Strawberry diseases

Gray rot affects leaves, buds, flowers, green and ripe berries. It appears in the form of brown, rapidly expanding spots. On

decaying berries is a gray fluffy coating, which is a congestion of fungus spores. Raw, rainy weather contributes to the development of gray rot. The mushroom hibernates in the soil, on plant remains. Stronger are affected by thickened plantings in low, poorly blown places, and also varieties with berries growing close to the soil. Control measures. A fruitful, well-ventilated part of

side up, brown at the edges and dry out. The distinguishing feature of phytophthora wilt is the reddening of the root of the root, especially at its apex,and later on-drilling and decomposition of the affected tissues. The whole process lasts a week( sometimes only 2-3 days). .

The fungus can also cause a skiny rot of berries that infects large berries: they show a waterystains that do not have a sharp border with a healthy tissue. The color of the spot becomes lighter( sometimes the color may change to purple or purple, for example, in the varieties "Zenga Zengana" and "Zenith").The flesh becomes dense, rubbery, gets a bitter taste. Control measures. Predecessors of strawberries for 1-2 years should be onions, garlic, parsley or dill. To prevent the development of rot, use the old folk remedy: before the ripening of berries under the bushes, lay straw. When detecting shrubs with signs of wilting, they must be immediately removed and destroyed.

Verticilliosis wilt, caused by the defeat of the vascular system of plants in the soil by the fungi, manifests itself as a distinct yellowing or reddening followed by leaf drying in the middle of summer.

Along with strawberries, tomatoes and cucumbers are affected.

Control measures. It is necessary to pour a solution of 1% Bordeaux mixture( 100 g per 10 liters of water), consuming 0.5 liters per well.

Powdery mildew is a white coating first from the underside of leaves, then on petioles, ovaries and berries. It develops in strongly thickened and clogged plantations of strawberries, with excessive watering and top dressing. Control measures. To destroy the affected parts of plants, timely implement agrotechnical measures, use healthy planting material. After harvesting, sprinkle with 1% Bordeaux mixture( 100 grams per 10 liters of water).

Spots( white, brown, brown)

mainly affects the leaves. The causative agent of the disease is the fungus, which causes the appearance of various spots on the leaves. The infection remains on the affected leaves.

Control measures. Cleaning and burning or composting of dry leaves. At the annual occurrence of the disease, it is recommended that before the flowering and after harvesting, the plantation is sprayed with hom( 40 g per 10 liters of water).
