Foliar fertilizer and pesticides mixed five things to pay attention to

Ensure that the properties of the foliar fertilizers and pesticides after mixing are stable because the foliar fertilizers may chemically or physically react with the pesticides, affecting the effectiveness of pesticides or causing phytotoxicity. Even if the physical properties of the liquid medicine are good after mixing, a small-scale test must be performed first to see if it is prone to harm due to fertilizer and then applied on a large area.

The mixing order of the foliar fertilizer and the pesticide should pay attention to the general use of a sufficient amount of water to first mix with a single-agent liquid, and then use this liquid to dilute another single agent. 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 one by one. Each agent is added and mixed thoroughly and then the other is added.

When mixing, pay attention to the amount of water used in the water has a great impact on the liquid, the pH of the water, ion concentration, etc., will affect the effect. The water used for dispensing should be neutral water with low ion concentration, such as clean rain and river water.

Attention should be paid to the current drug solution. Although there is no adverse reaction at the time of dispensing, it is prone to produce slow reactions for a long time, so that the efficacy is lost or phytotoxicity is easily caused. For example, some pesticides are stable under weak alkaline conditions. However, we must also pay attention to the current use, if it is placed for a long time is also easy to fail.

Note that the acidity and alkalinity should also be tested to see if there is flocculation, sedimentation or discoloration, and bubbles after mixing. If the liquid has bad performance, it is not suitable for mixed application. Even if the physical properties of the liquid medicine are good after mixing, a small-scale test must be performed first to see if it is prone to harm due to fertilizer and then applied on a large area.
