| Mode of action: | Acetochler is a herbicide for selective prebud treatment. It is mainly absorbed by the coleoptile sheath of monocotyledons or the hypocotyls of dicotyledons, and then transmitted upward. It inhibits cell growth mainly by hindering protein synthesis, so as to stop the growth of weed shoots and young roots, and then die. |
| Uses: | Description: A chloroacetanilide herbicide used mainly pre-emergence or pre-planting to control annual grasses and some broad-leaved weeds Example pests controlled: Annual grasses including feathertop chloris, goosegrass, sweet buffalo grass and crab grass; Certain broadleaf weeds including morning glory, marigold, pigweed and cocklebur; Yellow nutsedge Example applications: Vegetables including cabbage, peas and onions; Fruit including citrus, apples, pears, plums, apricots; Coffee; Corn; Sugarbeet; Sugarcane; Potatoes |
The herbicide mixture of Acetochlor + Atrazine is widely used in corn (maize) and sorghum production for residual pre-emergence and early post-emergence weed control. This combination provides broad-spectrum control of both grasses and broadleaf weeds, leveraging their complementary modes of action.
Field Corn (Maize) - Most common use, applied pre-emergence or early post-emergence.
Sweet Corn - Some formulations are labeled (check restrictions).
Sorghum - Used for weed suppression in grain sorghum.
Sugarcane - Occasionally used for pre-emergence weed control.
Grasses: Foxtail, Barnyardgrass, Fall Panicum, Crabgrass.
Broadleaves: Pigweed (Amaranthus), Ragweed, Lambsquarters, Velvetleaf, Nightshade.
Some Sedges: Yellow Nutsedge (partial suppression).
Pre-emergence (Best) - Applied before weed seeds germinate, right after planting.
Early Post-emergence - Can be used before corn reaches 12 inches tall (check label).
Extended residual control - Acetochlor (a chloroacetamide) inhibits weed seedling growth, while Atrazine (a triazine) disrupts photosynthesis.
Broader spectrum - Controls both grasses and broadleaf weeds better than either herbicide alone.
Resistance management - Combining two modes of action (Group 15 + Group 5) reduces resistance risk.
Soil and Environmental Factors
Works best in medium to fine-textured soils (higher organic matter helps retain efficacy).
Less effective in sandy soils (higher leaching risk, especially for Atrazine).
Rainfall needed (~0.5-1 inch) to activate herbicides in soil.
Crop Safety
Do not use on crops other than corn/sorghum (high risk of injury to soybeans, vegetables, etc.).
Avoid overlapping sprays (can cause stunting in corn).
Environmental & Regulatory Concerns
Atrazine has groundwater contamination risks; some regions restrict its use.
Acetochlor requires incorporation (rain or irrigation) for best results.
