Herbicidal effect of Acetochlor

Acetochlor has been widely used as a herbicide, selective pre-bud treatment, mainly absorbed by the coleoptile of monocotyledons or Hypocotyl of dicotyledons, transmitted upward after absorption, and inhibited cell growth mainly by hindering protein synthesis. stop the growth of weed buds and roots, and then die. The ability of Gramineae weeds to absorb Acetochlor is stronger than broad-leaved weeds, so the control effect of Gramineae weeds is better than that of broad-leaved weeds. Acetochlor lasted for about 45 days in soil, mainly through microbial degradation, and its mobility in soil was small, mainly in 0-3 cm soil layer.

Acetochlor can be applied to corn, cotton, beans, peanuts, potatoes, rape, garlic, tobacco, sunflowers, castor, scallions and other crops to control annual Gramineae weeds and some small seeds of broad-leaved weeds. It has a special effect on annual Gramineae weeds, such as Chenopodiaceae, Amaranthaceae, Polygonaceae, duckfoot grass, oxtail grass, grass grass, etc., but the effect is worse than that of Gramineae weeds and is ineffective to perennial weeds.

Acetochlor has high activity and should be used in accordance with the instructions, and the dosage should not be increased at will.
