Gramineous weeds are absorbed by the roots, broad-leaved weeds are absorbed by roots and shoots, and the agents absorbed into the body can perform nucleic acid metabolism and protein synthesis. The young shoots, the young roots stop growing and eventually die. It can last for about 2 months in the soil.
The amount of acetochlor is related to soil moisture and organic matter content. The dosage should be determined according to different seasons, different crops and grass conditions. Sand with low organic matter content should be used in low doses. When the medicine is applied at high temperature or it is rained after application, the amount of the seed contacted with the medicine produces phytotoxicity. After emergence, the leaves shrink and yellow.
After the weeds are damaged, the young roots and the young shoots are inhibited, and the leaves cannot be extracted from the buds or the leaves are deformed, and become shorter and thicker and die.
