First, the order of pesticide mixing should be accurate.
The order of mixing the micro-fertilizer with the pesticide is usually: foliar fertilizer, wettable powder, suspending agent, water agent, and emulsifiable oil are added in sequence, and each of them is mixed well, and then the next one is added.
The second is to add water after adding water and make a second dilution.
The compounding of pesticides is not simply a matter of pairing together. When mixing, you can first add half a bucket of water to the container, add the first pesticide and mix;
The third is to spray immediately after dispensing.
Although the drug solution does not react when it is just dispensed, it does not mean that it can be left for a long time, otherwise it will easily produce a slow reaction and gradually reduce the drug effect.
In addition, when it is not known whether the pesticide can be mixed, if it is not possible to determine whether it is possible to mix, try not to mix it, or perform a small-area test first. If a reaction occurs or delamination occurs, mixing cannot be performed.
