Instructions for use of Bordeaux liquid (mixture). Bordeaux mixture (100 g) Bordeaux liquid 100 g instructions

Experienced summer residents use many drugs, wanting to get rid of diseases and pests in their area. One such remedy is Bordeaux liquid. Although the remedy has been around for a long time, it is still widely used today. The fungicidal properties of the drug were discovered in the 19th century. Initially, the Bordeaux mixture was used to process vineyards, and then began to be used for other crops.

Bordeaux liquid is an effective and inexpensive remedy for the treatment and prevention of diseases of horticultural and horticultural crops. The popularity of the drug is due to the availability of ingredients and the ease of preparing the solution at home.

Scope of the product and its composition

Bordeaux liquid consists of slaked lime. The drug is obtained by adding copper sulfate to a liquid solution of calcium hydroxide. When the components interact with each other, copper sulfate is formed, which kills harmful microorganisms.

The tool is used to combat fungal infections and pests. Bordeaux liquid in horticulture copes with many diseases that affect the leaves and bark of trees. Fruit and berry plants after using the product actively bear fruit, and coniferous trees grow much faster. The use of Bordeaux mixture in the fall is necessary in order to maintain plant immunity in the winter.

The drug has found wide application in the fight against such diseases:

• septoria, anthracnose and peronosporosis (cucumbers);
• mildew (grapes);
• scab, powdery mildew, rust, fruit rot (fruit and berry crops);
• late blight and macrosporiosis (potatoes and tomatoes);
• spotting (raspberries and strawberries).

On the shelves of garden stores you can buy a ready-made concentrated solution that needs to be diluted with water. It is packaged in bottles (0.5 l) and bottles (100 ml). But it's better to make your own. Preparation of Bordeaux liquid does not take much time and does not require special skills. Do not neglect safety measures - you should wear a protective suit, gloves and a respirator. It is necessary to allocate separate containers for the solution, which will not be subsequently used for other needs. The rest of the mixture must be disposed of.

It is necessary to prepare the composition before use. If the work needs to be transferred to the next day, 20 g of sugar should be added to the mixture. So the solution will not lose its properties.

Often 1 or 3% solutions are used. To prepare a 1% mixture, you need:

1. Take two containers made of glass or clay (metal is prohibited). Their volume must be at least 10 liters.
2. Dilute 150 g in one liter of water. Gradually add 4 liters of water.
3. In another container, mix 100 g of copper sulfate and 2 liters of hot water. After the mixture has cooled, add 3 liters of cold water.
4. Mix both compositions well.
5. Add copper sulfate to the lime in a thin stream (not vice versa). Stir the resulting Bordeaux mixture solution.

Preparation of a solution of 3% concentration is similar to the previous one. It is only necessary to increase the amount of dry ingredients and take 0.3 kg of copper sulfate and 0.45 kg of lime.

The instructions for use of the Bordeaux mixture indicate that it cannot be mixed with other products and used simultaneously with other fungicides.

Treatment of trees with the drug is carried out in the spring and autumn periods.

Spring spend preventive spraying. It is allowed to use a solution of 3% concentration when the buds are swollen or have just begun to bloom. If the tree already has leaves, a 1% solution should be used.

In autumn, treatment is carried out only with a 3% solution. This is due to the fact that the foliage has already fallen and there is no risk of burns. The use of Bordeaux liquid in gardening in the fall will help protect fruit trees from fungi: pear, cherry, apple, plum, quince, apricot.

Bordeaux liquid is widely used for the following crops:

The main factor in the preparation of the solution is the strict observance of the dosages of the components. With a low concentration of them, the spraying procedure will not give an effect and will not relieve the disease. By adding more substance, you can burn the roots or even the death of the plant.

Among the time-tested drugs that effectively protect plants is the Bordeaux mixture. Its development dates back to the end of the 19th century, when the fungicidal effect of an aqueous solution of calcium hydroxide and copper sulfate was discovered.

Initially, the drug was used to treat vineyards, and later began to be used for spraying other green spaces.

When to use?

Bordeaux liquid in horticulture helps to effectively deal with most pathogenic lesions on the bark and leaves. In fruit and berry crops, after processing, a greater number of fruits ripen, and deciduous and coniferous species significantly intensify their growth. In places where the bark is removed and on saw cuts of branches treated with Bordeaux mixture, rot crusts and darkened areas of wood will not form.

The mixture should be used with caution, since copper compounds are toxic to humans. Processing of fruit and berry trees is recommended 2-4 weeks before harvest.

This improves the quality and shelf life of fruits while reducing the residual concentration of copper on their surface. There is still controversy regarding the advisability of applying the composition at the dacha during the growing season, since the components of the drug can get on earlier fruit-bearing trees or shrubs.

Bordeaux liquid can lead to the appearance of a mesh structure of fruits and a change in their size. This effect is especially noticeable on cherries. A win-win option is to process trees before bud break. During this period, the mixture destroys most of the microorganisms at the initial stage. Do not confuse liquids for early gardening and those used during the growing season. A high concentration of active ingredients from the first 3% solution will adversely affect the development of a plant that has already thrown out its leaves. For the treatment of green plants, a 1% solution is used.

The composition and principle of action of the drug

The finished mixture is an aqueous solution of calcium hydroxide and calcium sulfate containing suspended copper hydroxide. The classic formulation of the drug includes three initial components - copper sulfate, quicklime and water. The concentration of the solution is understood as the content of the initially taken copper sulphate based on the final aqueous mixture.

The mechanism of action of Bordeaux fluid is the effect of residual copper ions on pests and fungi, which occurs at the cellular level. The mixture is effective not only in the treatment of shrubs and trees, but also flowers with affected inflorescences. There is a repellent effect of the composition on many harmful insects, which are repelled by the presence of the drug from damage to the plant.

A solution of pure copper sulfate would be much more effective if it did not destroy the plant. Calcium compounds play the role of a binding component, neutralizing the negative effect of copper to an acceptable level.

For humans, the Bordeaux mixture is harmful. The main routes of its entry into the body are:

• swallowing causes the most dangerous poisoning, which can occur after working with the drug or eating contaminated fruits. Treatment consists in gastric lavage, ingestion of protein and saline solutions, as well as cardiac drugs;
• inhalation of aerosols causes a fever that lasts 2-3 days and is accompanied by bloating, tachycardia and epistaxis.

If you suspect copper poisoning, you should call a doctor who will adjust the treatment and prescribe important stimulant drugs.

How to prepare a mixture at home without harm to health?

Preventing poisoning with a mixture is quite simple if you follow the general recommendations:

• use a respirator, gloves, headgear and protective outer clothing when preparing and spraying the drug;
• do not smoke, drink or eat between sprays;
• do not spray the mixture in close proximity to fruits and vegetables that will be harvested within 2-3 weeks;
• always rinse crop with water before use.

Keep in mind that during the spraying process, individual portions of the aerosol are spread over tens of meters. The result may be the ingress of substances to trees and shrubs remote from the place of processing.

Preparation of liquid at home

The scheme for mixing the components and obtaining the finished composition consists of several stages:

• initial weights of copper sulphate and quicklime are dissolved with stirring in a small amount of hot water. A separate container is taken for each solution. Lime slaking is not carried out in plastic buckets, since they can melt, and metal containers are not suitable for dissolving copper sulfate and storing Bordeaux mixture;
• both solutions are diluted with water to a volume of 5 liters, after which they are mixed;
• a solution of copper sulphate is poured in a thin stream into a continuously stirred solution of lime;
• the finished mixture is an opaque blue suspension. Its suitability for plant treatment should be checked by measuring the pH with litmus paper. If an acidic environment is detected, a small amount of lime mortar must be added to the Bordeaux liquid. The readiness of the drug is indicated by a weak alkaline or neutral environment.

The colors of the litmus indicator: in a neutral environment - does not change color (yellow paper), in an acidic environment - acquires a crimson hue (some mistakenly consider it red), in an alkaline environment - shows a blue coloration.

Component ratios (for a final volume of 10 l):

• copper sulfate - 100 g (1% solution) or 300 g (3% solution);
• quicklime - 100 g (1% solution) or 300–500 g (3% solution).

After preparation, the drug should be used immediately (do not insist), until the fine particles of copper hydroxide have combined into larger conglomerates. Periodic stirring allows you to maintain the dispersed state of the solution. Long-term storage causes hydroxide particles to stick together and precipitate, which will clog the sprayer nozzle. To keep the mixture for use for a couple of days, 5-10 g of sugar is added to it.

The process of preparing and using the liquid, see the video:

It will cost less to buy the ingredients for the Bordeaux mixture separately. A ready-made kit, including all components and litmus paper, is simpler, but more expensive.

Application features, dosage and consumption

The drug suspension is applied to the surface of plants in early spring and summer by spraying. The finished solution is poured into a tank, which is then pressurized (manually or from a carbon dioxide cylinder). Spray the mixture evenly on trees and shrubs, trying to get the liquid on all sides of the leaves and branches.

Features of using the tool:

• the composition should be sprayed carefully, avoiding spills on yourself and on the ground;
• before work it is necessary to make sure that there are no people without protective clothing (especially children) and animals in the spraying area;
• do not carry out work with a high probability of precipitation;
• application should be carried out strictly in the wind.

The number of treatments is:

• before the appearance of the kidneys - 1 (3% solution);
• during the growing season - 3-4 (1% solution);
• frequency of treatment (liquid validity) - 10-14 days.

Mix consumption:

• for trees (fruit and berry, deciduous and coniferous) and large shrubs - 15–20 liters per 100 m 2;
• for medium shrubs and grapes - 10–15 liters per 100 m 2;
• for small bushes (strawberries, potatoes) - 5–10 liters per 100 m 2.

Large trees that have external signs of fungus damage can be sprayed with a 1% solution of the mixture at the rate of 10-15 liters per tree.

The liquid remains an effective and cheap drug for the treatment and prevention of diseases of green spaces. Its widespread use in horticulture is facilitated by the availability of components and the ease of self-preparation. The versatility of the product allows for the joint processing of most plants and contributes to the overall improvement of the site.

Bordeaux liquid is a tool familiar to most gardeners and gardeners, it is actively used to combat and prevent fungal diseases of crops. But for beginners, the use of Bordeaux liquid is scary. This fear is rooted in ignorance and lack of experience. In order for the use of Bordeaux liquid to benefit the plants and not harm, it is necessary to properly prepare the solution, follow the proportions and rules for processing the garden. Read the instructions for using Bordeaux liquid in this article.

What is Bordeaux liquid

Bordeaux liquid is a solution that includes copper sulfate (chemical element copper sulfate, a powder with a bright blue tint) and slaked lime. Without knowing the composition of the Bordeaux liquid, inexperienced gardeners come to the conclusion that the treatment of crops with Bordeaux liquid is equated to dangerous chemical spraying. But in fact, the main ingredient of the solution, copper, is a trace element, without which the development of culture will not occur. Plants grown on soils poor in copper lag behind in development and growth, suffer from chlorosis, and are very rarely able to produce crops. In horticulture, a 3% and 1% solution of Bordeaux liquid is used; for the convenience of its preparation, packaging packages of 300 g and 100 g of copper sulphate are available for sale, respectively. To properly prepare a solution of Bordeaux liquid, follow the instructions given on the package with the product. An indicator of a properly prepared solution will be litmus paper. Checking the pH of the liquid should show a neutral or slightly alkaline reaction. Add more milk of lime if necessary. Prepare the solution for one use only, the liquid is not subject to storage.

Pros and cons of Bordeaux liquid

Let us consider in more detail the advantages of Bordeaux liquid.

• The solution quickly reacts with the leaves and shoots of the plant. You can not be afraid of rain and watering, the solution is not so easy to wash off the sheet.
• The terms of protection after processing are approximately one month. True, it is important to know that the quality of the purchased ingredients directly affects the duration of the protective functions. Claims to lime are especially common, buy powder in quality stores to be sure that there are no extra impurities in lime.
• The versatility of Bordeaux liquid is known to every gardener. The drug copes with the treatment and protection of crops from any bacterial diseases, regardless of the reasons for their occurrence.

However, there are disadvantages of Bordeaux liquid, which are best known before using in the garden.

• Destroys pesticides that are unstable in an alkaline environment.
• The quality of protection depends on the thoroughness of processing. Bordeaux liquid is a contact fungicide, treated areas are protected, missed ones are not.
• Copper tends to accumulate in the soil, an excess of copper negatively affects plants and the ecosystem in general.
• Difficulties in application lie in the clogging of the spray gun. An improperly prepared solution can cause burns to the leaves.
• The main drawback of copper is that it is poisonous to humans. Plants must be handled carefully, without falling on the fruit. Be sure to use protective equipment - a respirator and goggles for the eyes.

The use of Bordeaux liquid

Read the instructions for using Bordeaux liquid before you start working on the garden. Consider the peculiarities of using the solution in working with different types of crops.

• Traditionally, spraying the garden with Bordeaux liquid is carried out twice a year. The spring processing of the garden must be carried out before the buds swell on the trees, the autumn processing of the garden - at the end of all work, at the end of November.
• Spring and autumn spraying is carried out with a 3% solution of Bordeaux mixture. If it is necessary to repeat the treatment in the middle of the season, use a 1% solution of Bordeaux mixture.

• Stone fruits are the exception. They are susceptible to preparations containing copper, so it is undesirable to treat them more than twice a year.
• Carry out the processing of the garden in dry, calm and cool weather. A rainy day can cause burns on the leaves.
• Cover tree trunks with liquid abundantly so that the solution, flowing down, flows into all the cracks, where harmful organisms usually gather.

Proper use of Bordeaux liquid is safe and effective. Do not neglect the instructions given in the article to protect the plants from the negative effects of the solution.

Bordeaux liquid It is used to protect fruit and berry crops from fungal and a number of other diseases. The drug belongs to the category of contact fungicides and is a water-suspension concentrate (WSC) of tribasic copper sulfate. Finished Bordeaux liquid in a bottle it is distinguished by its effective action and ease of use, due to which it has been widely used in personal subsidiary plots and summer cottages.

Application features

The drug must be dissolved in water according to the attached instructions: first in a small amount, and then add it to the required volume. The prepared liquid cannot be stored and must be used immediately.

First processing Bordeaux liquid carried out during the green cone phase, when leaves begin to emerge from the buds. During this period, horticultural crops are especially susceptible to fungal diseases. Early spring spraying begins to act after two hours and protects trees and shrubs for the next 50 days.

The treatment can be repeated during the growing season, after flowering, and then weekly. It should be borne in mind that a certain time must pass from the time of the last spraying to harvest. It is called the waiting period and is indicated in the instructions.

Bordeaux liquid used to protect the garden from septoria, scab, moniliosis, klesterosporiosis, columnar rust and other common diseases. Subject to the recommended standards, it is not phytotoxic, that is, it does not inhibit the growth and vital activity of horticultural crops.

To buy Bordeaux liquid just contact our partners. The site has a list of stores that sell drugs from the company "August" in the section.

- This is a drug that is used against pests and many fungal diseases of plants.

This tool can be purchased at any specialty store and is considered an effective fungicide. Just like in ancient times, this tool has a wide spectrum of action.

This drug helps to eliminate the following harmful plant diseases:

1. Signs of scab.
2. Manifestations of clusterospirosis, coccomycosis (usually after 4 treatments).
3. The appearance of anthracnose on gooseberries (up to three sprays).
4. The manifestation of spotting on the leaves of raspberries and strawberries.
   (usually disappears after two sprays).

The mixture is treated with the following crops:

1. Winter crops - from snow mold and root rot.
2. Potatoes, tomatoes - from late blight.
3. Melons, watermelons, cucumbers - from anthracnose.
4. Beets.
5. Onion - from rot.
6. Apple and pear crops - fruit rot, leaf spot, rust.
7. Cherry plum, plum, cherry - coccomycosis, clasterosporiasis and others.
8. For flowers and shrubs - fungal infections.
9. Grapes and currants - mildew and black rot.
10. Peach - from curly leaves.

In addition, in order for the mixture to really help and cure plants from serious diseases, it is advisable to follow the recommendations for its use:

1. Processing of plants should be done in early spring, just before flowering. Be sure to pay attention to the kidneys, they should not be loose.
2. Spraying should not be done at a high level of atmospheric humidity and at high temperature conditions. Otherwise, it may cause leaf burns.
3. It is not advisable to add carbofoss and organophosphorus compounds to the Bordeaux mixture.
4. If you are a little late with spraying, then it can be done immediately after the opening of the kidneys. But for spraying, you need to use a 1% solution, a more saturated mixture can cause burning of the leaves. These treatments are the most effective for the control and prevention of grape diseases.
5. During irrigation, make sure that the liquid completely covers the plants. This is the only way to get visible results.
6. Pay attention to the fact that even 1 solution can cause burning to especially tender varieties of grapes, roses, berry bushes and trees. The most sensitive plants to this remedy are apricot and cherry. As a result of processing, their fruits are deformed and cracked. For them, it is best to use replacements-HOM, Blue Bordeaux, Kuproksat.
7. You can also do an eradicating spray with 3% liquid. Usually the foliage after this treatment becomes blue in color. The effect usually lasts for about a month.

1. Dosage

The preparation of the Bordeaux mixture is a very responsible process, which must be approached with particular care. In this case, it is important to observe the dosage of the remedy. Otherwise, the wrong dose of the product can lead to the death of all plants.

So, for 10 liters of liquid, the following dosages must be observed:

1. 0.5-0.75% solution: 100 grams of copper sulfate, 75 grams of lime.
2. 1% solution: 100 grams of copper sulfate and 150 grams of lime.
3. 3% solution: 300 grams of copper sulfate and 450 grams of lime.

2. Flow calculation

It is advisable to observe the amount of solution during the processing of various plants and trees.

It is different for every plant.

1. For young trees, whose age is not more than 6 years, you will need 2 liters per tree.
2. When processing fruit-bearing plants, 10 liters will be required.
3. For shrub plants - 1.5 liters per shrub.
4. With preventive measures for grapes, raspberries and strawberries - one and a half liters of solution is enough for 10 square meters.
5. To process tomatoes and cucumbers - 2 liters of solution will be required per 10 square meters.
6. When processing melons, watermelons, onions, beets - 1 liter of solution is needed per 10 square meters.

The composition of the Bordeaux mixture

Bordeaux mixture consists of lime mixture and copper sulphate powder. The main active ingredient of this product is copper compounds that are slightly soluble in liquid, due to which long-term protection is provided.

But lime and vitriol must be mixed right before use. They are usually packaged in individual bags.

Also, do not forget that depending on the concentration of copper and vitriol, the chemical composition of the solution itself changes. If there is a lack of lime, this can lead to plant burns.

That is why after the alkaline reaction is checked, it should be added additionally.

Preparation of Bordeaux mixture

It should be borne in mind that the preparation of the Bordeaux mixture is quite complicated, so everything must be done correctly.

Otherwise, the solution may turn out to be too concentrated, and when spraying delicate plants, it will harm them. Or, on the contrary, a weak concentration, then it will not bring the expected effect.

So, consider the step-by-step preparation of a 1% solution per 10 liters:

1. To dilute the solution, you need to use any non-metallic container.
2. In warm water, you need to dilute 10 grams of copper sulfate. Everything is thoroughly mixed.
3. Next, you need to add cold water to this mixture so that the total volume is 5 liters.
4. In a separate bowl, you need to dilute 120-130 grams of slaked lime in 1 liter of water. Everything is thoroughly mixed, as a result, a mixture should be obtained in consistency, reminiscent of sour cream.
5. Then water must be added to the lime mass so that the volume is 5. Mixes well.
6. We filter the lime mortar through gauze material. This is necessary so that the sprayer is not clogged with lime particles.
7. In no case do not confuse what and where to pour! Stirring with a wooden stick or spatula, carefully pour the blue vitriol into the lime mixture.
8. Everything mixes well. It is advisable to simultaneously stir the lime and pour in copper sulfate.

The preparation of a 3% solution is the same, only it differs in concentration. This solution will require 300 grams of copper sulfate and 400 grams of slaked lime.

Also, after preparation, it is necessary to check the acid reaction of the solution. To do this, any metal wire or nail should be lowered into it. If, after lowering, the metal becomes red, then a little more lime should be added to the solution.

Also remember what not to do:

1. Do not pour lime mixture into a solution of copper sulphate. This will greatly reduce the quality of the solution.
2. No need to mix warm and cold ingredients.
3. Combine dry ingredients.
4. Pour into the prepared water solution.
5. Add dry copper sulphate to diluted lime.

Precautionary measures

Be sure to follow the safety rules and precautions when using this solution:

1. Be sure to wear gloves, a respirator, a hat and protective clothing during preparation and spraying.
2. Never drink, smoke or eat food between sprays.
3. Do not spray the mixture in close proximity to fruits, vegetables and berries that will be harvested within 2-3 weeks.
4. Be sure to rinse fruits, vegetables, fruits, berries before use.
5. It is not necessary to do processing during flowering of plants.
6. Processing should not be carried out in strong winds, rains and heavy dews.
7. In no case do not mix it with other drugs and fungicides, this will only reduce the effectiveness of the product.
8. It is not desirable to add a soapy solution to the mixture, which improves adhesion. Perhaps the adhesion will be good, only the solution will be ineffective.
9. The last spraying should be done 2 weeks before harvest.
