Pear leaves curl: why and what to do, how to treat and how to process

Pear leaves can curl for various reasons. But most often this happens due to improper care and the appearance of diseases or because of pests. This is a serious problem that has a negative impact on future yields.

Main reasons

Twisting foliage is a common problem for many summer residents who have fruit trees growing in their garden. The main reasons why this happens include:

Improper care.
Lack of soil moisture.
The tree is not getting enough nutrients from the soil.
During the winter, the roots froze.
The appearance of diseases or insects on the plant.
Young leaves curl up due to viruses and larvae.

In a pear seedling, the leaves often begin to curl due to weak immunity or a violation of the technology of planting in a permanent place.

Nutritional deficiency

Nutritional deficiency is often the cause of yellowing and curling of the leaves on the tree. This problem is the easiest to solve. It is enough to organize a schedule for the application of mineral and organic fertilizers in the spring.

Fungal diseases

Fungal diseases include:

scab;
powdery mildew;
rust;
brown spotting;
black cancer;
cytosporosis.

The danger of fungal diseases is due to the fact that fungal spores quickly spread throughout the garden. If measures are not taken in time, then after a while all the trees in the garden will be infected.

Bacterial diseases

Bacterial diseases include fire blight and root cancer. The first sign of a bacterial disease is leaflets curling into a tube. Then they begin to turn black and fall off.

To prevent disease, weeds are removed in time and insects are destroyed. In addition, pears are fed with mineral fertilizers.

Viral diseases

Viral diseases include:

mosaic disease;
witch's broom;
grooved wood.

The causes of pear viral diseases are the appearance of insects, unicellular microorganisms and fungi.

Insect invasion

The second reason for curled leaves is harmful insects.

Aphid

If ants appeared on the site, it means that aphids will soon appear. From aphids, a pear is sprayed with Kinmiks and Agravertin before flowering before buds appear. The last spraying is done after fruit set. They use the biological product "Iskra".

Pear sucker

Pear sucker not only spoils the tree, but also contributes to the appearance of soot fungus. As a preventive measure, immediately after the leaves fall in the fall, they are burned. In addition, mineral fertilizers are added to the soil during the fruiting season.To get rid of the sucker, 2 weeks before flowering, the pear is sprayed with organophosphate preparations.

Tick

Ticks feed on the juice of young leaves. At first, brown spots appear on them, and then they fall off. For prevention, plants are regularly thinned out and cut off part of the branches. The cut sites are disinfected. If insects have already appeared, the trees are treated during the period of bud emergence, during flowering and after harvesting the fruits with sulfur-containing and phosphorus-containing preparations.

Leaflet

Karbofos, Iskra and Landing Forces help from the leaflet. The danger for the pear is the larvae, which cause the main damage to the tree.

Improper care

Leaves can also curl into a tube due to improper care. Rare watering, lack of nutrients in the soil negatively affects the he alth of the tree. In addition, it is important to prune trees twice a year and prevent weed growth.

Treatment of a tree

What to do if damaged leaves begin to appear on plants? As soon as twisted leaves begin to appear on the pear, it is important to start treatment immediately so that you do not have to cut down the entire garden later.

Chemicals

Among chemicals effective against diseases:

"Chorus";
Abiga Peak;
Bordeaux liquid;
"Quick";
Ryek.

Also, spraying with copper sulphate or copper oxychloride helps with pear diseases. From powdery mildew, trees are sprayed with Topaz.
