How effective is acetochlor as a herbicide?

Acetochlor has been widely used as a herbicide, a selective pre-emergence treatment, mainly absorbed through the coleoptile of monocotyledonous plants or the hypocotyl of dicotyledonous plants, and after absorption it is translocated upward, mainly inhibiting cell growth by blocking protein synthesis, causing weed seedlings and young roots to stop growing and then die. Grass weeds have a stronger ability to absorb acetochlor than broadleaf weeds, so its control effect on grass weeds is better than on broadleaf weeds. Acetochlor has a residual life of about 45 days in the soil, is mainly degraded by microorganisms, has low mobility in the soil, and is mainly retained in the 0-3 cm soil layer.

Acetochlor herbicide can be applied to crops such as corn, cotton, beans, peanuts, potatoes, rapeseed, garlic, tobacco, sunflower, castor, and scallion, controlling annual grass weeds and some broadleaf weeds with small seeds. It has a special effect on annual grass weeds such as crabgrass, foxtail, goosegrass, barnyardgrass, Chinese sprangletop, shortawn foxtail, wild oat, annual bluegrass, hard grass, and lovegrass, and also has a certain control effect on broadleaf weeds such as Chenopodiaceae, Amaranthaceae, Polygonaceae, Asiatic dayflower, chickweed, and dodder, but the effect is worse than on grass weeds, and it is ineffective on perennial weeds.

Acetochlor herbicide has very high activity; when applying it, follow the instructions and do not increase the dose at will.
