Pear leaves turn red: causes, treatment
If the leaves of a pear turn red, you must act immediately. This phenomenon depends on various reasons - from temperature changes to serious illnesses. There are 2 ways to deal with this problem - chemical and folk.
Causes of reddening of leaves in a pear
Causes of redness
The first action of every gardener is to determine the reason why the leaves of pears turn red. They can be like this:
- Strong temperature changes. Very often, pear leaves turn red in summer from extreme heat. Another situation is the influence of rapid temperature changes. Only abundant watering can help the tree in this situation.
- Lack of phosphorus. At first, the foliage of the pear turns red in small spots, which gradually become larger. And after 3-5 days the entire leaf becomes red. Another manifestation of a lack of phosphorus is that the leaves turn red from bottom to top.
- Very frequent and abundant watering of the plant. The fruit tree does not tolerate excess moisture. Therefore, redness can provoke excessive watering or groundwater if they are close to the roots of the plant. Strong humidity does not allow air to come to them, and the tree stops breathing.
- Very deep planting of the seedling. When planting, the neck of the seedling should be flush with the ground. Otherwise, if the roots of the plant are very deep, then it will begin to rot. This will lead to inhibition of sap flow. As a result, the leaves will begin to turn red and curl.
Another reason is various diseases. Pests and diseases infect the tree, which can provoke redness.
If the leaves of a fruit tree reddened unevenly and in large spots, then it was struck by a black cancer. This is a disease that destroys the pear completely. And after a few years, it can lead to the complete death of the plant.
The pear can also be damaged by various fungal diseases. The main thing is not to ignore them, but to fight urgently, and then you can save the plant.
Ways to fight
Redness of foliage cannot be ignored. Even with the slightest manifestations, you need to begin to eliminate the disease. The main methods are chemical treatment and folk remedies.
Traditional methods
This method is the most harmless. It is most often used in the fight against aphids, the most common pest that contributes to the appearance of redness.
Aphids multiply rapidly. And to stop its destructive effect, use a herbal tincture of celandine.
To prepare it, you need to take 4-5 branches of celandine. Grind them (be sure to wear gloves) and add to 1 bucket of boiled water. The infusion should be covered and left in a warm place for 5 days. For the solution, you need 200 ml, which must be diluted in 10 liters of water.
Spraying with this agent must be carried out 3-6 times (depending on the number of pests). The average interval is 5 days.
Chemical treatment
Processing will help save the tree
With an insufficient amount of phosphorus, mineral fertilizers must be applied.The culture should be sprayed 2-3 times a week with Ammophos solution. Its advantage is that it dissolves well in water.
This treatment can be carried out only 2 - 2.5 months a year immediately after the detection of a lack of phosphorus. It is done even when the redness of the spruce is visible.
For the purpose of prevention, the culture can be treated with the following drugs:
- Azophos. It can be used in the spring as a preventive measure against all diseases and pests. Dosage according to the instructions - 100 ml per 1 bucket of water. The solution is prepared immediately before use.
- "Speed". This drug is used only before flowering, so as not to harm the pear. It is necessary to dilute 5 ml in 10 liters of water. On average, consumption per plant is 1 liter of solution.
- Delan. The drug is intended to increase the level of plant safety against the influence of pests. In most cases, it is used after flowering. Consumption - 1 kg / ha. Enough 3 treatments to completely eliminate the pest.
Chemicals are recommended to be used only in emergency cases when there is a serious threat to the plant and traditional methods do not help solve the problem.
Prophylaxis
In order for the tree to be resistant to various diseases and pests, timely care must be taken. But it happens that even with high-quality robots, the foliage begins to acquire a red color.
This could be due to the landing site. If the plant is in a wetland, it must be transplanted. But this can only be done with young seedlings, which need to be dug up along with the soil on the roots and planted in a place with a lower humidity level. And near old trees that are more than 6 years old, it is better to make ditches to drain excess water.
It happens that the seedling is planted too deeply, which negatively affects the condition of the plant. In this case, it is necessary to transplant the tree into a shallower hole and cover it with more earth from above.
If the plants are already infected
Agrotechnical methods give good results in the fight against black cancer, because of which pear leaves turn red. For treatment, you need to act like this:
- remove the infected bark from the tree trunk;
- remove reddened leaves;
- cut off branches that are damaged by a pest;
- burn everything that was cut off.
After carrying out these activities, there is a great opportunity to save the plant.
The key to the success of agrotechnical techniques is their correct and timely implementation.
