components of herbicides that are not absorbed by weeds will exist in the soil. Crops will absorb and accumulate herbicides, and their biological tissues will be destroyed to a certain extent, unable to synthesize some nutrients they should have, resulting in the loss of some nutrients in crop fruits.

Under the condition of normal dosage, herbicides have a certain inhibitory effect on wheat, corn, soybean, cotton and other crops. If the use is unreasonable, it will affect the normal development and maturity of crops and lead to recessive yield reduction. Studies in Hunan Province have shown that the side effects of herbicides can reduce the yield of rice, wheat, soybeans and corn by 10.5% to 26.8%.
