There are many weeds in corn fields, and there are 43 common ones, including 12 monocotyledonous weeds and 31 dicotyledonous weeds. Control weeds in corn fields and adopt chemical weeding methods to save labor, labor, and time. Now introduce 7 commonly used corn field chemical herbicides. 1. Atrazine, also known as Atrazine, is a 40% rubber suspension and is a broad-spectrum herbicide commonly used in corn fields. It is used before emergence after corn sowing, that is, atrazine is sprayed immediately after sowing of corn, and the dosage is 200-300 ml per 667 square meters. It should be noted that atrazine has a long duration in the soil, and if the amount of atrazine is too large, it can easily damage the sensitive crops (such as rapeseed). Therefore, weeds are commonly used to remove weeds. Maize 3 to 5 leaf stage, weed 2 to 3 leaf stage. 2. Acetochlor Acetochlor (50% EC) is the largest herbicide produced in China. It is used before emergence after corn sowing. The dosage is 150-200 ml per 667 square meters. The herbicide is safe for soybeans and peanuts and is therefore suitable for plots interwoven with corn, soybeans and peanuts. Acetochlor mainly controls 1 year old grass weeds and has poor control effect on dicotyledonous weeds. 3. Butachlor dosage form is 50%, 60% EC, used before emergence after corn sowing, the dosage is 667 square meters, 60% butachlor 125-150 ml or 50% butachlor 150-185 ml. Butachlor is safe for soybeans and peanuts, so it is suitable for plots of intercropping maize with soybeans and peanuts. 4. Bismuth water is a mixture of atrazine and acetochlor. It is used before emergence after corn sowing. The dosage is 200-300 ml per 667 square meters. It should be noted that B can not be used for land plots interwoven between maize and soybeans and peanuts. It can only be applied to plots of corn monoculture. 5. Kecaoling 45% suspoemulsion, a herbicide compounding agent successfully developed by the Weed Research Department of the Agriculture Department of Shandong Laiyang Agricultural College, is a new type, safe and highly effective herbicide for controlling the weed communities in corn fields. After years of field trials, it was proved that Kecuring can control all kinds of weeds in summer corn field once, and the weed control effect is over 90%, and the effective period is 60 days. The optimal period of use is 10-15 days before or after corn emergence, and 667 square meters of 200-250 ml. Before use, the chemical should be shaken well and shaken thoroughly. The agent should be mixed evenly in the sprayer and be evenly mixed with water. The amount of water should be 30-35 kg per 667 square meters. Use windless weather to prevent chemical liquids from floating on sensitive crops such as soybeans, peanuts, and cotton. 6. The generic name of the cable is Alachlor (43% EC), also known as grass is not green. The cable is a selective pre-emergence herbicide that can be absorbed by the young shoots of the plant, killing the weeds at the bud stage without unearthing. Before corn seedlings are sown, 150-300 ml per 667 square meters of water and 30-35 kg of water are sprayed evenly. The cable is safe for soybeans and is therefore suitable for chemical weeding on corn and soybean intercropping plots. 7. Shitian 33% EC is a broad-spectrum herbicide for dry field crops. It has a wide range of application, especially for a variety of mulching film crops. It can effectively control a variety of annual monocotyledonous and broad-leaved weeds. Long term, stable efficacy. Shi Tianbu applies to cotton, corn, vegetables, peanuts, sunflowers and so on.
