Calcium hydroxide can be used as an insecticide to eliminate pests and diseases in agriculture, which will be explained in detail as follows.

In agriculture, it is applied to reduce soil acidity and improve soil structure. The pesticide Bordeaux mixture is prepared by mixing lime milk and aqueous copper sulfate solution in a certain proportion. This sky-blue viscous suspension pesticide for fruit trees and vegetables kills pests and diseases relying on the copper element contained in it. It takes advantage not only of the property that calcium hydroxide can react with copper sulfate, but also the characteristic that calcium hydroxide is slightly soluble in water to make the liquid medicine viscous, which helps the liquid medicine adhere to the branches and leaves of plants. In addition, calcium hydroxide reacts with carbon dioxide in the air to form slightly soluble calcium carbonate, which also allows the liquid medicine to stick to plant surfaces for a period of time without being washed away by rainwater.
