Atrazine is a herbicide that is treated in soil before budding and can also be treated in stem and leaf after budding. Drought had a great effect on the drug efficacy, mainly on dicotyledonous plants, focusing on closure, and the effect on large grass was not ideal.
peculiarity | It is a selective pre - and post-emergence blocking herbicide. The root absorption was dominant, and the stem and leaf absorption was little. The herbicidal effect and selectivity are the same as Simazine, which is easy to be washed by rain to the deeper soil, and is also effective for some deep-rooted grasses, but it is easy to produce drug damage. The lasting period is also longer. |
Scope of application | The broad spectrum of killing grass can prevent a variety of annual grasses and broad-leaved weeds. It is suitable for corn, sorghum, sugarcane, fruit trees, nurseries, forest and other dry field crops to control the weeds of Matang, barnyard grass, dogtail grass, sedge, malifolia, polygonum, quinoa, cruciferous and leguminous, especially for corn (because of the detoxification mechanism in the body of corn), and some perennial weeds also have a certain inhibitory effect. |
Usage method | 1. The use of corn fields, summer corn after sowing before emergence, soil organic matter quality in North China, Shandong and other places in 1%-2%, with 50% wettable powder 150-200 grams per mu, or 40% suspension agent 175-200 ml; In Northeast China, where the soil organic matter content is greater than 3%-6%, 50% wettable powder is 200-250 grams per mu, or 40% suspension agent is 200-250 grams, the lower limit is used for sandy soil, and the upper limit is used for sticky soil. 1-3 days after sowing, spray the soil surface with 30 kg of water evenly. After maize emergence, the suitable period was maize 4-leaf stage and weeds 2-3 leaf stage. For sandy soil with low organic matter content, use 50% wettable powder or 40% suspension agent 200-250 grams per mu. Spray 30-50 kg of water. Spring corn per mu with 40% suspension agent 200-250 ml, add water 30-50 kg, after seeding before the soil surface spray, after spring drought medicine mixed soil, or appropriate irrigation. Or in maize 4 leaf stage for stem and leaf treatment. In order to reduce or eliminate the drug damage of atrazine to wheat in the continuous cropping area of maize and winter wheat, atrazine reduction can be used in combination with the herbicides of oxazine, Lasol, Dur, 2, 4-D butyl ester, Bandinong and chloromyron. 2. For use in sugarcane fields, 5-7 days after the planting of sugarcane, some weeds are unearthed. Use 50% wettable powder or 40% suspension agent 200-250g per mu, add 30kg of water, and spray evenly on the surface. 3. In tea gardens, orchards and vineyards, use the peak of field weed germination in April and May. First remove the unearthed large grass and wintering impurities, then use 40% suspension agent 250-300 grams per mu, and evenly spray the soil surface to 40 kg of water. |
Attention | 1. Atrazine has a long lasting effect and is harmful to subsequent sensitive crops such as wheat, soybean and rice, with a lasting effect of 2-3 months. It can be solved by reducing the dosage and mixing with other herbicides such as nimosulfuron or methyl sulfamone. 2. Peach trees are sensitive to atrazine and should not be used in peach gardens. Corn interbred beans can not be used. 3. When soil surface is treated, the ground should be smooth and fine before application. 4. After application, all kinds of tools should be carefully cleaned. |
