Copper sulfate for grapes: how to breed for processing and spraying

Despite the efforts of breeders, most of the products grown on the site need protection from harmful bacteria and insects. Since ancient times, it has been believed that copper sulfate is one of the most effective means to maintain plant immunity at the proper level. Let's see how copper sulfate is useful for processing grapes, and how it is done.

Types of vitriol

Vitriols - sulfate s alts of metals, which include water of crystallization. To date, the following types of vitriol are known, some of which are formed naturally, and some only artificially:

copper;
cob alt;
iron;
manganese;
zinc (white);
nickel.

Composition and active ingredient

Copper sulfate is a powdered substance with a light blue or blue color. It dissolves well in liquids, because there are 5 molecules of water per 1 molecule of copper sulfate. The formula of the substance is as follows - СuSO45H2O. The substance is not safe for the human body and has a category 3.

Pay attention! Vitriol enters the human body through the skin and mucous membranes. Beware of direct contact with him, because this is fraught with consequences. Do not forget about the safety rules when working with it.

Advantages and disadvantages of the drug

The substance is used in horticulture due to the following qualities:

The effect after processing the culture remains for a long time.
Low cost.
Wide scope.
Used sparingly and purchased stock will last a long time.
After applying the vitriol solution to the product, it is possible to eat it earlier than with other preparations.

Flaws:

determining the required dosage by eye is difficult, and when drawing up the solution, clear rules must be followed;
if the liquid is too saturated with vitriol, instead of protecting against pests, you will burn the bush.

Destination

The range of applications in horticulture is wide. So, vitriol is used when:

fertilizing the bush;
processing plants from fungal infections;
processing grape cuttings to strengthen immunity;
disinfection of damaged areas of the bush.

Each method requires an individual approach and compliance with the rules specified in the instructions for use.

Feeding

Beginner gardeners are wondering if this substance can be used as a top dressing? Yes it is possible. Vitriol, as a fertilizer, is effective in the case of grapes growing on peat bogs and sandy soils. On chernozem, the beneficial effect of fertilizer comes to naught.

The substance feeds the developing plant with copper, helping to fight harmful bacteria and stimulating photosynthesis. Feeding dosage: 4 grams of the substance is added to 10 liters of liquid.

Treatment for fungal diseases

Helps fight the following diseases:

powdery mildew;
white and brown spotting;
scab;
effective against fungal infections.

Ingredients: water, blue vitriol, skim milk or laundry soap. Milk or soap is required to increase the effect of drugs. If you add 100 grams of stickiness enhancer to a bucket of water, the protective film will last longer on the plant and will not be washed away by rain.

Processing cuttings

Seedlings soaked in a 2% solution of copper sulphate have increased resistance to harmful bacteria. This procedure is carried out before planting and increases the chances of the sprout to form into a powerful, beautiful bush that gives a stable harvest.

Wound disinfection

To create a disinfectant solution for treating plant wounds, you need to prepare:

10 liters of water;
100 grams of substance.

Having treated the wounds of a bush or tree with the received medicine, you can not be afraid of their inflammation and death of the plant.

How to use in vineyard

Preparing a solution for plantation treatment has a lot of nuances, and the preparation technology depends on the method of applying the liquid. For the correct preparation of the medicine, follow the following preparation rules.

Preparing the solution

Gardeners who do not know how to prepare a solution of copper sulfate should adhere to the following rules:

dissolve the substance in warm water;
when preparing the mixture, do not forget about safety rules. Wear rubber gloves and other personal protective equipment available;
don't mix the solution in a container made of metal.

Dosage of copper sulfate for various treatments

Instructions for those who do not know how to dilute the spray agent:

1% solution is being prepared for spraying. Accordingly, no more than 100 grams of powder is diluted per 1 bucket of warm water;
stir the water until the powder is completely dissolved;
pour the resulting mixture into the sprayer.

Important! Do not mix copper sulfate solution with other chemicals. The effect of such a mixture is difficult to predict, and instead of a positive effect, you will destroy the plant, and possibly your he alth.

Steps and procedure for processing grapes

Processing steps:

shake the container with the drug;
carefully, following the safety rules, spray the substance;
we process trees or other plants on the territory with the remaining solution.

In order not to burn the plant, check the correct dosage by treating one leaf on the bush. If after a while no traces of burns are visible, the solution is made correctly.

Timing of the procedure

Grape processing time:

spring;
autumn;
summer.

Autumn processing is considered the main, spring - additional, and the treatment of the bush in the summer goes as an auxiliary procedure if the plant needs it.

Sprinkling on dormant vines in spring

Spring processing is carried out as follows:

a few days before processing, the vine is freed from the material that shelters it from the winter cold;
make a solution;
apply the substance in a uniform, thin layer over the entire surface of the vine.

Important! Processing is carried out before bud break, while the ambient temperature should not be lower than 5 ^o.

Green leaf processing in summer

In summer, treatment is carried out as a last resort, with a solution whose concentration does not exceed 0.5%. It is advisable to carry it out at the first signs of the disease.

Autumn

Held at the end of the grape harvest, when the leaves have already fallen from the bush. The best period is the beginning or end of November. It all depends on where you live. Tie the vine around the trellis before starting.

Errors encountered while processing tool

The main mistake, the commission of which will cost you the death of the bush, and, accordingly, the crop, is the wrong dosage. The substance in high concentration will burn the grapes and harm your he alth. Another common mistake is processing frequency. It is not worth treating the bush every month, especially disease-resistant varieties.

How to make your own liquid

To make a liquid with your own hands, use the instructions on the packaging of the substance or the cooking technology described above. The basic dosage is considered to be 1% solution. Using it, you will not harm the vine bush or other cultivated crop.

Safety when working with chemicals

When preparing the solution and processing plants with it, remember the main thing - safety. The plant can be grown again, and he alth is almost impossible to restore.

When working with copper sulphate, follow these rules:

don't forget to wear rubber gloves. This will protect your skin from unwanted contact with chemicals;
a respirator will also not be an extra detail in your equipment;
it is advisable to prepare the solution outdoors or in a well-ventilated area;
at the end of preventive procedures, thoroughly wash equipment and tools.
