1. 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. 2. 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. 3, mixed with other herbicides are particular about. 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. More pesticide knowledge , please pay attention to China Pesticide Network
PC Wire
PC wire is used in major construction projects as a means of increasing the strength of cast concrete components, ranging from railway track sleepers, ground stabilizing piles, floor beams and pipe systems. The process involves the continuous heating and stretching of a cold drawn high-carbon steel wire to produce a finished product with a much improved yield stress and greatly reduced load relaxation.
