The accurate, reasonable and scientific method of dilution of pesticides is an important condition for saving money, avoiding waste, and ensuring efficacy. The dilution methods for various formulations of pesticides are described below, so that farmers' friends can accurately take the dilution of pesticides.
First, the dilution method of powder pesticides: usually powder pesticides do not need to be diluted, but when the crop plants are tall and flourishing, in order to spray the limited chemicals evenly on the surface of the crops, a certain amount of filler (grass, etc.) can be added. ) Perform the dilution. When diluting, take a part of the filler, mix the required powder pesticide into the mixture, mix it repeatedly, and mix it until the required filler is added. In the process of dilution, you must pay attention to complete protection measures. A poisoning accident occurred.
Second, the wettable powder dilution method: Usually also take two-step formulation, that is, first with a small amount of water formulated into a thicker "mother" to fully stir, and then poured into the syrup bucket for the final dilution. Because if the quality of the wettable powder is not good, the powder particles often agglomerate together to form larger granules. If the granules are directly poured into the syrup bucket, the coarse granules will not be fully dispersed and will immediately sink to the bottom of the water. difficult. The problem to be noted in the two-step preparation method is that the amount of water used is equal to the total amount of water used, otherwise it will affect the concentration of the liquid to be formulated.
Third, the liquid pesticide dilution method: It depends on the amount of liquid dilution and the size of the drug activity. The amount of liquid used for prevention and control can be directly diluted near-line, that is, the required clear water can be contained in the ready-made pharmaceutical container. After that, the quantitative medicine is slowly poured into water and gently mixed with a small wooden stick to provide spray. Use, if you need to prepare more liquid medicine in a large area, you need to adopt a two-step method. The specific method is: first use a small amount of water, dilute the pesticide into the mother liquor, and then prepare it. The mother liquor is added to the prepared fresh water according to the dilution ratio and stirred until it is even.
