How to improve the efficacy of glyphosate? Which methods are simple and easy to use? We also ask knowledgeable netizens to help introduce themGlyphosate is a common herbicide. During application, external factors affect how well it works, so Zhongdiwang has compiled methods for improving the efficacy of glyphosate, listed in detail below for netizens' reference.
Method One:The glyphosate solution must be translocated in large amounts to the underground rhizome tissues of the weeds to achieve a herbicidal effect. This requires the weeds to have relatively many leaves. If, before use, the weed area is small and photosynthesis is weak, the nutrients stored in the roots are translocated from below upward, and applying the herbicide at this time means very little of the solution is transported down into the roots, so it cannot kill the weeds; however, in the middle and late stages of weed growth, photosynthesis is strong and the photosynthates are translocated from top to bottom, so applying the herbicide at this time gives the best effect.
Therefore, the most important point in using glyphosate is to select the best time for application. For example, to control weeds in corn fields with glyphosate, the best time to apply is when the corn seedlings are 1.5 m tall, the lower part has 2-3 old residual leaves, and the weeds have reached a height of 10 cm.
Method Two:Within the range of 24-25 degrees, as the temperature rises, the amount of glyphosate absorbed by the weeds doubles, so applying the herbicide at high atmospheric temperature gives a better effect than at low temperature; high relative air humidity can prolong the time the glyphosate solution remains moist on the plant surface, which is favorable for the translocation of the herbicide; when the soil is dry and has low water content, it is unfavorable for plant metabolism, and therefore unfavorable for the translocation of the glyphosate solution in the weeds, so the efficacy also declines.
Method Three:Because some herbicides cannot be mixed with glyphosate, such as MCPA, paraquat, and other fast-acting herbicides, which cannot be mixed with glyphosate for use, lest the aboveground part of the weeds dies too early and loses its systemic translocation function for glyphosate, reducing glyphosate's killing effect on the underground weed rhizomes. However, adding some plant growth regulators and adjuvants to glyphosate can improve the control effect.
Method Four:The application method is crucial to glyphosate's control of weeds, because within a certain concentration range, the higher the concentration, the finer the sprayer droplets, which is favorable for absorption by the weeds. At the same concentration, the greater the amount used, the better the herbicidal effect.
Adding 0.1% washing powder to glyphosate, or adding 30 grams of diesel oil per mu, can enhance the herbicide's spreadability, permeability, and adhesion, improving the control effect.
