In order for the vineyards not to get sick and bear fruit well, they need constant care. But even in this case, the plant is often exposed to various diseases. To combat them, there is a universal remedy called colloidal sulfur. It is used both for the treatment of diseases and for preventive measures.
Description and purpose
Colloidal sulfur is a drug that has a positive effect on the vine, prone to all sorts of diseases.
But first of all, the remedy can resist fungal diseases.
With the help of colloidal sulfur, you can fight various ailments.
Oidium or powdery mildew. The main symptom of the disease is the formation of white plaque on the foliage. At the same time, the inflorescences fall off without even having time to bloom, and the clusters are very small. Powdery mildew is caused by a fungal bacterium.
Downy mildew differs from the present in symptoms of manifestation. In this case, the lower parts of the leaves are covered with a white bloom. Berries are covered with it, and cracks appear on their peel. The fruits begin to rot or dry out. Dark spots can be seen on a vine that is susceptible to this infection.
Anthracnose is another disease, the first sign of which is the appearance of dark spots on the vine. As the disease progresses, holes form in place of the spots.
Gray rot. Symptoms of this disease can be seen visually. A plaque appears on the clusters, outwardly resembling mold.
Colloidal sulfur for grapes belongs to the category of non-toxic fungicides. A characteristic feature is the absence of penetration of the substance into the tissues of the plant. But despite the absence of toxicity, it is not recommended to use the solution too often (no more than 5 times per season).
Instructions for use
In order to prepare a solution, it is necessary to mix 80 g of the substance with 10 liters of water. If the remedy is not used to treat diseases, but only to prevent them, then the concentration of colloidal sulfur in water should be slightly reduced. Breeding is best in a plastic bucket.
Before proceeding with the processing of plants, it is necessary to determine the period. The most favorable option is processing in July (before flowering). But it is also not forbidden to carry out processing in August (usually ovaries begin to form during this period).
Final spraying should be carried out a few days before harvest. If processed according to this scheme, then the maximum effect can be obtained from the treatment.
For prevention, grapes should be sprayed in early spring, even before bud break. Preventive measures are very important because they prevent the occurrence and further development of diseases.
For the treatment of any disease, the dosage remains unchanged: 80 g per 10 liters of water. This volume is enough to process approximately 60 square meters. m. For prevention, you can dilute the solution a little weaker. The waiting period for the effect of the therapy is several days.
Vineyards can be processed at almost any time of the day. But it is best to do this in the afternoon, when the activity of the sun is significantly reduced. You should also be aware of the weather. It is very important that it does not rain in the near future after treatment. Otherwise, the effect of the treatment will be scanty.
If the air temperature drops below +16 degrees, then it is almost pointless to carry out processing.
Fact is that the destruction of fungi actively occurs when the substance passes into a vapor state. And for this, the air temperature must be above the indicated indicator.
Safety measures
During the processing of vineyards, it is recommended to take precautions. Of course, colloidal sulfur does not belong to substances toxic to humans, but protection will not be superfluous.
Processing is best done in calm weather so that drops do not fall on the person who sprays. As personal protective equipment, it is recommended to use a mask or respirator, goggles and a protective suit.
If the product still gets on the skin or mucous membranes, it is urgent to rinse this area under running water.
If necessary, seek medical attention.
After treatment with a chemical (meaning the final session), the berries must be washed before eating.
Storage nuances
Since colloidal sulfur belongs to the category of chemicals, certain requirements are imposed on its storage. The main condition is to store in a place inaccessible to children and pets. For storage, choose a cool and dark place where direct sunlight does not penetrate.
It is strictly forbidden to store this drug in close proximity to food, as well as medicines. In addition, it is better to store colloidal sulfur in its original packaging and not pour it into any jars, boxes or bags.
Sulfur belongs to the category of flammable substances, so it must be kept away from heaters and open sources of fire.
If the drug has expired, then it must be disposed of without opening the package. Using such a tool is unsafe and ineffective.
The principle of using colloidal sulfur differs little from those applied to fungicides of this purpose. The main thing is to follow the instructions for use, and not to neglect the precautionary measures. And also do not over-treat, since even the safest chemical can harm the plant.
