description
Alachlor is a pre- and postemergence herbicide used to control annual grasses and many broad-leaved weeds in corn and in many other crops. There are liquid, dry flowable, microencapsulated, and granular formulations. Alachlor is applied by ground, aerial, and chemigation equipment. It can also be mixed with dry bulk fertilizer. It is lost from soil mainly through volatilization, photodegradation, and biodegradation. Alachlor and its degradation products may be found in soil, groundwater, and surface water.

Uses
It can be used as selective herbicide for dryland bud. If a plant bud absorbs the agent, it can inhibit the activity of the protease and hinder protein synthesis, resulting in the death of weeds. It is mainly used for the germination of weeds in the soil before the seedlings, which is basically ineffective for the unearthed weeds. It can prevent annual grasses in the fields of dryland crops such as soybean, cotton, sugar beet, corn, peanut and rape, such as barnyard grass, Goosegrass, autumn grass, crabgrass, Goosegrass, Setaria, Brachiaria etc. Alachlor is used pre- or early post-emergence to control annual grasses and many broadleaved weeds mainly in maize, but also in cotton, brassicas, oilseed rape, peanuts, radish, soy beans, and sugar-cane. Alachlor is one of the most widely used herbicides in the
United States and is used as an herbicide for grasses, broadleaf
seeds, corn, sorghum, soybeans, peanuts, cotton, vegetables,
and forage crops. Preemergence, early postemergence or soil-incorporated herbicide used to control
most annual grasses and many annual broad-leaved weeds in beans, corn, cotton, milo,
peanuts, peas, soybeans, sunflower and certain woody ornamentals.
