How to identify powdery mildew on gooseberries

At the first (conidial) stage of the disease, the shrub is affected by fungal spores, this manifests itself in the form of a white volatile plaque that can be easily removed. The mycelium is the main spread of the disease on gooseberries.

In spring, ascospores appear on the berries, which throw spores far beyond the bush, affecting other plants.

In summer, the disease enters the marsupial stage, the plaque spreads, it is brown with a hard crust. In autumn and winter, the fungus lives on the affected buds and shoots. He prefers to settle only on young shrub tissues - ovaries, new leaves, branches and fruits.

Symptoms of the disease can be seen 2-3 weeks after the culture is infected. If the spores hit the shrub in the fall, the first symptoms will appear on the young leaves. But most often the disease affects the culture in late May - early June.

In addition to plaque, this fungus can be identified by other signs:

• leaves are deformed, curled and fall off;
• ovaries crumble;
• fruits wrinkle and dark brown spots appear;
• shoots are bent;
• the growth and development of the shrub stops, and after a few years it dies.

Description of the disease and how to deal with it

You can understand the presence of powdery mildew on gooseberry berries if a loose, cobweb, loose white bloom has formed there. It will turn into brown spots over time.

3. Bush pruning is carried out regularly. It is not enough to cure the plant, it is necessary to remove the trimmed parts of the plant from the site and burn outside the territory.
4. Another measure is cleaning the area ahead of the winter season. The soil near the trunk space is carefully weeded, and a mulching layer is laid near the bush.
5. You cannot "overfeed" with nitrogen fertilizers. They only stimulate the active growth of greenery and reduce the immunity of the bush. Potash and phosphorus supplements will help to strengthen the resistance.Iodine also reduces susceptibility.
