Glyphosate is a systemic herbicide. When used for weed control in corn fields, if used improperly, it can cause harm to corn, mainly for the following reasons:
First, a lack of understanding of the properties of glyphosate. Glyphosate is a systemic herbicide. After the glyphosate solution is absorbed by corn leaves, not only the leaves that receive the spray are damaged, but the entire plant is affected.
Second, spraying techniques are not standardized, and awareness of protecting corn is poor. Some people think that having a spray shield is enough and that there is no need to specially protect the corn. In addition, some spray shields are of poor quality and provide weak protection for corn, which is also an important cause of corn phytotoxicity.
Third, in the middle and late stages of corn growth, the weeds in the field have a relatively large leaf age. Some weeds grow taller, so the nozzle must inevitably be raised to spray, which increases the spray swath of the solution, and the lower leaves of the corn are likely to receive the chemical.
Fourth, when applying the chemical in high-temperature weather and after application, corn will absorb part of the solution evaporated by the high temperature, thereby being affected to a certain extent or suffering aggravated phytotoxicity. In short, when using glyphosate for weed control in corn fields, inadequate protection can easily lead to phytotoxicity, so it must be used cautiously. For weed control in the middle and late stages of corn growth, choosing the contact herbicide paraquat will be somewhat safer.
