Cornfield can be weeded according to public opinion
Normal cultivation conditions and good soil moisture corn field weeding method
Generally, the agricultural production conditions are better, the water conditions are better, the sensation is better, and the past few herbicides or herbicides have been used. The main weeds in the field are crabgrass, foxtail, alfalfa and alfalfa. Etc., the herbicide can be compounded with acetaminophen, butyl hydrazine, and mepyridamidine before the seeding of the corn. This type of herbicide is mainly absorbed by buds and can effectively prevent annual grass weeds and broadleaf weeds. Although this type of herbicide has higher requirements for moisture, and the effect of weeding is poor, however, this type of herbicide is more resistant to rain and is more effective in weeding in the rainy years.
Cornfield weed control method in drought conditions
In general, corn is poorly plucked during corn sowing. Weed control in corn fields has become a problem in production. The herbicidal effect of conventional herbicides is declining. Therefore, paraquat herbicides such as paraquat are often applied in the middle and late stages of corn. When the herbicide is selected before the seeding of the corn, the herbicide which can absorb the roots, stems and leaves and kill the larger weeds should be used as much as possible. Whenever possible, increase the amount of water during application to allow the agent to spray onto the soil surface. It is also possible to use a compound herbicide such as acetamidine, isopropyl hydrazine, mepyridamole or acetophenone which is commonly used in the market. The herbicides are mainly absorbed by buds, roots and stems and leaves, which can effectively prevent annual grass weeds and broadleaf weeds, not only have better closed weeding effect, but also have better anti-weed seedling effect.
