    Attention: septoriosis!

    Raspberry white spot (or septoria) is a common fungal disease. Light brown spots up to 3 mm in diameter appear on the leaves, which then turn white and form a thin brown border around them. Black dots are visible on the spots - spores. Whitish spots with black dots appear on diseased stems. In these places, the bark is cracking. The leaves turn brown and dry up. Infected bushes do not bear fruit well and do not tolerate frost. What to do? In early spring, dig up the soil under the bushes. Before bud break, spray raspberries with Bordeaux liquid (300 g per 10 liters of water). Repeat the treatment before flowering (during the promotion of buds), as well as after harvesting raspberries (concentration - 100 g per 10 liters of water).

    Moniliasis

    The causative agent is a fungus - Monilia. Spread by wind, rain, insects.

    Symptoms
    The disease manifests itself in the form of monilial burn and fruit rot immediately after flowering. On the trees, flowers turn brown and dry, without falling off for a long time, then leaves, young twigs, ovaries. In rainy and warm summer weather, brown spots appear on the fruits, gradually growing and, in the end, covering the entire fruit. Small ash-gray pads are noticeable on their surface - accumulations of fungal spores that penetrate through mechanical damage.
    At low humidity and temperature, or, conversely, in hot, dry weather, the pulp of the fruit darkens and dries out, turning into a thin skin that envelops the bone. Such affected fruits remain hanging on the branches for a long time and are the main source of the disease.

    RESISTANT TO MONILIOSIS
    Varieties are considered relatively resistant to this disease.
    Common cherry: Anadolskaya, Griot Rossoshansky, Cossack, Favorite, Melody, Radonezh, Ryazanochka.
    Cherry felt: Altana, Pink Harvest.
    Apricot: Amur, Dzhengutayevsky, Musa, Advertising, Northern Triumph, Ulyanikhinsky, Late Untsukulsky, Uralets, Black Velvet, Amber of the Volga region.
    Sweet cherry: Jeannette, Caucasian, Olenka, Sadko, Chermashnaya.
    Cherry plum: Globus, Evgenia, Zhemchuzhina, Sigma.

    PROTECTION MEASURES
    Completely cut out the affected shoots with the capture of 3-5 cm of living tissue, covering the sections.
    Treat as from coccomycosis - carry out 2-3 sprayings.
    After harvest, destroy damaged fruits.
    Avoid mechanical damage to wood.

    KOKKOMIKoz

    The causative agent of the disease is a fungus - Coccomyces hiemalis. The spores are spread by rain and wind, and persist on fallen leaves.

    SYMPTOMS
    On the leaves of cherry and sweet cherry, small reddish-brown spots appear on the upper side, a pinkish-white coating of sporulation forms on the lower side, the leaves begin to turn yellow and fall off. Sometimes petioles, stalks and fruits are affected, on which fuzzy brownish necrosis appears.

    PROTECTION MEASURES
    The first treatment is done in the bud phase, then after flowering, at intervals of 15-20 days with preparations - Bordeaux mixture, Abiga-peak, Skor, Topsin-M, Indigo KS or cuproxate and others.
    Improve the conditions for the development of trees, using foliar top dressing with microfertilizers - on the leaves - preparations containing a complex of basic nutrients. Can be used for spraying "Siliplant", "Zircon" - 0-5 ml per 1 l of water, "Epin-Extra" - 0-10 ml per 2 l of water, or add them to the tank mixture with a fungicide to reduce negative impact on plants.
    Be sure to remove the affected leaves in the fall.

    Why Pears Cracked
    Almost all the pears in my garden are cracked or rotted on the trees. Why did this happen and what can be done now?

      The main causes of pear fruit rot are scab fungal diseases and fruit rot (moniliosis). The source of infection is diseased fruits that have overwintered on trees. They fall or remain hanging, holding tightly to the branches. All mummified fruits must be cut off. Do it after the fall.
      But the cracking of the fruit is most often caused by stressful physiological causes. Often this happens if it rains after a dry period. The spores of pathogens immediately fall into the cracks, causing rotting of the fruit. Their cracking can be avoided by organizing uniform watering of the pear. And if this is not possible, then you need to try to keep the spring moisture as long as possible by mulching the soil under the crown.
      To suppress a fungal infection, spray fruit trees with a 5-7% solution of urea (500-700 g per 10 liters of water, 10 liters are consumed for every 2,5 sq.m). It is necessary to spray at the beginning of leaf fall, too late may not have an effect.
