Mixed use of foliar fertilizers and pesticides
In the recent guidance of production in the countryside, many vegetable farmers have asked whether foliar fertilizers can be used in combination with pesticides. Now let's talk about this issue. Whether foliar fertilizers and pesticides can be mixed, according to the specific introduction of the drug, read the instructions carefully before mixing the chemicals. Because the nature of fertilizers and pesticides is different, if the mix is ​​unreasonable, the effects of using fertilizers and even fertilizers will be affected. harm. First of all, make sure that no chemical reaction occurs between the mixed foliar fertilizer and the pesticide. After mixing, if the physical properties of the liquid are good, a small-scale test must be conducted first to ensure that there is no large-scale use after the occurrence of fertilizer damage. Second, pay attention to the order of mixing the foliar fertilizers and pesticides. Generally, a sufficient amount of water is used first to prepare a single-agent liquid and then mixed together. It is not possible to mix the two drugs first, and then dilute with water so as to avoid adverse reactions and cause the active ingredients to be destroyed. When the foliar fertilizer is mixed, the order of mixing the foliar fertilizer and the pesticide is usually: the foliar fertilizer, the wettable powder, the suspension agent, the water agent, and the emulsifiable concentrate are added in order, and each one is immediately mixed thoroughly 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 pharmaceuticals, and water pH, ion concentration, etc. will affect the effect. Apply clean well water, rainwater, river water, etc. with water. Fourth, the liquid medicine should be used immediately. The liquid medicine should be used immediately. Because some liquid medicines do not have adverse reactions at the time of dispensing, they will slowly react for a long time and cause the loss of efficacy or phytotoxicity. Fifth, the mixed use of foliar fertilizers and pesticides is contraindicated. (1) Alkaline pesticides can not be mixed with ammonium nitrogen fertilizer and superphosphate, etc., otherwise it will cause loss of ammonia volatilization and reduce fertilizer efficiency. (2) Arsenic-containing pesticides should not be mixed with potassium salts and sodium salt fertilizers. Otherwise, soluble arsenic will be produced and phytotoxicity will occur. (3) Alkaline fertilizers such as ammonia, lime, and ash can not be mixed with pesticides, otherwise it will reduce the efficacy. (4) Chemical fertilizers cannot be mixed with microbial pesticides because chemical fertilizers are volatile and corrosive. Mixing them with microbial pesticides will kill microorganisms and reduce their effectiveness.
