Why pears rot - the main reasons
Pear fruit rot is a symptom of a number of diseases. Each of the pathologies has its own distinctive features of manifestation and characteristics.
Scab
The disease occurs mainly in the summer, but in some varieties it can also occur in the fall. Scab features:
- the fruits take on an irregular shape;
- the color of pears is weak or completely absent;
- if the fruit is ripe, it will not lie for a long time, after a few days it will start to deteriorate from the inside;
- the fungus affects not only the fruit, but all parts of the tree, leaves, trunk, shoots and flowers.
If the scab is not stopped in time, this can lead to a slowdown in the growth of the pear tree, to its oppression and death.
Fruit rot or moniliosis
The disease is triggered by a microscopic fungus. Its spores penetrate into the fetus when there is a small scratch on it.
Moniliosis can quickly spread from pears to other horticultural crops. The fungus affects trees growing densely in unkempt gardens. Direct sunlight kills fungal spores. The main sign is that the fruit rot from above, then inside, completely covered first with black dots, then with a brown bloom with growths.
Old trees
The older the tree, the worse its metabolic processes occur, the amount of nutrients decreases, the plants wither. This negatively affects the quality of the crop.
Pears are weak, do not lie for a long time, can quickly rot after ripening and burst. This process begins with the tail, when the fruit is still on the branch.
Peduncles
The stalks are the most active pests on the pear. Due to the fact that the stalks move inside the pulp, this leads to the fact that the pear begins to crack. An infection gets through the cracks, which causes putrefactive processes
The fruit changes its color to a gray tint, disappears and becomes unusable.
Weevil beetles
Beetles - weevils start on the shoots and gradually damage all parts of the pear:
- leaves and buds;
- inflorescences and fruits;
- wood;
- petals, young, fragile shoots.
An indication of the presence of weevils is that the pear suddenly begins to turn black. If you do not have time to notice this symptom, the disease will rapidly develop throughout the plant.
How to deal with pests and diseases
