Add the appropriate amount of vinegar in the water to prepare the pesticide, neutralize the acid and alkali, the alkali in the water does not exist, and then prepare the pesticide to avoid the decomposition of the pesticide, so as to ensure that the pesticide plays its proper role. In practical application, the amount of vinegar can be adjusted according to the alkaline size of the well water. In areas where the well water is less alkaline (pH 7.2), the ratio of water to vinegar is 200:1 to 500:1; in areas where the well water is more alkaline, the ratio of water to vinegar is 160:1 to 200:1.
