Colloidal sulfur: instructions for use for grapes, currants and other plants

The use of colloidal sulfur is often practiced in gardening when plants are damaged by diseases and pests. The drug is highly effective and remains quite safe.

What is the difference between colloidal sulfur and regular sulfur?

Colloidal sulfur is a type of regular sulfur, but contains certain impurities that enhance the beneficial effect of the drug. It looks like a yellow powdery substance with a grayish tint. May also be sold as water-soluble granules.

Composition of colloidal sulfur

The main part of the drug is ordinary sulfur. It accounts for up to 95% of the total volume. In addition, colloidal sulfur includes surfactants, sodium thiosulfate, lignosulfonic acids and monopotassium phosphate.

In its normal state, the drug remains passive, but when it gets on the surface of plants, it begins to interact with protein structures and releases fumes that are toxic to fungi and pests. Colloidal sulfur does not accumulate in the tissues of agricultural crops and in the soil.

The effectiveness of colloidal sulfur increases with increasing air temperature

The drug is produced in small sachets of 20 g and in bags of 50 kg. When diluted with water, the substance forms a suspension and is poorly soluble in alcohol.

What is colloidal sulfur used for?

Sulfur is widely used in gardening for the prevention and elimination of fungi and insect pests. In particular, the product benefits:

• for powdery mildew and blackleg;
• with grape oidium;
• with anthracnose and ascochyta;
• for scab;
• with gray rot;
• when damaged by ticks and other pests.

The drug not only protects plants, but also serves as a useful fertilizer for them. Sulfur is often added to the soil in the spring as a fertilizer.

What plants is colloidal sulfur used for?

How to dilute colloidal sulfur in water for processing

The use of colloidal sulfur in the garden must take into account the characteristics of a particular crop. But there is also a general algorithm for preparing a solution for therapeutic and preventive treatments. It looks like this:

1. The required amount of sulfur powder is poured into a clean container.
2. Dilute the preparation with warm water and stir thoroughly.
3. Add another 1 liter of liquid.
4. Stir the sulfur a second time.
5. The resulting homogeneous mixture is diluted with 8 liters of clean water.

It is recommended to prepare sulfur immediately before processing crops. Upon completion of spraying, the remaining product is disposed of. Treatments are carried out at a temperature of 18-27 °C.During the season, up to five sprayings are allowed.

Plants can be dusted with dry sulfur, but first it is mixed in equal proportions with talc or ash
