Bringing Bordeaux liquid, I think most farmers are no strangers. Bordeaux mixture is a common fungicide. It has the characteristics of protection, low toxicity, etc. What are the specific effects of Bordeaux mixture? The following is a small series of pesticide nets . Get up and get to know it.
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 is a repellent effect on Bordeaux liquid 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.
