The article describes in detail copper sulfate: use in horticulture. Information on the rules for the preparation of solutions, methods of processing, safety measures is provided.

Briefly about copper sulfate, application

CuSO4 or copper sulfate in another way, is often used by gardeners as a preventive drug and a means to destroy various pathogens. Copper sulfate is able to fight various insects and viruses.
Copper sulfate looks like a blue crystalline powder. Does the substance react with oxygen for a long time, its color changes to gray and the crystals lose their beneficial properties. To regain lost qualities, you need to put the powder in water. It is a fungicide that is actively used in horticulture.
Important! Often on the packaging there is a chemical designation of the substance - CuSO4.

Copper sulfate: application subject to safety measures and what garden lovers fear

Subject to precautions, copper sulfate does not linger in the tissues and organs of plants. Often people believe that when copper sulfate enters the soil, it combines phosphorus particles. Some crops growing on soils with a high copper content, after treatment with copper sulfate, have an insufficient amount of phosphorus in the tissues. To renew the necessary phosphorus, it will be necessary to feed the plants with mineralized fertilizers.

Why is copper sulfate treatment carried out?

Due to not very good environmental conditions, plants can begin to suffer, and, of course, this is a big loss for every gardener.

Application due to unfavorable weather conditions.
Due to the changeable climate, the immunity of plants can decrease, which negatively affects their productivity and life. Also, due to low immunity, plants are more susceptible to various diseases and pest attacks. To maintain the immunity of plants, you need to carry out certain treatments on time. Perhaps the most budgetary tool for processing your site is copper sulfate.

Application due to good reaction with crops.
Copper sulfate reacts very well with plants. Sufficient copper content in the soil and inside the plant itself guarantees almost complete protection against diseases and pests.

Application due to peat soil.
Plantings that grow on peat or soils with a high sand content will suffer most from a lack of copper.

Recommendation! It is best to process fruit trees and shrubs during the spring and fall. Warm times are best, when the branches still or no longer have leaves.

Autumn processing with copper sulfate.
Autumn processing takes place after the trees and shrubs have thrown leaves, and in spring, when the first buds begin to form. Excessive amounts of copper can negatively affect the plant, so you need to know when to stop and not apply the solution more than twice a year.

Potential harmful effects.

The consequences of an excessive amount of copper in a plant can negatively affect both the planting and the person himself. Plants can have reduced immunity, and people can get burns.
Attention. For every ten square meters of land, no more than three grams of copper should be applied.

What else contains copper sulfate.

Burgundy liquid, cupronaft and Bordeaux mixture contains copper sulfate. Be very careful when applying these fertilizers.

Concentrations found among copper sulfate solutions.

Solutions that can burn out plants.

They contain copper sulfate in three percent and five percent concentration. For ten liters of water, respectively, you need from three hundred to five hundred grams of powder. This is the most potent solution, and it must be used with some caution and only in extreme cases. It can be used for the destruction of mold during construction work and for soil disinfection. It is not recommended to plant plants for more than one year on the soil on which the treatment with a highly concentrated preparation took place.

Preventive and therapeutic solutions.

The concentration in such solutions ranges from half a percent to one percent. Accordingly, ten liters require from fifty to one hundred grams of copper sulfite. The solution will help in the fight against fungal diseases and the destruction of pests. It can also be used to disinfect plant wounds through which infection is possible.

Copper sulfate: use as a top dressing

Copper sulphate is the basis of fertilizers. The concentration of such solutions is two hundredths or three hundredths. For ten liters of water, only two to three grams of active ingredient are needed.

Rules for the preparation of a solution of copper sulfate.

Solutions based on copper sulfate are prepared in two stages.

The first stage of cooking.
A primary solution is prepared from copper sulfate. To prepare it, you need a container that is not used as a dish from which to eat. One hundred grams of copper sulfate is dissolved in a liter of water. The water temperature must be about sixty degrees Celsius for the powder to dissolve successfully. Until a homogeneous mass is obtained, the solution must be stirred. At the exit, a solution with ten percent copper sulfate content is obtained, it is not suitable for use on sites. The resulting solution must be diluted to a maximum concentration of one and a half percent.

The second stage of cooking.
How to dilute the stock solution to the concentration you need? In addition to the resulting mixture, the dishes must be added about ten liters of water. In order for the treatment of plants to be correct, they should be puffed out of a spray bottle.
How to apply copper sulfate in the spring?
It is recommended to process shrubs and trees in the spring. Plants will need copper during the flowering period. At this moment, the tissues and organs of the plant are most active.

Copper sulfate: application and its effectiveness

Processing before the onset of heat is several times more effective than processing in the autumn. During the fruiting period, plants will need many different trace elements. A solution of copper sulfate can burn flowers, leaves, as well as the fruits of plants, therefore, it is not recommended to process them. To protect yourself from burns, it is best to wear a protective suit or at least gloves. The solution contains a small percentage of sulfuric acid, but it can negatively affect human health.
Advice.It is recommended to alternate preparations containing iron and copper sulfate.

How it is processed.

Treatment with solutions of copper sulfate, trees and shrubs occurs through spraying branches and soil. The solution is not stored for a long time, therefore it must be prepared immediately before use. The solution is best used as a prophylaxis on plants that have not yet been infected with anything.

Treatment for the destruction of fungal spores.
To remove fungi from the soil, you can use a solution of copper sulfate as a fertilizer. What processing is useful before planting onions, carrots, radishes and their various vegetable crops.

Processing of potato tubers.
To process potato tubers before planting, you can use a copper sulfate solution, which has a concentration of two tenths of a percent. Such an operation will help prevent late blight.

Consequences of processing.

After treatment with copper sulfate, not only the immunity of the plant improves, but also in the case of potato tubers, the quality of the crop improves. The amount of starch and sucrose increases. It is generally accepted that tomatoes and potatoes are the most susceptible crops to fungi, so copper sulfate can help a lot. In the case of growing these crops, processing with copper sulfate is simply necessary.

Copper sulfate: use in preventive measures.

To protect future plants from possible diseases and possible pest attacks, the seeds are often placed in a copper sulfate solution before planting. Scientists believe that such prophylaxis can be dangerous for humans, copper may not be in time, get out of plantings and may not dissolve in the ground.
Use of CuSO4 against certain diseases.
Preventive treatment with copper sulfate of trees bearing fruits such as: 1) plums; 2) cherries; 3) cherry plum; 4) pear; 5) apple tree; 6) quince, produced by a solution of copper sulfate with a concentration of one percent. On average, it will take five liters of water to process one unit of wood. What treatment will help prevent diseases such as: 1) coccomycosis, 2) various rot, 3) fungi and 4) drying.

The use of copper sulfate in the fight against anthracnose.
To avoid contamination of the gooseberry, currant and barberry with anthracnose and septoria, you need to treat the plants with a semi-percent solution of copper sulfate. Processing is carried out at the rate of one and a half liters of the mixture for each bush.

The use of copper sulfate in the fight against powdery mildew, rust or various other fungal diseases.
To avoid contamination of the rose with powdery mildew, rust or various other fungal diseases, you need to treat it with a half-percent solution of copper sulfate. One rose will also require one and a half liters of the mixture.

Use of copper sulfate for disinfection purposes.
To disinfect the whiskers of strawberries, you can use a solution with a concentration of two hundredths of a percent of copper sulfate. The mustache must be placed in it, then pulled out and rinsed well.

The use of copper sulfate in the fight against fusarium.
A solution with a concentration of four hundredths of a percent, suitable for processing onions and garlic from diseases such as fusarium. Soak the onions for one hundred and twenty minutes.

How is the use of the solution and the age of the trees related?

There are several cases.

First case.
Twenty hundred milliliters of solution is suitable for a tree that is no more than three years old.

Second case.
Thirty hundred milliliters is fine for a slightly older tree that is four years old.

Third case.
For six-year-old trees, you can use up to forty hundred milliliters of solution.

Fourth case.
Five hundred milliliters of solution is used for trees that are more than six years old.

Safety measures when working with copper sulfate.

Is it forbidden to process any plants when there is a strong wind outside? There are several guidelines.

First recommendation.
The best time is when the sun's rays have not yet hit the plants directly, it can be either morning or evening.

Second recommendation.
For the solution to work, you can not process the plants after rain, the leaves must be completely dry. If you need to process on wet leaves, you can add a substance to the solution that will help fix the concentrate on the shoots.

Third recommendation.
The concentration of the solution cannot be more than five percent. A high concentration can not only damage plants, but also harm the environment.

Fourth recommendation.
When the plants are in the flowering period, treatment is strictly prohibited, it may harm the plants.

Fifth recommendation.
After processing the container from which the spraying was carried out, it is urgent to wash it.

Sixth recommendation.
In order to avoid the spread of crystals into groundwater, which can lead to dangerous consequences, the powder scattered inadvertently must be buried away from the place of possible occurrence of groundwater.

Copper sulfate: application and is there a danger to humans

The answer to this question is unequivocally: yes. Several facts.

First fact.

It is important to remember that fifty milliliters is a lethal dose for any person!

Second fact.
With direct contact, copper sulfate can instantly be absorbed into the skin, this can lead to irreversible consequences, therefore, a special suit is required when processing trees and other plants. Do not allow copper sulfate to get into your eyes or mouth.

Third fact.
You can go blind if the sulphate gets in your eyes. The substance itself is not flammable, but the products released during combustion are dangerous to human life in the life of plants and the environment.

Copper sulfate application in summer and autumn periods

There are several guidelines.

First recommendation.
Since scientists do not recommend processing plants when the outside temperature is more than thirty degrees, it is better to refrain from processing in the summer. It can be processed only in extreme cases, if the sprouts have signs of a lack of such an element as magnesium, namely: slow growth, chlorosis, killing of the shoots at the top.

Second recommendation.
In summer, tomatoes can suffer from various types of rot, and potatoes can get sick with late blight, cabbage can get sick with a black leg. To determine the state of your plants, you need to check the following: whether black rot has appeared on the cabbage and whether there are enough shoots and flowers on the tomatoes.

Third recommendation.
To save the crop, you can use a solution with a concentration of two tenths of a percent of copper sulfate.

Fourth recommendation.
In order for the dangerous substance to have time to leave the fruits, it is necessary to carry out the processing procedure exclusively more than a month before the direct collection of the fruits.

Fifth recommendation.
In the fall, you can also carry out preventive treatment of trees, this should be done only after the leaves on the trees have fallen off. This is necessary so that the plants do not have any damage.

Sixth recommendation.
Can autumn processing help your trees avoid attacks from various insects, as well as infestation with various diseases? Since pests are chosen to survive the winter, discarded leaves of trees, they should also be treated with a solution of copper sulfate.

Conclusion

Most importantly, remember copper sulfate - at least an effective remedy to fight almost everything. It is very dangerous, so be sure to follow the instructions and follow the safety rules.
