First, weed control techniques at sowing stage Atrazine (Atrazine) can control a variety of annual grasses and broad-leaved weeds, the weeding effect of broad-leaved weeds is better than grass weeds. Soil treatment can be carried out before and after sowing, or in the post-emergence corn 3-4 leaf stage, grassy weed 1-2 leaf stage, and broadleaf weed 3-4 leaf stage. Use 40% Atrazine Suspension 150-200ml/mu, increase the dose in soil with high clay soil and organic matter content.
Soil organic matter has a strong adsorption effect on atrazine, when the soil organic matter content exceeds 6%, due to the large amount of drug is not economical, should be changed to post-emergence stem and leaf treatment or use other herbicides. Post-emergence stem and leaf treatment with 200-270ml/mu is appropriate.
In the desolate areas, atrazine is used in excess of 133g/mu, and it is impossible to grow sensitive crops such as wheat, soybeans and millet. Pre-emergence soil treatment, prevention and control of annual grass weeds is better than post-emergence stem and leaf treatment; post-emergence stem and leaf treatment, prevention and control of annual broad-leaved weeds is better than pre-emergence soil treatment. In areas with high soil organic matter content, post-emergence shoot and leaf treatments are best. In order to reduce the amount of atrazine used to reduce the scorpion crop injury.
Isobuterin (Dingbuterrin, Glycyrrhiza) can effectively control a variety of annual grass weeds, broad-leaved weeds and some Cyperaceae weeds. Before sowing, the corn was sowed for soil treatment. The sandy soil, loam soil with 85% EC 270ml/mu, and clay soil with 350ml/mu were sprayed with water. Because Isobutanol is volatile, it must be mixed into the soil within 20 minutes after applying the mixed soil method.
Metolachlor (Dore) can effectively control annual grass weeds and some broadleaf weeds. Soil treatment before sowing and before sowing, preferably after sowing, with 72% Dole EC 100-200ml/mu, depending on the specific soil conditions, sandy soil to reduce the dosage, clay land To increase the amount of medication, soil with high organic matter content must also increase the dosage. If the weather is dry after application, the chemicals can be mixed into the 2-3 cm soil layer.
Alachlor can effectively control annual grass weeds and some broadleaf weeds. Soil treatment prior to sowing and before sowing, preferably after sowing, with 48% cable 250-400ml/mu, depending on the specific soil conditions. Sandy soil reduces dosage, clay ground To increase the amount of medication, soil with high organic matter content must also increase the dosage. After the application, if the weather is dry, the chemicals can be mixed into the 2-3cm soil layer, and irrigation can be done in places where conditions permit.
Acetochlor can effectively control annual grasses and broad-leaved weeds. Before sowing, before sowing, it is best to apply the pesticide immediately after sowing, and the amount of medication depends on the soil conditions. The content of soil organic matter in North China is below 6%, with 50% acetochlor EC 150-200ml/mu; soil organic matter content above 6%, and 50% acetochlor EC 200-270ml/mu. Pre-emergence application before sowing or after sowing, it is best to mix in 2-3cm soil after spraying in the north. In case of drought, where conditions permit, irrigation can be carried out. Covering the field with plastic film, the dosage can be reduced by about 30%.
Second, corn weed control and herbicide mixed technology Nicosulfuron (Yu Nong-le) can effectively control the grass, Setaria viridis, crabgrass, goosegrass, wild oats, roll stems, willow leaf, black Ear, Amaranthus retroflexus, Commelina edulis, Torreya grandis and Cyperus rotundus, Heterophyllous sedge, Fragile Melissa and other grasses, sedges, and broad-leafed stages are treated with stems and leaves, with 4% yam agricultural water agent 100ml/mu , Spray stems of water.
Dicamba (herbicide) can effectively control a wide variety of broad-leaved weeds. During the 3-4 leaf stage of the corn, stems and leaves were treated, and 48% of the herbicidal water-repellent agent 33-40 ml/mu was used to spray water on stems and leaves. The herbicides against corn are relatively safe and the correct application will not produce phytotoxicity. However, if the application is too late, the dosage is too large, and the operation is not standard, it will produce phytotoxicity.
Atrazine + Nicosulfuron (Atrazine + Jade Farm) The combination of the two can increase the herbicide spectrum and increase the weeding effect of some weeds. Mixed use can effectively control annual weeds, annual broad-leaved weeds and Cyperaceae weeds. As the amount of atrazine was reduced, the safety of post-crop crops was improved. The post-emergence and post-emergence treatment of corn seedlings and weeds at the 2nd to 4th leaf stage was carried out with 4% yam agricultural water agent 67ml/mu + 40% atrazine suspension agent 100ml/mu.
Soil organic matter has a strong adsorption effect on atrazine, when the soil organic matter content exceeds 6%, due to the large amount of drug is not economical, should be changed to post-emergence stem and leaf treatment or use other herbicides. Post-emergence stem and leaf treatment with 200-270ml/mu is appropriate.
In the desolate areas, atrazine is used in excess of 133g/mu, and it is impossible to grow sensitive crops such as wheat, soybeans and millet. Pre-emergence soil treatment, prevention and control of annual grass weeds is better than post-emergence stem and leaf treatment; post-emergence stem and leaf treatment, prevention and control of annual broad-leaved weeds is better than pre-emergence soil treatment. In areas with high soil organic matter content, post-emergence shoot and leaf treatments are best. In order to reduce the amount of atrazine used to reduce the scorpion crop injury.
