What should we pay attention to when using glyphosate to weed in corn fields? Please introduce glyphosate is an internal herbicide, when used in corn field, if it is not used properly, it will cause harm to corn, mainly for the following reasons: first, there is a lack of understanding of the performance of glyphosate. Glyphosate is an internal herbicide. After glyphosate is absorbed by corn leaves, not only the medicine leaves will be damaged, but the whole plant will be affected. Second, the operation of spraying technology is not standard, and the awareness of corn protection is poor, so it is considered that there is a protective shield, and there is no need to protect corn. In addition, the quality of some shields is poor, and the protective effect on corn is not strong, which is also an important cause of drug damage to corn. Third, in the middle and later stage of maize growth, the leaf age of weeds in the field is older, and some weeds grow higher, so it is necessary to raise the spray head and increase the spray amplitude of the liquid, and the lower leaves of corn are easy to be sprayed. Fourth, during and after the use of drugs in high temperature weather, corn will absorb part of the liquid evaporated at high temperature, which will be affected or aggravated the drug damage. in short, the use of glyphosate weeding in corn fields is prone to drug damage if the protection is not in place, so it must be used with caution. It is safer to choose contagious paraquat for weeding in the middle and later stage of corn growth.
