Can fertilizers and pesticides be mixed? Foliar fertilizers and pesticides should be mixed. The question about whether foliar fertilizers and pesticides can be mixed should be based on the specific introduction of the drugs. You should read the instructions carefully before mixing the medicines. In fact, the properties of various fertilizers and pesticides will be different. If the mixture is unreasonable, it will affect the effect of using fertilizers and medicines, and even produce fertilizers and phytotoxics.

Matters needing attention when mixing foliar fertilizer with pesticides

Make sure that the shape of the foliar fertilizer and pesticide is stable 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 liquid are good after mixing, it is necessary to carry out a small-scale test to see if there is any damage or phytotoxicity, and then use it in a large area.

Pay attention to the order of mixing foliar fertilizers and pesticides. 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.

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.

Pay attention to the current use. Although the drug solution has no adverse reaction at the time of just matching, 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.

Taboo use of pesticides mixed with pesticides

Alkaline pesticides cannot be mixed with ammonium fertilizers such as ammonium nitrogen fertilizer and superphosphate, otherwise the ammonia will be lost and the fertilizer efficiency will be reduced. Arsenic-containing pesticides cannot be mixed with potassium salts or sodium salt fertilizers, otherwise soluble arsenic will be produced and phytotoxicity will occur.

Alkaline fertilizers such as ammonia, lime, and plant ash cannot be mixed with pesticides such as pesticides, otherwise the efficacy will be reduced. 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, green worms, etc., which are easy to kill microorganisms and reduce the efficacy.
