The role of Bordeaux mixture

Bordeaux mixture is a protective fungicide . The active ingredient is basic copper sulphate, which can effectively prevent spore germination, prevent infection of pathogens, and promote green color, strong growth and improve disease resistance of trees. The preparation has the characteristics of wide bactericidal spectrum, long duration, no resistance to bacteria, low toxicity to humans and animals, and is the longest bactericide in the application history. It is widely used to control a variety of diseases such as vegetables, fruit trees, cotton, hemp, etc. It is particularly effective for leaf diseases such as downy mildew and anthracnose, potato late blight.

Speaking of the role of Bordeaux mixture, let's first look at the mechanism of action of Bordeaux mixture:

Bordeaux mixture itself does not have a bactericidal effect. When it is sprayed on the surface of plants, it is adsorbed on the surface of the crop due to its adhesion. In the process of metabolism, plants secrete acidic liquids, and the acidic substances secreted by bacteria invading plant cells, so that a small amount of basic copper sulfate in Bordeaux mixture is converted into soluble copper sulfate, thereby producing a small amount of copper ions (Cu ²⁺ ), after Cu ²⁺ enters the pathogen cells, the proteins in the cells are coagulated. At the same time, Cu ²⁺ can also destroy an enzyme in its cells, thus preventing the metabolism in the bacteria from proceeding normally. Under the influence of these two effects, bacterial poisoning can be killed.

The role of Bordeaux mixture is mainly reflected in the following four aspects:
First, Bordeaux mixture is the most commonly used protective agent in orchards, and it plays an extremely important role in the prevention and control of fruit trees. Today, with the development of science and technology, although there are many kinds of medicines, there is no medicine to replace it. Although some pesticide manufacturers or sellers have to promote the efficacy of their own drugs, there is a promotion that can replace the Bordeaux mixture. However, it is not. Especially in the rainy years, the discs that do not spray the Bordeaux liquid tend to fall early, and the discs that spray 2-3 times of Bordeaux liquid generally do not fall early.
Second, the summer tree body spray problem. The apple tree is sprayed with a large amount of paper, and is kept white by adding an adhesive, etc., which can reflect sunlight, reduce the temperature variation of the tree body, and improve the photosynthetic efficiency.
Third, there are repellent effects on pests. After the Bordeaux liquid sprayed, the tree body was white, and the peach, leaf curling, and beetle were repelled. The pests did not lay eggs on the tree, thus achieving the purpose of prevention and control.
Fourth, the drug and fertilizer are homologous, each agent is also a kind of fertilizer, while the Bordeaux mixture is also sterilized, and the fruit tree is supplemented with calcium and copper.
