Anonymous users2024-02-03The components of Bordeaux liquid are: hydrated lime, copper sulfate, water. Bordeaux liquor is a suspension of copper sulphate, hydrated lime and water in a certain proportion.
The active ingredient in Bordeaux liquid is basic copper sulfate, which is a light blue flowing suspension with the chemical formula Cu2(OH)2SO4.
What is Bordeaux liquid.
Bordeaux liquor is an inorganic copper biocide, which is a protective biocide. Bordeaux solution inhibits spore germination or hyphal growth of pathogenic bacteria by releasing soluble copper ions. Bordeaux sap can effectively prevent the germination of spores, prevent the infection of pathogens, and can promote the strong green leaf color, grow robustly, and improve the disease resistance of the tree.
The preparation has the characteristics of wide bactericidal spectrum, long duration of effect, no resistance to pathogens, and low toxicity to humans and animals, and is a fungicide with the longest application history.
The principle of making Bordeaux liquid.
Cuso +Ca(OH) =Caso +Cu(OH) Ca(OH) +2CuSO=Caso +Cu (OH) SO4 ionic reaction equation Cu2++SO42-+Ca2++2(OH)-=Cu(OH)2 +CaSO4
When Cu(OH) is generated, there are no copper ions and the bactericidal effect is lost.

Anonymous users2024-02-02Bordeaux liquor is a colloidal suspension obtained by mixing lime, copper sulfate and water in a ratio of 1:1:10.
Bordeaux sap was used as a "poison" in the grape-growing Bordeaux region of France in the 19th century to prevent grapes from being eaten and sprayed on grape plants.
Bordeaux liquid can effectively prevent the germination of spores, prevent the infection of pathogens, improve the disease resistance of the tree, and has the characteristics of wide bactericidal spectrum, long duration of effect, no resistance to pathogens, low toxicity to humans and animals, etc., and is a fungicide with the longest application history. Bordeaux liquid is also a dual-purpose preparation of medicine and fertilizer, which can promote strong green leaf color, strong growth, and can also supplement calcium and copper for plants.

Anonymous users2024-02-01Inorganic copper biocide is called Bordeaux liquid.
Bordeaux liquid is a sky-blue gelatinous suspension liquid, which has the effect of preventing spores from germinating, preventing bacterial infection and sterilization. Originated in 1882 in Bordeaux, France, Bordeaux liquid is generally alkaline and has good adhesion properties, but the physical properties are destroyed for a long time, and it can be used or made into dehydrated Bordeaux powder, and then mixed with water when used.
The chemical composition of the active ingredient of Bordeaux liquid is CuSO4·XCU(OH)2·YCA(OH)2·ZH2O. Formulated with about 500 grams of copper sulphate, 500 grams of hydrated lime and 50 kilograms of water.

Anonymous users2024-01-31Bordeaux liquor is a plant bactericidal protective agent made of copper sulfate, calcium oxide (quicklime) and water, which has a good control effect on most fungal diseases and bacterial diseases, and does not produce resistance to long-term use.
1882 French AMjalldai discovered its bactericidal effect in the city of Bordeaux, hence the name Bordeaux liquid. It is a sky blue gelatinous suspension formulated from about 500 grams of copper sulfate, 500 grams of hydrated lime, and 50 kilograms of water.

Anonymous users2024-01-293 All Bordeaux solution is an excellent fungicide.
Bordeaux liquid has a history of more than 100 years in the world, with good protection performance, strong adhesion, stable liquid medicine, no pesticide damage, rain erosion resistance, low cost and other characteristics.
In particular, zinc-copper Bordeaux liquid, not only has a good disease prevention effect, but also has a nutritional effect, after using the lack of nutrients in George grapes, at the same time for the plant to supplement zinc, copper, calcium, strengthen the tree, enhance self-immunity, can prevent a variety of diseases of grapes, grape downy mildew, black pox, anthracnose, acid rot, etc., kill two birds with one stone.

Anonymous users2024-01-23Bordeaux liquid is not a solution, Bordeaux liquid is a suspension mixed with CuSO4 solution and Ca(OH)2 solution, the active ingredient is basic copper sulfate, which can effectively prevent the germination of spores, prevent the infection of pathogens, and can promote the leaf color to be thick and green, grow strong and sail, and improve the disease resistance of the tree.
Bordeaux liquid itself does not have a bactericidal effect, and when it is sprayed on the surface of the plant, it is adsorbed on the surface of the crop due to its adhesive properties. In the process of metabolism, plants will secrete acidic liquids, coupled with acidic substances secreted by bacteria when they invade plant cells, so that a small amount of basic copper sulfate in Bordeaux solution is converted into soluble copper sulfate, thus producing a small amount of copper ions (Cu), and after Cu enters the bacterial cells, the proteins in the cells are coagulated.

Growers know that spraying Bordeaux liquid is expensive, but it is worth it.
It's a meticulous job. Tie the sprinkler head to the bamboo pole, press the potion on, and spray it on the leaves of the pear tree, the leaves of the apple tree, and the leaves of the grapes. Spray it evenly, no more, no less.
If you spray too much, the water droplets of the potion will become a patch, and you can't hang it and it will flow; Spray less, it doesn't work. Spray the front and back of the leaves. It's not heavy, but when it's done, the eyes and neck are sour.
Why is it called "Bordeaux liquid" mud? - China's old fruit growers say that this foreign name is already very smooth. There's a story to this.
Bordeaux is a small town in France, out of the potato. One year, all the potatoes in France were stricken with late blight,—— which was so severe that the diseased fields were burned as if they had been burned, but the potatoes from Bordeaux were unharmed. Everyone, what is the reasoning behind this?
It turned out that there was a copper mine outside Bordeaux, and a small river flowed from the mine, and the riverbed was limestone. The water is blue and inedible, and the peasants use it to water the land. Could it be that this river keeps Bordeaux's potatoes disease-free?
So there was Bordeaux liquid in the world.
The old Chinese peasants now say the French name very easily.
Last year, a friend went to France, and when I asked him where he had been, he said proudly: Bordeaux!
I've also been to Bordeaux, in China.

1.Imagine a cube with a regular shape, submerged in water, its 6 faces are subject to the pressure of water, because its left and right sides, the front and rear sides of the surface under the water depth is the same, then the pressure of the water is also the same, the pressure is equal in size, the direction is opposite, balanced with each other, and the upper and lower sides are in different depths in the water, the pressure of the water is small, the pressure is also different, the lower surface is subjected to the upward pressure of the water f is greater than the upper surface by the pressure of the water f downward. The net force of the pressure on the object is the buoyant force of the liquid on the object. >>>More
