First, the order of pesticide mixing should be accurate. The order of foliar fertilizer and pesticides 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.
The second is to add water after adding water and make a second dilution. When mixing, you can add half a bucket of water to the sprayer, add the first pesticide and mix. Then, the remaining pesticide is diluted with a plastic bottle, diluted, poured into a sprayer, mixed, and so on.
The third is to spray immediately after dispensing. Many times, vegetable growers usually prepare pharmacy at home and then transport it to the shed for spraying. When the pharmacy has been prepared for a few hours. Although the drug solution does not respond 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 farmers do not know whether pesticides can be mixed, it is best to conduct a small area test first. Not only do you have to see if there is any reaction during the preparation, but also whether it will cause phytotoxicity after use.
