Leaves suffer from diseases, fruits, flowers and even the bark of the plant. In this article we will talk about it, existing pests and diseases of quince, and how to treat the plant.

quince disease

Why quince dries or why quince blooms, but does not bear fruit - the most common questions of gardeners, who grow this plant. The answer is one: most likely, your tree is sick. Of course, the most terrible diseases are various forms of cancer (affects the bark), in which the bark of the plant recedes and bursts.

If the bark is all right, and it does not peel off, did not recover and did not burst, you can rest easy, the plant can be saved. If you noticed, peeling bark - it is better to get rid of the plant without delay. There are many diseases besides cancer, to which the quince tree is exposed, and now we will consider them in more detail.

moniliosis

This is a common fungal disease, which is caused by high humidity. Fruits suffer first of all from a disease, which already have various mechanical damages. Brown spots begin to appear on them, which increase very quickly in size. Quince fruit becomes loose, loses all taste and falls to the ground.

What to do to combat the disease? You can use copper sulfate and Bordeaux mixture, as well as drugs "Teldor" or "Rovral".

drilling leaves

Many farmers are wondering: why quince does not bear fruit? Another popular question: why not all is well with fruiting, if the tree looks perfectly healthy? If Japanese quince does not bear fruit, and the flowers on the branches withered and fell, most likely, you are dealing with drilled leaves. Another symptom of this disease is drying of the tips of the shoots. Sometimes quince fruits can still appear, but soon they rapidly turn black and fall off.

What to do, to save the tree? First of all, remove all infected items and burn them. After that, you can treat quince with a remedy, like Oxyhom (or similar means).

Powdery mildew

Initially, the ends of the branches are covered with a pale red plaque. If no action is taken, soon the plaque will turn into a thick film, on which the bodies of the fungus-pathogen will be clearly visible. The consequences of this disease are quite sad: withered shoots stop growing, the leaves turn yellow, deform and dry up, and the plants themselves stop flowering and slowly dry.

rust

At first, small orange bumps appear on the leaves, and pustules form on the underside. Eventually, such a bump cracks, and fungal spores spread throughout the county. You may also notice, that the leaves turned yellow and fell very quickly.

To get rid of the infection, various kinds of fungicides are used.

ovarian rot

This disease begins with the appearance of small dark spots on the leaves, which gradually increase in size. Disputes can also get into the buds and ovaries, why flowering stops.

Get rid of the disease by removing all infected parts of the plant, and then carry out treatment with "fundazole".
