Bordeaux mixture is a common fungicide . It is widely used to control field crops, vegetables, fruit trees and cash crop diseases. It is most suitable for the application of pathogens before invading the host. Let's take a look at it. Bordeaux solution for copper-sensitive crops such as plum, peach, pear, cabbage, wheat, apple, soybean, etc. under humid and rainy conditions, due to the increased dissociation of copper and enhanced penetration of leaf surface, it is easy to cause phytotoxicity. Lime-sensitive crops such as Solanaceae, Amaranthus, Grape, Cucumber, Watermelon, etc. are susceptible to phytotoxicity under high temperature and dry conditions. Bordeaux mixture is an inorganic copper protective fungicide. When the copper sulfate and quicklime are respectively prepared in 1kg and the water is 100kg, it is called the equal amount of Bordeaux liquid. When the quicklime is doubled of copper sulfate, it is called double-type Bordeaux mixture; on the contrary, the amount of lime is copper sulfate. At /2, it is called a half-quantity Bordeaux mixture. Bordeaux mixture is a liquid containing a very small amount of blue granular suspension. Corrosive to metals. Low toxicity to warm-blooded animals. Compared with inorganic copper preparations such as copper sulfate, basic copper sulfate and king copper, it has good spreadability and adhesion, can form a film on the surface of plants, is not easily washed by rain, has a long residual effect, and is safe for crops.
