Copper hydroxide copper chloride, the pH is mostly neutral.
The quinone ketone is an acid, and the copper next to the gold word is alkaline.
Large manufacturers import complex copper, mixed pesticides can be used.
Pesticide compounding principle 2
Regulators and foliar fertilizers, acid and alkali ingredients do not understand,
What to do if the acid and alkali are not divided, the mixed drug must be after the first,
First, the leaf fertilizer is mixed with water to make the alkalinity neutral.
Then pour the acidic drug, and the current effect is good.
