Usage of atrazine

Atrazine can be used in corn fields, where the quality of soil organic matter is 1% Mur2%, 150-200 grams of 50% wettable powder or 175-200 ml of 40% suspending agent is used per mu, and 200-250 grams of 50% wettable powder or 200-250 grams of 40% suspending agent are used per mu in areas where the content of soil organic matter is more than 3% Murray 6%. After corn emergence, sandy soil uses 50% wettable powder or 40% suspending agent 200-250 grams per mu. In the continuous cropping area of corn and winter wheat, atrazine can be mixed with herbicides such as Caojingjin, Rasol, Chloromuron and so on.

Atrazine is a selective herbicide before and after seedling. The root absorbs mainly, but the stem and leaf absorb little. The herbicidal effect and selectivity are the same as simazine, which is easy to be leached to the deeper soil by Rain Water, and is also effective for some deep-rooted grasses, but it is easy to cause drug damage. The duration of effect is also longer.

Atrazine is not only a herbicide for soil treatment before bud, but also a herbicide for stem and leaf treatment after bud. Drought in use has a great influence on the efficacy, mainly on dicotyledons, focusing on closure, but not ideal on grasses.

It has a wide herbicide spectrum and can control a variety of annual Gramineae and broad-leaved weeds. It is suitable for dry field crops such as corn, sorghum, sugarcane, fruit trees, nursery, woodland, etc., to control Tripterygium, barnyardgrass, dogweed, sedge, sorghum, polygonum, quinoa, cruciferae, legume weeds, especially for corn (because of the detoxification mechanism in corn), it also has a certain inhibitory effect on some perennial weeds.
