In the main, the ovaries are infected, which dry out at the end of flowering. With summer infection, even a perennial branch may die. On the fruit, the disease manifests itself as a darkened spot, which soon expands, the flesh becomes dark brown, and the fruit dries out completely. If an infected fruit comes into contact with a healthy one, it also becomes infected. The peak of the disease manifests itself in cold and wet weather during flowering. The pests are spreading the disease - the eastern moth and bud weevils. The main causative agent of the disease is the mushroom Moniliacinerea Bonord, which is in the marsupial stage. During the winter period, the fungus survives in the affected branches and, actively developing in the spring, it destroys entire branches. There are two ways to treat peach moniliosis. Subjected to infection branches and shoots burned, and the tree make rejuvenating pruning. Or you need to spray the flowers with 1% Bordeaux liquid. At the beginning of the growth of the fruit, the tree can be treated with a 90% solution of copper oxychloride. It is applied in four stages with a break of twenty days.

Fruit rot

Fruit rot is a disease that endangers the fruits of peach and nectarine. Small spots of gray appear on the visible part of the surface of the fruit, after which they grow over the entire surface, forming a completely rotten fruit. Infection penetrates through the damaged area left on the fruit by the moth or bud weevil. Sick fruit, in contact with healthy, infects it.

Excessive air humidity contributes to the active flourishing of the disease. The causative agent of the disease is also a fungus. The first rotten fruit appears in mid-June. The peak of the disease, which can cover the entire crop of the tree, comes at the end of August, before harvesting. The incubation period of the disease is extremely fast. From the moment of infection until the first signs appear it takes about five days. In the fight against fruit rot, it is necessary to destroy fallen fruits every day, and in the fall, in addition to the carrion, clean the tree from hanging damaged fruits. Before flowering, treatment with a Teldor or Topsin M fungicide is necessary.After flowering, the peach is sprayed again, processing will also be needed during the ripening of the fruit.

Peach Leaf Diseases

Peach leaves are also susceptible to various diseases. Treatment of peaches for diseases is one of the key points in the treatment of illnesses.

Klesterosporiosis (perforated spotting)

Peaches klyasterosporioz - a common disease that affects not only the leaves, young shoots, flowers, but also the fruits themselves.

Parts of the leaf, which hit the disease, dry up and die, leaving a hole on the leaf, which gave the name of the disease - perforated spotting. It also affects young shoots. Round orange spots appear on them, which then stretch along the cortex, after which yellow substance appears on them. Shoots affected by the fungus die off, and the whole branch may die. On fruits, it appears as small orange spots that darken over time.Affected fruit crust completely, forming cracks. Fruits with delicate skin are most at risk. The causative agent is a fungus, which is manifested in ulcers on flowers, branches and shoots. In rain and strong wind, the fungus is transferred to healthy fruits and, multiplying, can cover the whole tree. To stop the disease, before flowering, cut off all infected branches, processing the cut points with lime with the addition of copper sulfate, and cover with a layer of oil paint. Spraying of copper chlorine in the period of kidney swelling will also be an effective method. The next two spraying is carried out at the beginning of flowering and at the end.

Leaf curl

This disease manifests itself during flowering. Sick leaves take on a yellowish color, sometimes red with hints of pink. There is their deformation, darkening. Leaves grow in size, become brittle. Later on the inside, a white bloom is formed - a fungus, which is the causative agent. If the spring was rainy, the fruits of the peach can get sick.

Mealy dew is a serious affliction for many fruit plants. From it leaves and young twigs perish, and in peach the disease affects the fruits. The disease is recognized by white bloom on the fruit, which occupies almost half of its area. The early stage is not so easy to recognize, it appears on the inside of the leaf in early May. Infected branches stop developing, change shape, and some may even die. The disease reaches its peak of activity by mid-summer, especially during periods of severe weather changes, when long-term precipitations are replaced by hot weather. Effectively to fight the infection will help spring or autumn pruning of the affected branches. It is also worth paying attention to the fallen leaves and fruits.
