Glyphosate is one of the most commonly used herbicides . Many people feel that it has no effect after spraying glyphosate. They think that they may have bought fake glyphosate or the effect is not good. The pesticide Xiaobian thinks that it is not necessarily bought fake medicine. It may be caused by improper use of methods. How to effectively improve the efficacy of glyphosate is explained in the small series today. I hope that the following methods to improve the efficacy of glyphosate will help you:
First, choose the best medication period
For example, the use of glyphosate to control corn field weeds is best when the corn seedling height is 1.5 meters, the lower part has 2-3 old leaves, and the grass is up to 10 cm.
Second, we must pay attention to environmental conditions
As the temperature rises, the absorption of glyphosate by weeds will gradually increase, so when the temperature is high, the effect is better when the temperature is lower. In addition, the high relative humidity of the air can prolong the wetting time of the liquid on the surface of the plant, which is beneficial to the conduction of the drug. When the soil is dry and the water content is small, it is not conducive to the metabolism of the plant, which is not conducive to the conduction of the drug in the weeds, so the efficacy is also reduced.
Third, mix with other herbicides to pay attention to
Some farmers want to remove a variety of grasses. In order to save labor, other herbicides are added at will when using glyphosate, but the results are not good. Because some herbicides cannot be mixed with glyphosate, fast-acting herbicides such as metformin and paraquat cannot be mixed with glyphosate to avoid premature death on the grass and loss of glyphosate. The systemic absorption function reduces the killing effect of glyphosate on the root weed rhizomes.
Fourth, the application method is also very important
The method of using glyphosate to control weeds is critical because, in a certain concentration range, the higher the concentration, the finer the droplets of the sprayer, the more favorable the weed absorption; at the same concentration, the more the dosage The better the weeding effect.
You need to purchase glyphosate in China can buy pesticides net.
