Moniliosis is the most common disease of apricot orchards. The disease develops in two forms - affects the foliage and causes gray rot of the fruit.
Expect disease on the leaves after a warm winter. If the flowering period coincides with wet foggy weather - spores through the open pestle of the petal are introduced into the wood. At the same time the flower turns brown, the affected wood does not supply the sheet with food.
That is, moniliosis infection is the reason why apricot dries after flowering. The leaves do not fall off, mummified, but cracks appear on the branches, which the tree seeks to patch, highlighting the gum.
A measure to combat monal burns is cutting out damaged branches twice during the onset of the disease and after 2-3 weeks. Treatment with copper preparations will reduce the multiplication of the monilian fungus. Prevention - autumn whitewash garden with the addition of lime cuproxate.
Monilioz apricot and the fight against it will be required in the midst of summer, in a warm wet season. When the harvest is ready for ripening, the fruits are covered with a white, gray fluffy bloom, then rot. Such fruits need to be collected and destroyed. But in the winter trees are treated Bordeaux liquid three times. In the spring, before flowering, the garden is treated with a green cone, with buds of fungicides:
Treatment against insects is necessary, as they transfer rot to healthy ovaries.
Next year, a weakened plant should be freed from part of the crop, removing branches, thinning the plant. At the same time, this technique is prophylactic against fungal diseases.
Klyastersporiosis or perforated spotting
You are carefully examining through holes, looking for a leaf beetle, and in front of you is a fungal disease - apricot cloisterosporosis. Initially, there will be small bright specks pressed into the plate. Then there is necrosis, and a hole appears. If you do not take action - the spots become more, the sheet is destroyed. The source of the disease can be a fungus, an infection or a violation of agricultural technology. So, the leaves can be burned during preventive treatment, if you exceed the dose of chemicals, the tree can be weakened by infection. But if there are no other reasons, this is a mushroom, and the treatment is needed with fungicides. And the appeared wounds, where the gum oozes, need to be processed and closed with a garden pitch.

It seems, for no reason, even green or yellow fruits without taste begin to crumble, freeing the branches from the load. Why crumble apricot? There are many reasons. Perhaps the tree is overloaded with fruits and food is scarce. The owner did not regulate the load, and the exhausted tree gets rid of the harvest.
Probably, a hurricane wind passed through the site and dropped fruit. But temperature drops, damage to the barrel give the same result. A tree is waiting for apoplexy if the temperature has dropped to 0 degrees. The cell sap froze, the cells swelled, the leaves fluttered and wailed. After that, the affected tree begins to dry out and it is no longer up to the harvest. Bacteria and fungi invade the affected tissues. Treatment of apoplexy involves treatment with copper preparations, cutting of affected branches.
