Atrazine herbicide is a versatile herbicide for corn fields, usable both pre- and post-emergence. It ensures clean and thorough weed control, is cost-effective, and has a long-lasting effect. Many corn growers use atrazine herbicide. Let's discuss its application scope.
Application Scope of Atrazine Herbicide
1. Application Range
Atrazine herbicide is suitable for dryland crops such as corn, sorghum, sugarcane, fruit trees, nurseries, and forest land. It can control weeds like crabgrass, barnyardgrass, foxtail, nutsedge, wild oats, knotweed, lambsquarters, cruciferous, and leguminous weeds. It is especially selective for corn and has some inhibitory effects on certain perennial weeds.
2. Usage Methods
Single Use
To control common weeds in cornfields, apply 50% atrazine dispersible concentrate at 150-250 ml per mu (approximately 0.067 hectares) before sowing or at the 3-5 leaf stage of corn and the 2-5 leaf stage of weeds. Mix with 15-20 kg of water and spray evenly. This effectively kills weeds such as crabgrass, redroot pigweed, green foxtail, yellow foxtail, goosegrass, nightshade, barnyardgrass, millet, lambsquarters, purslane, amaranth, kochia, and more.
Combination Use
To control perennial weeds like field bindweed, reed, and yellow nutsedge, apply 37% atrazine dispersible oil suspension at 60-80 ml per mu during the 3-5 leaf stage of corn and the 2-6 leaf stage of weeds. Mix with 25-30 kg of water and spray on stems and leaves.
Main Features of Atrazine Herbicide
1. Broad Weed Control Spectrum
Atrazine effectively kills a wide range of annual broadleaf and grassy weeds such as volunteer wheat, crabgrass, barnyardgrass, foxtail, nutsedge, wild oats, knotweed, and lambsquarters, as well as some perennial weeds.
2. Wide Application Range
In addition to corn, atrazine can be used for sorghum, sugarcane, fruit trees, nurseries, forest land, tea gardens, rubber plantations, and forests.
3. High Safety
When used at the recommended dosage, atrazine is very safe for corn and highly effective against weeds, without causing phytotoxicity. It has a residual effect in the soil for about six months, making it safe for subsequent broadleaf and grassy crops.
4. Good Mixing Compatibility
Atrazine is primarily used for small weeds and is less effective against larger weeds such as nutsedge, thistle, and goosegrass. Due to its excellent mixing compatibility, it can be combined with almost all corn herbicides, expanding the weed control spectrum, enhancing efficacy, and reducing the amount of herbicide needed.
5. Cost-Effectiveness
With mature production processes and large market demand, atrazine is very affordable, with a cost of only 2-3 yuan per mu, making it accessible for farmers.
In summary, atrazine is a selective, systemic herbicide used pre- and post-emergence, widely applied to various corn varieties.
