2. Pesticide Bordeaux mixture is made of lime milk and copper sulfate aqueous solution in a certain proportion. This sky-blue viscous suspension pesticide for fruit trees and vegetables eliminates pests and diseases through the element of copper in it. During this period, not only the property of calcium hydroxide that can react with copper sulfate is used, but also the use of calcium hydroxide is slightly soluble in water to make the liquid medicine viscous, which is conducive to the adhesion of the liquid medicine on plant branches and leaves. In addition, calcium hydroxide reacts with carbon dioxide in the air to form calcium carbonate that is slightly soluble in water, which is also beneficial for the liquid to adhere to the surface of plants for a period of time without being washed away by rain.
