All my shirts turned light blue after a summer of Bordeaux spray. Copper sulfate, lime, plus a certain proportion of water, this is the Bordeaux mixture. The Bordeaux mixture is beautiful and has a sky blue color. In the past, there was a kind of light blue indanshilin cloth, which was that color. It was a pesticide for the housekeeping of an orchard. An orchard is not an orchard without a spray of Bordeaux mixture. Bordeaux mixture prevents diseases and ensures a good harvest of fruit. Fruit farmers know that although Bordeaux mixture is expensive, it is worth it. It's a delicate job. Tie the nozzle to the bamboo pole, press the potion on it, and spray it on the leaves of fruit trees, apple leaves and grape leaves. Spray very evenly, not much, not much. If you spray too much, the water droplets of the potion will stick to one piece, and it will not hang and flow; if you spray less, it will not work. Spray the front and back of the leaves. This work is not heavy, but after it is done, the eyes and neck are all sore. I'm a pro at spraying Bordeaux mixture. Everyone asked me to sum up my experience. I said: 1. I can't do heavy work, but I can do it; 2. I think this work is poetic. Why is it called "Bordeaux liquid" mud? ——The old Chinese fruit grower said that this foreign name is very easy to say. There is a story here.

Bordeaux is a small town in France that produces potatoes. One year, all the potatoes in France got late blight. Late blight was so severe that the diseased potato fields burned like fire, but the potatoes in Bordeaux were safe. Guys, what's the point of this? It turned out that there was a copper mine outside the city of Bordeaux. There was a small river flowing out of the mine, and the riverbed was limestone. This blue water is inedible, and farmers use it to water the land. Could it be this river that keeps Bordeaux's potatoes free from disease? So the world has Bordeaux mixture. Old Chinese farmers now say the French name very smoothly. Last year, a friend went to France. I asked him where he had been, and he said proudly: Bordeaux! I have also been to Bordeaux, in China. 2 Organochlorine pesticides, the chemical name is bis-p-chlorophenyl trichloroethane.
