Garden strawberries, better known as strawberries, are a favorite berry for millions of people. This is no accident: it combines a wonderfully pleasant taste, tenderness of texture, pure natural beauty and the benefits of live vitamins. That is why the berry is grown in almost every garden and summer cottage in every corner of our country. And it is very disappointing when the harvest disappears or does not happen at all, which happens due to the attack of some harmful microorganism. Therefore, it is important to recognize strawberry diseases and treat them in accordance with the correct diagnosis. As you know, choosing the right path is half the battle.

Fusariosis (Fusariosis wilt)
A malignant disease that affects the entire bush, from the root system to leaves and stems,which change color, wither and eventually dry out. The source of the problem is a parasitic fungus, which feels especially good in hot weather. It remains in the soil for several years and is transmitted to strawberries from beds that were previously occupied by infected vegetable crops.
Treatment
Prevention is the main way to protect seedlings: they must be he althy, adapted and planted in areas free from parasites. If the symptoms have already appeared, then you will have to use chemistry: Fundazol or Benorat.
Black Rot
Disease affects berries. From the name it is clear what the infected fruit looks like: it is covered with black spots, which are clusters of fungal mycelium. High temperature and relative humidity play into the hands of the pathogen.
Treatment
Prevention of the problem is to grow a crop under cover, in high or vertical beds, where a damp microclimate will not be created. With the development of the disease - spraying with Ordan (autumn) and Euparen or Switch (spring).
Light blight
Another name is leather rot. It affects berries at any stage of the growth point formation. Contributes to the development of the pathogen drip moisture: rain, dew. The berries become bitter, unfit for food, and then mummified.
Treatment
Before flowering, seedlings are sprayed with Metaxil, Ridomil, Quadris. You can prevent the problem by planting he althy bushes,observing crop rotation and using annual garden strawberries.
Grey Rot
In warm and humid weather, it deprives the gardener of 30-60% of the crop. On any part of the bush or on the berries, soft brown spots are formed, covered with gray fluff - a coating of fungal spores.
Treatment
During spring growth, they are sprayed with Switch, Derozal, Topsin M or Euparen preparations. In rainy summer, the operation is repeated after flowering.
Powdery mildew
On the green part of the bush, areas of a delicate, almost imperceptible white coating appear, turning into a rich, powdery color.
Treatment
At the initial stages, "Trichoderma" is effective, with a strong lesion - broad-spectrum fungicides.
Strawberry diseases and their treatment is not an easy topic. It is often difficult to distinguish the work of one parasitic fungus from another. However, we can confidently say which diseases are caused by a fungus, which ones are caused by a bacterium or a virus. And based on this, choose adequate therapy with an appropriate broad-spectrum drug.
You can avoid the invasion of pathogens by knowing the main strawberry diseases. And their treatment will be more successful, and you will only have to enjoy good harvests. In addition, strong, high-quality seedlings will turn out from he althy material next year.
When choosing how to treat strawberries from diseases caused by a fungus, ask your friends gardeners what drugs are besthelp them. The meaning of this information is that in certain regions, pathogens are resistant to specific active substances of drugs, which means that the use of this chemistry will not be useful.
