What should be noted when using glyphosate for weed control in corn fields? Please give an introduction
Glyphosate is a systemic herbicide. When used for weed control in corn fields, if used improperly, it can cause damage to corn. There are mainly the following reasons:
First, there is a lack of understanding of the properties of glyphosate. Glyphosate is a systemic herbicide. After the glyphosate solution is absorbed by corn leaves, it not only damages the leaves that come into contact with the herbicide, but the entire plant will also be affected.
Second, spraying techniques are not standardized, and awareness of protecting corn is poor. Some people think that having a shield is enough and that there is no need to specifically protect the corn. In addition, some shields are of poor quality and do not provide strong protection for corn, which is also an important cause of herbicide damage to corn.
Third, in the middle and late stages of corn growth, the weeds in the field are older in leaf age, and some weeds grow tall, so the spray nozzles must inevitably be raised to apply the herbicide, which increases the spray width of the solution, making it easy for the lower leaves of corn to come into contact with the herbicide.
Fourth, when applying the herbicide in high-temperature weather and after application, corn will absorb some of the herbicide solution evaporated by the high temperature, thereby being affected to a certain extent or suffering aggravated herbicide damage. In short, when using glyphosate for weed control in corn fields, improper protection can easily lead to herbicide damage, 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 safer.
