In the winter shed, there are many diseases in the house and there are many spraying times. Many vegetable farmers reduce the number of shots and reduce labor intensity. Each spray is mixed with various pesticides. There are too many kinds of pesticides, and they are prone to problems when they are mixed. Special attention is required.
The sequence of pesticides to be mixed is exactly the order of mixing the foliar fertilizer and the pesticide. Usually, the order of the foliar fertilizer, the wettable powder, the suspension agent, the water agent, and the emulsifiable concentrate is added in order, and each mixture is mixed thoroughly and then added again. The next one.
Add water first and then add drugs. When the two dilutions are mixed, you can add half a barrel of water to the sprayer and mix the first pesticide. Then, the remaining pesticide is diluted with a plastic bottle, diluted, poured into a sprayer, mixed, and so on.
Spraying immediately after dispensing Many times, growers generally have good medicines at home and then transport them to the shed for spraying. More often than not, they are formulated for several hours. Although the drug solution does not respond at the time of the dispensing, it does not mean that it can be stored for a long time. Otherwise, it will easily produce a slow reaction and gradually reduce the efficacy of the drug.
