Everyone knows that acetochlor is a pre-emergence herbicide , and its toxicity is relatively low. It can be used to control grass damage such as horse pond, valerian, foxtail, purslane, etc. What is the application method of acetochlor in field crops? Let's follow the Xiaobian to understand it.
The role of acetochlor:
Acetochlor is a low-toxic herbicide, which is safe for humans, animals and crops. At the same time, the effective period of weed control is long (60-70) days. One application can control the weed damage in the whole growth period. Acetochlor is a selective herbicide that is mainly absorbed by the weeds and radicles of weeds, and the monocotyledonous weeds are absorbed by the buds. When the agent enters the weed body, it inhibits the growth of the young shoots and the young roots, and finally wilting and dying. Acetochlor can be used in various crops such as soybean, potato, cruciferous, and legumes. It mainly controls horse pond, valerian, foxtail, purslane, etc., but it is not effective for perennial weeds.
How to use acetochlor:
