Scope and method of use of acetochlor

Acetochlor is a widely used herbicide . Among the soil treatment herbicides commonly used in corn fields, acetochlor is a must-have for closed weeding in almost all corn-producing areas. Below we will introduce the scope and methods of using sethoxydim.

Scope of use of acetochlor

Acetochlor is a broad-spectrum herbicide that can be used in corn, soybeans, peanuts, rapeseed, rice, cotton, sugarcane, tea gardens, transplanted vegetables (cabbage, kale, cauliflower, tomatoes, peppers, eggplants, etc.), citrus, grapes, orchards, etc. It is mainly used to control annual grass weeds and small-grained broad-leaf weeds, such as long-awned barnyard grass, crabgrass, foxtail grass , goosegrass, Leptochloa chinensis, alopecuroides, bluegrass, wild oats, and coleus, as well as various broad-leaved weeds such as Amaranthus retroflexus, Amaranthus angustifolia , Chenopodium album, Purslane, Solanum nigrum, Rumex sylvestris, Polygonum aviculare, and Commelina .

Characteristics of Acetochlor

1. Diverse mechanisms of action

Acetochlor is a chloroacetamide pre-emergence herbicide. When the agent enters the weeds, it interferes with nucleic acid metabolism, inhibits the synthesis of long-chain fatty acids and proteins, causing the weed shoots to shrink and the young roots to stop growing.

2. Conductive

The drug can be absorbed by the young shoots of weeds, and can also be absorbed and conducted by seeds and roots, but the amount absorbed is smaller and the conduction speed is slower. After weeds emerge, they mainly rely on root absorption and conduction upwards.

3. Safety for the next crop

The effective period of sethoxydim is about 1.5 months. It can be degraded by microorganisms in the soil and has no effect on subsequent crops.

4. Sensitive crops

Sethoxydim is toxic to crops such as wheat, millet, sorghum, cucumber, and spinach and should not be used.

Precautions for use of acetochlor

1. When used after sowing and before seedlings emerge, spray it in time before weeds emerge within 1-2 days after sowing.

2. Determine the spray concentration and dosage according to the conditions of the plot. The amount of medicine can be appropriately increased for fertile land, while the amount of medicine should be reduced by 20% for barren land.

3. The spraying amount should be reduced in the plots covered with film and drip irrigation to prevent drip irrigation after sowing, which may cause the solution to seep into the seeds and cause pesticide damage.

4. Ensure the quality of land preparation to prevent uneven land from affecting the quality of spraying and the weed control effect.
