What is this attack? Why do apples rot on the tree from the inside? How to get rid of this disease, which is called "moniliosis"?
Causes of fruit rot
Most often, the fruit rot of apples appears in gardens that grow in a humid and warm climate. Moniliosis affects both the gardens of summer residents and industrial plantations.

First, small specks of brown appear on the fruits. Then all apples are covered with a crust, similar to small gray pads. Already at this stage of moniliosis, apples are unsuitable even for processing, as their pulp loosens and loses its taste. If the disease on the apple tree progresses closer to the autumn, then the fruits can acquire a glossy black color. Moreover, even when storing apples in a cellar, this disease continues to develop.
Methods of combating fruit rot
Unfortunately gardeners, apples affected by moniliasis, can not be saved. In this case, the rule "prevention is the best protection" is more important than ever. The processing of apple trees should be started already when the fruits in size reach the walnut and up to harvesting. During the period of active growth of apples, at least three treatments must be carried out, the last of which should be carried out no later than a month before harvest.
