Corn weed control technology

1. The main weeds in the main weedy corn fields are: annual wild pheasant, goosegrass, green foxtail, teff, xanthium, alfalfa, alfalfa grass, purslane, and yellow wormwood; perennial Grasses, spiny vegetables, radicchio, bougainvillea and sedges. In the weeds of corn fields, the most harmful and hardest to control are the perennial weeds with underground rhizomes. Because its underground rhizomes have been cut off, they have the ability to regenerate; water peanuts, purslane, and grass weeds are also difficult to eliminate, and they are also very resilient, and it is better to treat broad-leaved annual weeds.

Second, control methods Corn weed control methods are artificial, animal husbandry weeding and chemical weeding in three ways. Due to the high temperature and high humidity season during corn growth, weeding by artificial and animal power is very difficult, and the weeding effect is not satisfactory. Because weeding is done manually and by animal power, if the grass is not transported out, it will quickly grow again. The method of chemical weeding is simple, easy to use, labor-saving and labor-saving. The cost is lower than that of manual weed control, and the weeding effect is also good. Generally it can reach more than 90%, and it can be controlled once, and it can maintain the entire growth period. Little grass. In addition, chemical weeding can reduce field operations injury, chemical weeding is generally sprayed after sowing, before emergence, no damage to seedlings. When animal husbandry forces are weeding, the phenomenon of injury and pressure seedlings often occurs because the animals are not straight or the animals do not go wrong. Herbicides commonly used in corn are atrazine, lanso, chlorin, acetochlor, weed-pass, dul, chlorotoluron. The best effect is atrazine, but since corn is generally in rotation with wheat, corn is inoculated after wheat is harvested, and wheat is sensitive to atrazine, overdose easily leads to wheat seedlings, so production will generally be a Terrain is mixed with other herbicides. Chemical weeding at different growth stages of corn should adopt different methods. Spraying herbicides on the soil surface before emergence of maize is generally conducted. 72% of 2,4-dibutyl butyl ester can be used 150-200 g; or 50% of Simazine WP, 50% of Atrazine can be used. Powder, spring corn spraying 400 grams per acre, summer corn spraying 150-200 grams per acre. For example, a dosage of 200 g/mu for green ryanosine and 200-300 g/dime for 25% of diural. After corn enters the jointing stage, it can use 72% 2,4-D Butyl Ester 50-70 grams per acre; or 80% 2,4-D sodium salt spray 75-100 grams per acre. Such as the use of aircraft spraying, add 3 to 4 kilograms of water per acre; using tractor-mounted spray, add 10 to 20 kilograms of water per acre; carrying a sprayer add 40 to 50 kilograms of water per acre. The effect of chemical herbicides is related to the water content of the soil surface. Soil wetting is a good herbicide, and soil drying is not as effective as chemical weed control. Therefore, when the soil moisture is not enough, do not spray hard after sowing. You can wait for the emergence of corn and wait for rain or irrigation before spraying. Chemical herbicides are generally toxic, so herbicides should be avoided as much as possible during the spraying process. After spraying, wash your hands, face, and change clothes with water.
