Why pear leaves curl and what to do, treatment and processing
The leaves of a pear can curl for various reasons. But most often this happens due to improper care and the appearance of diseases or due to pests. This is a serious problem that has a negative impact on future yields.
Main reasons
Foliage curling is a common problem for many summer residents who have fruit trees in their garden. The main reasons why this happens include:
- Improper care.
- Lack of moisture in the soil.
- The tree does not get enough nutrients from the soil.
- The roots froze over the winter.
- The appearance of diseases or insects on the plant.
- Young leaves are curled due to the appearance of 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.
Nutrient deficiency
Nutrient deficiencies often cause yellowing and curling of leaves on the tree. This problem is the easiest to solve. It is enough to organize a schedule for the introduction of mineral and organic fertilizers from spring.
Fungal diseases
Fungal diseases include:
- scab;
- powdery mildew;
- rust;
- brown spotting;
- black cancer;
- cytosporosis.
The danger of fungal diseases is associated with 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 leaves curling into a tube. Then they begin to blacken 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;
- furrowing of wood.
The causes of pear viral diseases are the appearance of insects, unicellular microorganisms and fungi.
Insect Invasion
The second reason for the appearance of twisted leaves is harmful insects.
Aphid
If ants appear on the site, it means that aphids will soon appear. From aphids, a pear before the appearance of buds is sprayed with the preparation "Kinmiks" and "Agravertin" before flowering. The last spraying is done after the fruit set. The biological product Iskra is used.
Pear honeydew
Pear honeydew not only spoils the tree, but also contributes to the appearance of sooty fungus.As a preventive measure, immediately after the foliage falls off in the fall, it is burned. In addition, during the fruiting season, mineral fertilizing is added to the soil. To get rid of the sucker, 2 weeks before flowering, the pear is sprayed with organophosphorus preparations.
Mite
Ticks feed on the sap of young leaves. First, brown spots appear on them, and then they fall off. For prevention, the plants are regularly thinned out and some of the branches are cut off. The cut sites are disinfected. If insects have already appeared, the trees are treated during the budding period, during flowering and after harvesting the fruits with sulfur-containing and phosphorus-containing preparations.
Leaf roll
"Karbofos", "Iskra" and "Landing" help from the leaf roll. The danger for the pear is the larvae, which do 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 health of the tree. In addition, it is important to prune trees twice a year and prevent weed growth.
Tree treatment
What to do if damaged leaves begin to appear on the plants? As soon as twisted leaves began to appear on the pear, it is important to immediately start treatment so that later you do not have to cut down the entire garden.
Chemicals
Among the chemicals are effective against diseases:
- Horus;
- Abiga Peak;
- bordeaux liquid;
- "Speed";
- Rayek.
Also, spraying with copper sulfate or copper oxychloride helps with pear diseases. For powdery mildew, trees are sprayed with Topaz.
Folk
It is possible to treat plants from pests and diseases using traditional methods, which are not worse than chemicals in efficiency. The advantage of folk recipes is that they are safe for humans and animals.
Herbal infusion of celandine
To prepare the infusion, take 1 kg of fresh raw materials and 500 g of dry celandine. Raw materials are poured with a bucket of warm water and infused for 12 hours. Before spraying the plants, the infusion is passed through cheesecloth to cleanse the remains of the grass.
Wormwood infusion
The infusion of wormwood helps to get rid of insects, since they cannot stand its smell. Fresh wormwood is poured with warm water and infused for 24 hours. Then it is poured into a spray bottle and the pear is processed.
Infusion of tomato tops
In the fall, after harvesting tomatoes, the tops can be used as a remedy for pear diseases. To prepare the infusion, tomato tops are poured with 1 bucket of water and left for 2 days. The plants are sprayed with the finished infusion in the fall after harvesting the fruits.
Horsetail decoction
Horsetail decoction is used for rust. Pour 1 kg of fresh raw materials with 10 liters of water and leave to infuse for a day. The next day, the infusion is boiled for half an hour over low heat. When the broth cools down, dilute it with water and spray the plants. The pears are poured with the rest of the broth.
Potassium permanganate solution
A solution of potassium permanganate helps fight powdery mildew. But it is effective in the initial stages of the disease. 4 g of potassium permanganate is diluted in 10 liters of water and the foliage is treated. It is also worth watering the soil around the trunk.
Dandelion broth
Pour fresh grass and dandelion inflorescences with water and put on low heat for 20 minutes. When the broth has cooled, the foliage of the tree is treated with it.
Potato infusion
Infusions based on potato tops help to get rid of aphids, mites, leaf rollers and moths. To prepare the infusion, 1 kg of fresh tops are crushed and poured with water. Insist in a warm place for 5 hours. Before processing the plants, grated laundry or tar soap is added to the infusion. It is advisable to spray pear with infusion in the evening. It is also worth looking at the weather forecast in advance so that it does not rain in the coming days.
Tobacco infusion
Tobacco infusion is effective against insects.Fresh tobacco is crushed and filled with a bucket of water. Insist for two days. Pass through cheesecloth and dilute with water. Spray in the evening in calm dry weather.
Onion broth
Pour onion skins with water and bring to a boil. Spray the pear with broth several times a week.
How to prevent?
To prevent the appearance of diseases and pests, the pear is regularly pruned. Sanitary pruning is done in the fall. All cut branches are destroyed away from the site.
Several times a season, the area where pears grow is weeded and weeds are destroyed. Regular feeding is also important. Organic and mineral supplements increase plant immunity. At the first sign of infection, action must be taken immediately. If you do not start treating the pear in time, you can lose not only the harvest, but also the tree. Many diseases at an advanced stage do not respond to treatment.
