Spraying grapes in the spring from diseases

With all the seemingly simple care of the grapes, this fruit shrub is very gentle and sensitively reacts to any changes in the weather or the appearance of organisms harmful to the plant. That is why it is so important to carry out the processing of grapes in early spring in order to protect it from diseases and pests.

What is it for?

It's no secret that the most appetizing and delicious grapes by nature are the most vulnerable. They can easily become infected with various fungi, from mildew to powdery mildew. And even good agricultural technology does not help here. Another danger is the frequent change of weather, from heavy rains to hot dry days, which greatly increases the risk of infection of grapes with fungal diseases.

Based on this, the spring processing of such an indispensable inhabitant of your garden will also provide reliable protection from harmful environmental factors, excellent growth and rich fruits.

Important! Pay attention to the appearance of this shrub after winter. If there are droplets of juice and bumps on the buds of grapes - This is a sure signal that it is time to urgently process the plant.
Processing in early spring should begin with a competent opening of the shrub after winter shelter. If the risk of frost in your area is low, then the grapes can be opened immediately from the moment when the air warms to a temperature above -2-0 ° С. If you live in the area where frosts often occur or their appearance is expected, make special ventilation holes for the spring period. The full opening of the plant is carried out only after germination of buds and the appearance of a green cone.

After this, it is safe to begin directly the processing of the fruit shrub itself.

Ways

For the destruction of all diseases and pests will be useful not only the treatment of the bush itself. If you process the soil quality, it will only increase the effect.

Spraying

Specialized chemicals will help you in the destruction of activated pests and plant protection from various types of damage throughout the season. Treating homemade grapes after winter by spraying the bushes prevents them from becoming infected with fungi and bacteria. If you are afraid of damaging strong chemicals to animals or plants, use special environmental products that are completely safe.

For reliable protection, it is necessary to process the stumps, sleeves, shrub vine and tree trunks.

Did you know? The content of nutrients, in addition to fat, grapes are closest to milk.

Tillage

A very important agrotechnical technique for growing this crop is the cultivation of the soil of the vineyard. The first spring soil treatment is carried out after cutting the bushes, but not later than the buds bloom. After the topsoil has dried, you can begin processing it. Dig the soil at a depth of 15 cm using a hoe. The second treatment in the spring comes at the end of May, when weeds sprout in large quantities and abundantly. Meteorological conditions, chemical properties of the soil, indicators of its humidity and weediness will help you in calculating the number of soil treatments.

In this case, be sure to provide the rhizome of the plant with plenty of oxygen. Mulching pristvolnyh circles using peat or compost will be an excellent addition to the first spring treatments.

Timing: when to process in spring?

Choosing dates when you want to spray grapes in spring, remember that processing can take several stages, each of them has its own characteristics and prerequisites.

Vines of grapes should be processed in the period after the opening of the bushes with a solution of iron sulphate in the ratio of 300-500 g per 10 liters of water. Use 200-300 g if swelling of the eyes is observed. This treatment does not guarantee the plant full protection against fungal diseases.

Its main purpose - the fight against harmful microorganisms that settle during the winter, and above all - with the mold that settled on the plant after the winter digging.

Important! Do not follow the generally accepted opinion that if you have already treated the shrub in the buds, the following spraying can be skipped.
The following processing is carried out in early May, when the 5th leaf begins to appear on a young bush. Hence its corresponding name - "on the fifth sheet." Also, the timing of this type of processing can be calculated by other signs: the first three rains, the average daily air temperature above 10 ° С and others. Before carrying out be sure to carry out the first wreck, removing all the excess shoots and their beginnings. The most beneficial for the plant will be preparations that show an active effect even in cold weather ("Horus" or "Strobe").

For better effect, you can add a special insecticide that helps to destroy ticks. For example, "Actellic" or "Fufanon". All subsequent processing should be carried out in the summer, immediately before flowering, when the clusters are already ripe.

This will increase the immunity of the shrub, as well as protect against the occurrence of fungal diseases and prevent premature drying of the foliage. To grow a good grape harvest, pay a lot of time and attention to it, watch for the slightest changes in the state of the plant.

Means for grapes

Many gardeners face difficulties choosing how to process grapes in the spring immediately after it is discovered. Some people prefer store supplies, while others adhere to popular methods, considering them more environmentally friendly and safer.

Did you know? Almost 80 thousand square kilometers on the planet Earth is planted with grapes. 71% of the crop is used for wine production, 27% is used as fresh fruit and 2% as dried fruit.
Before spraying, it is necessary to carry out the garter of the bushes, thus lifting them from the ground. This can help trellis or wire.

This will protect the plant from damage such a common and annoying disease like mildew, which is caused by the overmoistening of the vineyard after the thaw and rainy weather. Be sure to tie it only in dry weather.

Fungicides and insecticides

Fungicides are chemicals intended to fight against fungal diseases of plants, as well as for seed dressing, as a result of which they are released from the spores of parasitic fungi. At the same time, insecticides are quite effectively used in the destruction of harmful insects.

Learn how to transplant grapes, how to feed, how to graze, how to plant, how to cut and how to deal with pests of grapes.
All fungicides and insecticides are divided into 3 groups:

  1. Contact action.
  2. System action.
  3. System-contact action.
Contact drugs affect the pathogen only if the substance is in direct contact with activators of infection. They can not penetrate deeply, hitting the plant cells, and act only on its surface.

This type of drugs is characterized by a short waiting period, it very quickly and effectively destroys fungal spores. They can re-process the bush, since the parasites do not get used to it and each operation will be effective. At the same time, their action will be minimal with deep infection of cells; they are not resistant to precipitation, which gives them useful properties only for a short period of time.

Systemic preparations get into the tissue of grapes at high speed and provide the plant with almost complete protection. They have a deep healing and prophylactic effect on the whole bush; these substances also protect it in the local processing of leaves.

Racks to rain, thus providing lasting protection. Systemic medications have a long waiting time. Their use is not recommended more than two times per season.

System-contact drugs, respectively, have a complex effect on the grapes, combining the properties of the two species described above. Consider them individually, carefully read the information on their proper use. Many gardeners prefer to sprinkle grapes in the spring from diseases of copper sulfate. It effectively acts at any time of the year, is the most affordable means. If the plant is sick, and its leaves fall off, which indicates a lack of iron, be sure to carry out the processing of this drug.

In this way, you not only reliably protect the grapes from various diseases and parasites, but also spend an excellent fertilizer of the soil.

Folk methods

Popular methods are widespread due to their safety with respect to people and animals, which cannot be said about chemical means. However, if the plant is still not able to protect in time and it has become infected, they become relatively ineffective. The most widespread: onion peel, yeast, honey, leaves of celandine, aloe, soda, soap and other means.

The most affordable, popular and common folk remedy among winegrowers is an infusion made from onion peel. It is used in the treatment of plants before flowering and after it.

It should be cooked in this way: half a bucket of onion peel cover with water, boil for 20 minutes, then leave for 24 hours. Next, add water to a volume of 10 liters, add 1 tablespoon of honey, strain and ready infusion can spraying the vineyard.

Another common tool for gardeners is the infusion of hay rot. It helps in protecting the plant from oidium. For cooking, fill the bucket with dry hay, cover with water and leave for 7-10 days, then strain and boldly treat the shrub. When deciding how to sprinkle homemade grapes in the spring, to protect them from all diseases and dangers, be guided by the state of your plant. If it is generally healthy, but there are small signs of infection, use better folk remedies.

In this way you protect and shrub, and their health. If the incidence of a disease or parasite is large, then undoubtedly use chemicals that will quickly and effectively cope with the problems that have arisen.
