Colloidal sulfur for grapes: instructions for use for processing

Many growers grow grapes for fresh drinks and fruit dishes. When growing grape bushes, they are often faced with the fact that they suffer from some fungal pathologies. To protect the seedlings, you will have to treat them with colloidal sulfur for grapes. However, before that, you need to familiarize yourself with the features of the use of this mixture.

Assignment of colloidal sulfur

Before you start processing grape seedlings, you will have to familiarize yourself with the description and purpose of the chemical. Gardeners use it to treat plants for diseases that are caused by fungi.Also, mixtures prepared from colloidal sulfur are used to prevent pest attacks. Regular application of the sulfur mixture helps to eliminate fungi in vineyards and prevent their further development.

Experienced growers identify several purposes for processing bushes with such a substance:

Prevention and elimination of diseases such as anthracosis, oidium, powdery mildew.
Protection of planted seedlings from plant mite attacks and prevention of pest development.

The effectiveness of the fungicide is based on the vapors that the sulfur solution emits. After spraying, the treated bushes begin to wrap themselves in pairs. They are absolutely safe for plants, as they do not penetrate into their plant tissues. The components of sulfur matter get inside pests and fungi, after which they are gradually destroyed at the cellular level.

Method of administration and dosage

It is recommended to figure out in advance how to treat grape bushes with a fungicide. This will help instructions for the use of the drug, which will describe all the nuances of spraying.

First you have to prepare a working solution, which will be used in processing. To prepare a spray liquid, 50-60 grams of sulfur powder are gradually added to ten liters of water. To make the solution more concentrated, the dosage is increased to 70-80 grams. The powder must be diluted in water so that the mixture becomes homogeneous.

When creating a working fluid, the mixture is thoroughly mixed so that there are no lumps and undissolved sulfur powder in it. Gardeners with many years of experience in the use of fungicides are advised to prepare a solution from heated water, as the powder dissolves better in it.

Sprinkling of grapes is carried out on the same day that the liquid was prepared.

At the same time, it is better to process grapes in calm weather so that the fungicide does not get on nearby plants. The amount of spraying the vineyard depends on how affected the bushes are. On average, they are processed at least six times a season. In case of serious damage to plants by fungal diseases, the number of treatments is increased up to ten times per season.

Precautions

Many believe that colloidal sulfur is only beneficial and absolutely safe for humans, but this is not so. If you carelessly use a fungicide, you can harm your he alth. There have been cases when, due to the improper use of sulfuric solution, poisoning and allergic reactions appeared in people.

To avoid such problems, you will have to familiarize yourself with the basic precautions for using a fungicide mixture.

Before you start spraying grapes, you need to take care of personal protective equipment, which is necessary to prevent liquid from entering the skin surface. The best choice would be a special overall made of durable rubber. A respirator with goggles is suitable for protecting the eyes and respiratory organs. You also need to make sure that there are no animals or people nearby when spraying plants.

When processing grape seedlings with sulfur, you can not drink, eat or smoke. When spraying is over, the mouth, nose and hands are thoroughly washed. Laundry soap is used to wash particles of the fungicidal liquid that could get on the skin.

Pros and cons

Like most fungicides, colloidal sulfur has its advantages and disadvantages. Benefits include:

Duration of action. Sulfur is classified as such substances, the effective effect of which is quite intense and long-lasting. Therefore, one spraying is enough for 2-3 weeks.
Good compatibility with other drugs. Experienced gardeners often use colloidal sulfur along with other insecticides and fungicides.
Safety. Vapors that are released during the processing of grapes are not able to penetrate the leaves or berries.
Release form. Since the drug is sold as a loose powder, it is quite easy to control the dose.
Versatility. A mixture made from sulfur is versatile, as it is used for treatment and prevention.

Disadvantages of sulfur solution are much less than advantages. Among the main disadvantages are the insecurity of sulfur for humans, as well as the difficulty of spraying high grape bushes.

Processing times

Before you use colloidal sulfur, you need to understand the timing of its use.

The following processing times are recommended:

The first spraying can be carried out in early March, when there are no leaves on the bushes yet. In this case, non-concentrated mixtures are used.
Experienced growers recommend re-processing when the first open buds appear on the branches. Most often they open in mid-April.
The third time the grapes are sprayed in the first weeks of May, when the bushes are covered with young leaves.
The fourth treatment is best done in July or June, before pollination.

Storage conditions

Cooked sulfuric liquid can not be stored for a long time, as it quickly deteriorates.Therefore, you will have to use it within 5-7 hours after preparation. However, colloidal sulfur in powder form can be stored at home for a long time. For this, rooms with moderate humidity and room temperature are suitable. With high humidity, the powder will begin to clump and deteriorate.

For the storage of fungicides, places are selected that are reliably protected from children. It is better to put them in boxes that are locked with a key. Under optimal conditions, colloidal sulfur is stored for 1-2 years.

Conclusion

Grapes, like other plants, are often attacked by pests and suffer from dangerous pathologies. To cure it and protect it from insects, you can use colloidal sulfur. However, before that, you will have to familiarize yourself with the description of this tool and the nuances of its use to protect grapes.
