First, to ensure the shape of the foliar fertilizer and pesticides after mixing This is because foliar fertilizer may chemically or physically react with pesticides, affecting the effectiveness of pesticides or causing phytotoxicity. If the liquid has poor performance, it is not suitable for mixed use. Even if the physical properties of the drug solution are good after mixing, it is necessary to carry out a small-scale test first to see if it is prone to damage and phytotoxicity, and then use it in a large area. Second, the order of mixing foliar fertilizers and pesticides should pay attention to Generally, a sufficient amount of water is first prepared with a single dose of the drug solution, and then the other solution is diluted with the solution; instead, the two single agents may not be mixed first, and then diluted with water to avoid adverse reactions, resulting in effective Destruction of ingredients and deterioration of physical properties. When foliar fertilizer is mixed, the order of foliar fertilizer and pesticide is usually: foliar fertilizer, wettable powder, suspending agent, water agent, and emulsifiable oil are added in sequence, and each one is added, then fully stirred and mixed, and then the next one is added. . Third, pay attention to the use of "water" when mixing Water has a great influence on the liquid medicine, and the pH and ion concentration of the water will affect the effect. It is better to use medicinal water with neutral water with low ion concentration, such as clean rain water and river water. Fourth, pay attention to the current use Although the drug solution has no adverse reaction at the time of the formulation, it is easy to produce a slow reaction for a long time, which may result in loss of efficacy or susceptibility to phytotoxicity. If some pesticides are stable under weak alkaline conditions, they should also be used immediately. If they are placed for a long time, they will be ineffective. Several taboos for the use of foliar fertilizers and pesticides 1. Alkaline pesticides cannot be mixed with ammonium fertilizers such as ammonium nitrogen fertilizer and superphosphate, otherwise the ammonia volatilization loss will be reduced, and the fertilizer efficiency will be reduced; 2. The pesticide containing arsenic cannot be mixed with potassium salt or sodium salt fertilizer, otherwise it will produce soluble arsenic and cause phytotoxicity; 3, alkaline fertilizers such as ammonia, lime, grass ash, etc. can not be mixed with pesticides and other pesticides, otherwise it will reduce the efficacy; 4. Chemical fertilizers cannot be mixed with microbial pesticides. Because chemical fertilizers are volatile and corrosive, they can be mixed with microbial pesticides such as acaricidal bacteria and green worms to easily kill microorganisms and reduce control effects.
