Gardeners have to contend with various problems when growing fruit trees. Very often they don’t know what to do if the pear branches dry out one by one. What kind of disease is this and what are the treatment methods is the topic of the article.
Possible reasons why the pear dries out
It is not always possible to immediately determine the exact cause. This is due to the fact that she is not alone. Often several reasons combine and simultaneously affect the tree. Even in the same area, fruit crops react differently to the same conditions.
To find the reason why the pear dries out, you need to know the main factors. Among them it should be noted:
- Incorrect planting and poor follow-up care. All gardeners are aware of the pear tree’s demands for compliance with planting rules. If during the period of frost the soil pushes the seedling upward, the root collar is exposed, which leads to the drying out of the pear. The second reason for exposure may be improper placement of the seedling during planting.
- Weather. In this case, the cause will be the condition of the root system.During the rainy season, the roots do not have enough air, they begin to rot, then die. Dry summers lead to dehydration of the soil, which also causes parts of the tree to dry out. The second factor is return frosts during the flowering period of the pear. Plant tissues freeze and then dry out. Also, at the beginning of winter, the roots may freeze, because the pear is not a frost-resistant crop.
- Impact of pests and pathogenic microorganisms. Various diseases and pest invasions can damage the tree and lead to drying out of parts or the entire pear.
Why do pear tree branches dry out?
There are some reasons why pear branches dry out. It is important to pay attention to the timing of the problem. If the branches begin to dry in the spring, then this may be a manifestation of a terrible disease - bacterial burn. The first stage appears on buds and flowers, then moves on to leaves and branches. Treatment should be for fire blight.
If the problem appears in the summer, the cause may be hydrothermal or sunburn. This is not a disease, but the consequences of exposure to high humidity or air temperature and direct sunlight. The seedling should be protected from adverse factors.
Another climatic factor is frostbite. Frostbreakers can destroy even large, strong pear branches. Therefore, it is necessary to properly insulate the tree before the onset of winter.
Pear branches also dry out due to damage to the bark or the presence of pests. If these are moles, then there are ways to combat them. Treatment with Aktara helps against small pests.
Why does the top of a pear dry out?
This problem is often called dry top. Most often, drying out of the upper tier occurs in the spring, but can appear in the second half of summer. The problem repeats itself every year. Young seedlings may die after 2-3 years, mature trees reduce productivity. There may be several reasons why the top of a pear dries out:
- Violations of agricultural technology. This is especially true for the process of planting and care. Most often, the drying out of the tops is associated with the proximity of groundwater. The roots of a young pear reach the water, begin to rot and die. Then the top dries out. If a young pear seedling is planted correctly, the top will dry out last. This is how the cause is determined that is not related to landing problems.
- Agrochemical violations – nutrition, diseases, pests. At the end of summer, the tips of new branches of a young pear dry out. If you carefully examine the shoots, you can see where the corrosive wood has invaded - the cause of drying out. The ends of the shoots are also killed by the eastern codling moth.
The gardener needs to cut out the part of the top that has shriveled. Thus, the balance between the root system and the crown will be restored. If groundwater is close, you will have to replant the pear seedling higher or install a good drainage system.
Why do pear leaves dry out?
This manifestation occurs very often.
Determining the cause is not always easy. Since there are many of them, it is necessary to consider all possible ones:
- Unsuitable climatic conditions for the tree. Most varieties of pears are very resilient to drought and high temperatures. But some are bred for cultivation in regions with cool climates. Therefore, it is necessary to take into account varietal characteristics.
- Incorrect care. This category includes a watering schedule, regularity of fertilizing, and sufficient lighting. Excessive or insufficient watering leads to negative changes in the root system. The pear ceases to receive sufficient nutrition and moisture. The leaves react and begin to dry out.
- Fungal infections. These include a large list of diseases, the most common of which is scab. Fungal diseases can only be treated with special medications and preferably as early as possible.
- Pests. Serious lesions even lead to rapid loss of foliage, and not just drying out.
Young pears are considered whimsical and even capricious trees. Without sufficient care it can dry out very quickly.
Why do pears dry on the tree?
The most likely cause is moniliosis, a fungal disease.
Carriers of infection are birds, insects, and wind. Some of the fruits affected by moniliosis fall off, the rest dry on the branches. The second name of the disease is fruit rot. It develops during periods of increased heat and humidity. Preventive measures are necessary - pruning, removing diseased fruits, spraying the pear at a certain time of development.
Another reason is considered to be insufficient nutrition of the pear seedling and incorrect watering schedule.
How to save a pear that is drying up
The first step is to determine the exact cause of the drying out. Of course, if possible. When this is not possible, then check each item listed earlier in the article.
Chemicals
Treatment with chemicals is used in the presence of fungal diseases on the pear or the appearance of pests. It is easiest to fight if the necessary preventive spraying has been carried out.For therapeutic treatments, copper-containing preparations or fungicides are used. Among modern drugs, antibiotics stand out, which are very effective in drying out pears. Insecticides work against pests:
- Bi-58;
- Decis Profi;
- Tetrix;
- Aktara.
The solution is prepared strictly according to the instructions, then the wood is treated. Several repeated treatments may be necessary to get rid of the problem. You need to carefully monitor the condition of the pear. Chemical control agents are not used after the tree has finished flowering.
The instrument must be disinfected before and after the procedure.
Biological agents
Currently, new modern biological drugs have appeared. They have not only therapeutic effects, but also therapeutic and prophylactic ones. A one-time treatment is not enough. Biological agents are most often photounstable and quickly decompose when exposed to light. The Fitoverm series works well for exterminating pests. This group also includes Aktofit, Iskra-bio, and Agravertin.
Gamair, Alirin-B, Planriz, Fitosporin-M are used against fungal infections and for prevention purposes. Protection against rodents is Bactorodencid.
Traditional methods
Wood ash is considered the most common substance for folk compositions. It serves as feeding and protection against pests. In the form of an infusion, it is used for spraying; dry powder is sprinkled on the branches and around the trunk.
An infusion of garlic or onion is prepared against ticks, aphids and as a preventive measure for fungal diseases. It is not necessary to clean the cultures; the husks are also suitable for preparing infusions.
A solution of baking soda is used much less frequently, but it is used at the first signs of powdery mildew or fungal infections of foliage.
It is effective to use infusions of nutty autumn leaves, tobacco, and wormwood. All these funds are aimed at preventing and controlling pear pests.
Rules for caring for a fruit tree
A very important point for maintaining the health of the pear. The gardener needs to pay attention to the plant at every stage of its development.
- Be sure to check the condition of the soil. Pears need loose, fertile soil. On heavy clay soil, the roots will quickly begin to rot.
- Make drainage outflows if groundwater is close or transplant the young tree higher.
- Regularly prune and shape.
- Remove damaged branches or leaves.
- Keep the soil moist and follow the watering schedule.
- Feed the fruit plant in a timely manner.
- Be sure to draw up and implement a schedule of preventive tree treatments. Spraying should be done not only against pests, but also against possible infection of the pear.
- Carefully inspect the tree regularly.
- Cover the tree before frost sets in to avoid freezing of the roots or the appearance of frost holes.
- Protect from rodents.
Conclusion
If a gardener notices that pear branches are drying one by one in the garden, you need to take action right away.
There are several reasons for drying out. To save the tree, you will need to strictly adhere to cultivation techniques from the moment the seedling is planted.
