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 longer (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.
Acetochlor is a selective pre-emergence herbicide for soybeans, peanuts, corn, canola, sugar cane, cotton, potato, cabbage, radish, kale, broccoli, tomato, pepper, eggplant, celery, carrot, lettuce, sauerkraut, beans Vegetables, citrus, grapes, orchards and other dry crops are pre-emerged to control annual grass weeds and some dicotyledon weeds and soybeans. The preparation has 90% Wones emulsifiable concentrate, 50% acetochlor EC, 88% acetochlor EC and 20% acetochlor wettable powder.
Instructions:
Generally, the dosage of the acre is 50-70 grams, and the water is 40-60 kilograms. After fully mixing, the weeds are evenly sprayed on the soil surface before the crops are sown, and the mulch film is applied before the film is applied.
There are many people in the area who grow soybeans and peanuts. Acetochlor is generally used as a pre-cast herbicide.
The specific method is that when corn, soybeans, peanuts, etc. are released, the seedlings are quickly combined with the seedlings, and then 150 ml of acetochlor is applied to the acre, and 90 kg of water can be sprayed. From sowing to Miaoqi squatting for about 30 days, the weather is dry and rainless, weeds are scarce, and broad-leaved weeds such as alfalfa and anti-branches are concentrated and sprouted, which saves labor. Since the spraying has been postponed for more than 30 days, the efficacy of the drug has been postponed backwards. By the time of the efficacy period, the crops have been tightly sealed, and even if there are a few weeds, they are incapable, as long as a small amount of broadleaf weeds can be removed. Such a time-lapse spray is both labor-saving and efficient, and also increases production.

(2) When spraying, the ground can be sprayed, and the application cannot be repeated. Otherwise, the crop has been phytotoxic.
(3) Acetochlor is sensitive to crops such as cucumber, spinach, leeks and wheat, and should not be used.
(4) Acetochlor has a stimulating effect on eyes and skin. When using it, care should be taken to take necessary protective measures.
