Causes of wilting cucumbers
When growing cucumbers, you can face the problem of wilting. In the article we will tell you in detail why cucumbers wither and what to do to solve this problem.
Causes of wilting cucumbers
Varieties of wilting
There are several types of wilting in cucumbers:
- Vertical wilt: the plant begins to grow sharply upward and loses most of its own leaves.
- Bacterial. The plant begins to die for no apparent reason. There is no yellowing or sluggishness of foliage.
- Tracheomycotic. There is a negative effect on the stem, roots and fruits of the plant.
A common feature is that they act on the crop from the soil. It is in this place that all causative agents of diseases are contained.
To decide what to do in such a situation, you need to understand the reasons.
Poor quality irrigation works
Cucumbers are considered finicky plants that need special attention. With the wrong watering, the leaves of the cucumber begin to turn yellow and fall off, after which the main stem withers.
Dry soil will not produce the desired yield, but water should be used in moderation. Excessive amounts of water can lead to root rot and pests.
It is necessary to carry out irrigation work every other day - then the situation will return to normal.
Incorrect fertilization
For the plant to develop, it is necessary to feed correctly.
If the cucumbers are actively withering and turning yellow, the feeding was wrong. Try spraying with manganese solution. It will allow for the prevention of diseases and parasites, and, if any, will help to get rid of them.
Improper fertilization can kill the plant
If the lower parts of the bush wither, then it is better to treat them with drugs called "Fitosporin" or "Trichodermin".
If the cucumbers wilted immediately after transplanting, then the reason lies in the insufficient amount of nitrogen components. Experts recommend adding poultry or cow droppings to the soil as a source of nitrogen. Remember that fertilizers are applied only to the root system. Do not spray the main stem with such solutions.
Plenty of sun
First of all, before landing, you need to choose the right place. Keep in mind that cucumbers thrive best in the shade. It is not recommended to plant them in open areas. A large amount of sun rays - may be another reason why parts of the cucumber began to fade.
The amount of harvest will decrease significantly if you grow cucumber crops in an open area not protected from the sun. As a preventive measure, you can use special sheds or grow cucumbers in greenhouse conditions. Film or glass reduces the risk of wilting in greenhouse cucumbers.
Influence of diseases and parasites
Fungal infections, most often cucumber mosaic, contribute to the wilting of the cucumber. Such fusarium wilts, in most cases, affect only plants in the greenhouse.This is characterized by the fact that in the Aftermath, not only the tops, but also the entire main part of the stem withers, starting from the upper part.
White rot is characterized by the fact that it immediately affects the root system. Gradually, the leaves begin to acquire softness. After a few days, the foliage completely falls off. Treatment of this disease involves the use of a drug such as Antopol. They need to spray the plant at intervals of 5 days until the disease is completely eradicated.
Among the parasites, the main 2 threats can be distinguished - aphids and spider mites. They are found only on the inside of the leaflet. Visual analysis of the cucumber plant is important. You can get rid of such parasites with self-prepared solutions from onions or manganese.
Conclusion
In order to answer the question of what to do if a cucumber withers, it is necessary to study all its features of care and cultivation. Once you have identified the true cause of the wilted cucumber, you must help the crop recover. An effective method of dealing with the problem is the use of specialized drugs.
