Reasons for the appearance of black bloom on gooseberries
The most common cause of black bloom on gooseberries is disease..
Powdery mildew - a fungal disease that affects young and adult shrubs - appears due to soil contamination, sudden changes in the weather, non-compliance with the rules of care. The berries are first filled with white rot, and then dry out and darken right on the bush. It is impossible to save gooseberries at the blackening stage.
Also gardeners secrete alternaria (black spot)... The disease first affects the leaves - gray spots appear, which may darken over time. They grow and merge, which is why the leaf looks like a burnt one.
Alternaria appears in the middle of summer, when the weather is hot or there are heavy rains. The cause is disease and plant thickening.
Small brown spots with dark shiny tubercles may appear on the bush.... This is how the anthracnose disease manifests itself. If the disease is not detected in time, the spots grow, and the leaves dry out and fall off. Anthracnose activity peaks in mid-summer.
Attention! Dark spots or the appearance of black plaque can be caused not only by diseases, but also by mistakes in agricultural technology. Among them, there is a lack of dressing, excess or deficiency of moisture, treatment with drugs that have expired.
