Step-by-Step Guide to Apply Bordeaux Mix

Completely at the end of the XIX century, a farmer from the city of Bordeaux (France) invented a mixture for processing its vineyards. For this, he mixed lime and solutions. The effectiveness of this drug shocked all Bordeaux winegartes. It is used in the fight against fungal and bacterial diseases.

Benefits of the mixture

1. Long is held on the treated plants. It does not lose the quality of the effectiveness of this pesticide.
2. Bordeaux mixture is a chemical preparation that has high fungicidal activity. This means that he is very effectively fighting fungi and their disputes.
3. Processed plants have a good clarity of spray quality.
4. Simplicity of cooking this mixture and its small cost compared to other similar products are additional advantages for buyers.
5. With all its effectiveness, this fluid is very gentle to plants.
6. Processed by burgundy liquid 3 hours before the rain of plants have time to get the necessary protection. This mixture in this case has good rain-resistant.

Disadvantages of the drug

1. Used immediately after cooking. Store no more than a day.
2. When preparing the mixture, you have to use 2 tanks. Lime quit in one container. In another dissolve copper vigor.
3. It is impossible to use metal products. Use clay, wooden and glass containers.
4. If the mixture is incorrect, without compliance with the cooking technology, then such a solution can harm the processed plants. In this case, they will receive strong burns when spraying, or will not bring a positive result.

Structure

Boroscopic liquid is obtained by mixing two copper and lime solutions

These are separate copper pivot powders and lime in a dry state.

This drug is a liquid compound of solutions of these substances.

Depending on the treated types of vegetation, the time of use is prepared a solution of a certain concentration. In some cases, it is necessary to prepare a liquid of 3%, in other situations it will require a preparation of 1%.

Preparation of solution

1% solution

10 liters of such a chemical need:

1. 100 g of chopped copper vitriol pour into a small amount of warm water (no more than 50 ° C).
2. Bring the resulting volume to 9 liters.
3. In the second container, it is necessary to dissolve 100 g of lime water temperature. Liquids take a small amount. This water is topped with small portions. It is necessary to obtain a sour cream fluid. Take up so much water to get 1 l of such a solution.
4. The resulting limetric "milk" is filtered.
5. The copper sulfate solution is gradually poured into a limestically stirring. The flowing jet should be very thin. The operation must be carried out when both room temperature fluids.
6. The color of the cooked liquid indicates the correct preparation.

   If it has a blue color - this indicates the correct preparation.

   Additionally, it is necessary to determine its reaction: acid or weakly alkaline. Better if it is the second option. The drug that has an acidic reaction is very phytotoxic (suppresses the growth and development of plants). Larous very well keeps on the treated plant surface.

7. A strong drug is short-term in its action.
8. The easiest option to determine the reaction of the liquid is to lower the clean new nail or metal wire into it. If after 1-1.5 minutes, metal products are coated with a reddish chain - an acidic medium. Fix this condition to a weakly alkaline reaction can be adding lime solution into it.
9. The mixture is filtered through a very fine kitchen sieve or a loose fabric, immediately before spraying.

3% solution

The whole technological process is the same as previously considered. The difference is that in this case, 300 grams are used. Jumping and 300 gr. Lime. Each of these powders gradually dissolve in 5 liters of water (vitriol in warm, lime at room temperatures). All technology is similar to previous instructions.

Application

1% composition use as a repeated spray During the flowering period and the appearance of small barriers on fruit trees. The first time the processing is carried out stronger, 3% composition. Applied In the fight against the pair, spotted leaves, P. fillostose (bright spot, fungal disease), monilize (prolific rot, fungal disease). The same solution applies when protected from false torment on grapes I. from phytoftrophiz on vegetables.

3% mixture used in spring and autumn periods For processing garden, fruit and berry plants. In the fall, they apply after falling leaves from the trees of leaves. In the spring period, it is necessary to spray with liquid before the kidneys dissolve.

The principle of using this mixture is that it must be applied to healthy plants. Thus, she protects them from diseases. Such preventive work is more effective than treatment, especially launched forms of disease, allows plants to have a protective "screen" from pathogenic bacteria and fungal pests.

This chemical product is applied to cloudy dry weather. On a hot sunny day, the plants can get burns and from a proper prepared preparation of the recommended concentration. The time of the day of such work is early morning (without dew on plants) or in the evening. It is not recommended to carry out processing in the days of the expected precipitation.

The Dedovsky method of spraying with the help of domestic broom is ineffective, as the broom is unevenly sprayed plants. In addition, there is a large loss of the drug that flows over a broom to splashing. The work performed by the sprayer is effective.

Step-by-Step Guide to Apply Bordeaux Mix

1. Spraying spend early spring before and during the dissolution of the kidneys.
2. Prepare a 3% burglar mixture according to the instructions (see above).
3. Fill the manual or electric garden sprayer with a cooked liquid.
4. Take precautions, wear overalls, gloves and safety glasses.
5. Process:
   • fruit trees: non-pronomous seedlings: up to 2 liters on a tree. fruiting to 10 l;
   • , gooseberry - 1.5 liters per bush;
   • . Strawberry -1.5 per 10 sq. M. m;
   • grapes - 1.5 liters per 10 sq. M. m;
6. After the first processing, it is necessary to re-work through timebut already using 1% composition (according to the above instruction). At the same time, it should be noted that the flow rate for each type of plants (listed above) is the same as in the case of using 3% of the composition.
7. The number (multiplicity) of the use of such spraying.
   • for fruit trees 4-6 treatments for the season. The first processing is made during when buds acquire pink color;
   • currant and - 3;
   • raspberries and strawberries - 2;
   • grapes - 6;
   • In any soil - 4. 2 liters are required by 10 square meters. m;
   • cucumbers - 3. Using 2 l per 10 sq. M. m;
   • beets - 3. Consumption - 1 l by 10 square meters. m;
   • melon, - 3. Consumption - 1 l per 10 sq. M. m;

After the flowering of plants, this drug should not handle the plants, as it leads to premature falling off the wound and in the future leaves. And this all disrupts the natural natural cycle of plants.
