Therefore, it is important to carry out preventive spraying annually and treat the berry culture in a timely manner with drugs that can protect them and destroy the pathogen. One of the most popular products is Topaz.

It is actively used to protect and treat gooseberries, grapes, and currants. On the market, it is presented in 2 ml ampoules, 3 ml sachets, plastic liter bottles.

Did you know? Together with the American gooseberry, Christopher Columbus brought to Europe from South America a “ new disease ” - American powdery mildew, which later spread to Russia and led to the destruction of most gooseberry plantings with large fruits.

Processing time: spring, autumn

In accordance with the instructions "Topaz" can be used from early spring to late autumn. Between treatments, a time period of 2 weeks should be maintained.

It is necessary to spray the plants with the preparation on the day when the wind force is not more than 5 km / h, in the morning or in the evening. The action of the drug begins 6 hours after treatment and lasts from 7-8 to 14-17 days, depending on the intensity of the development of the disease. The active substance is absorbed by the plant in the first 180 minutes.

Spraying the working solution should be uniform

To prepare a mixture for spraying, you will need dishes in which the drug must be diluted with water, as well as an object (stake, rail, etc.) to stir, a special garden sprayer (sprayer).

Treatment

In order not to cause additional harm to the plant, when using the drug, it is necessary to strictly adhere to the instructions and follow the correct dates.

For preventive purposes

In order to prevent powdery mildew, gooseberries are sprayed in early April, before the onset of kidney swelling. In 10 l of water, one ampoule of the drug is diluted with a volume of 2 ml. First, this amount is poured into a small container with water, and then the volume is adjusted to 10 liters. The finished substance is poured into the spray tank. The prepared solution of the above volume is used to treat an area of ​​100 m².

Important! The shelf life of the Topaz ready-made solution is 8 hours.

The second spraying is carried out after flowering, after 2-3 days, when the first ovary is formed . If, for any reason, the re-processing period has been missed, then it is possible to spray already on the green berries and 1.5 months before they are fully ripened.

The solution must be prepared immediately before use.

In the presence of a disease

It is important to detect the disease in time in order to begin treatment at the initial stage of its development. To get rid of powdery mildew (sferoteka), the drug is bred in the same proportion as for prevention. It is used repeatedly, withstanding breaks of 10-14 days, until the symptoms disappear completely. The maximum number of sprayings is 4. The flow rate of the working fluid is 1-1.5 liters per bush.

For the treatment of rust, it is necessary to increase the dosage, diluting 4 ml in 10 liters of water.

Errors in the treatment of gooseberries with Topaz fungicide and their consequences

When processing berry bushes, the following errors are most often made:

1. Weather conditions are not taken into account, as a result of which the drug is washed off by precipitation or quickly evaporates.
2. A stale solution is used, the effectiveness of which is significantly reduced.
3. Recommended treatment times are not respected. As a result, the tool does not work properly.
4. The proportions indicated in the instructions are violated. Improperly prepared working solution is ineffective or harmful to the plant.
5. The drug is used at a later date - later than 20 days before harvest. Thus, berries that pose a threat to human health will be obtained.

Important! Since the active substance is able to accumulate in the soil, it is not recommended to use the same drug for more than three consecutive years in one place.

So, “Topaz” is a systemic fungicide that effectively fights gooseberry diseases caused by fungi. Correct and timely use of the drug allows you to reliably protect the plant from the sphere library and rust.
