What is wilt?

One of the dangerous fungal infections of plants -verticillary wilt. It has a short name - wilt. It is caused by a soil phytopathogenic fungus of the genus Verticillium.It is very tenacious, thanks to sclerotium - a special part of the mycelium, allowing it to survive in the most extreme conditions. Therefore, verticillary wilting of tomatoes, strawberries, peppers, potatoes, cotton becomes a rather complicated problem that is not easy to get rid of. It should be remembered that the soil affected by the wilt may preserve sclerotia for many years, while plant contamination will not occur. But under favorable conditions, the fungus will begin to develop, destroying the landing.

What does a wilt look like?

Verticillary wilting is a dangerous condition for plants. It is almost impossible to see it at the very first stages of development. But you can save at least part of the harvest, if you look closely at the plantings. The first visible signs of a wilt lesion appear on the lower leaves - they dry out. If you remove the affected fungus plant very carefully, without dispersing the spores of the fungus around, you may be able to save the rest of the planting. If you miss the onset of the disease, the wilt will be easy enough to recognize - the leaves of shrubs, vegetables, berries, flowers turn brown, dry, the stems become sluggish, as if wadded.The cut of the stem is decorated with small brown dots, which serve as absolute proof of the damage to the plants by this parasite. Meanwhile inThe strawberry withering, for example, does not affect the amount of the crop, if the berries have time to start growing until the plant dies, but the quality of the fruit is terrible - they all are affected by rot.

How does the infection occur?

Verticillary wilting of plants in the garden and vegetable garden develops due to the defeat of the plants by the soil fungus Verticillium. How does he harm plants? Everything happens very simply. From the soil where the mycelium is located, the fungus penetrates the roots of plants. This can occur both through microtrauma, and through special root hairs, increasing the absorbability of beneficial substances from the soil. Once in the root system, the fungus begins to grow, filling all the conducting vessels. The plant ceases to receive water and nutrients in the required amount and dries out. It is the mycelium of the fungus that develops in the conducting vessels of plants, and will be visible on the cut of the stem in the form of dark dots. This is a serious problem - verticillous wilting of strawberries. TreatmentSuch a disease will require a lot of strength and patience.

How does fungus harm plants?

Verticillary wilting of strawberries is an unpleasant problem, resulting in poor quality crops. Bushes are affected fairly quickly, so you can not have time to save the berries. After all, even if they managed to start and develop, the lack of nutrients due to the development of fungus in the plant will affect their quality - the berries will be covered with fungal rot. Penetrating into the root system, the fungus begins to grow actively. Mycelium increases in volume and fills the vessels in the stems through which the plant feeds. By blocking access to leaves, flowers or fruits, the fungus causes tissue damage, plants dry out, and berries become covered in rot. Verticillous wilting strawberry treatmentrequires immediate to maintain adjacent landings.

How to deal with fungal infections?

A serious problem for planting berries, flowers and vegetables is verticillary wilt. The treatment of this disease is complex, because the fungus is an underground resident. It can form sclerotia - the formation of mycelium at rest, allowing the organism to survive several years of unfavorable conditions for development and growth.It is necessary to fight with the wilt in a timely manner, because when spreading in the soil, it can hit a large number of plantings. Having noticed the first signs of a fungal infection, remove the plant as carefully as possible and burn it. It is probably impossible to cure already diseased plants, especially if we are talking about those whose fruits are eaten. So the easiest way to do prevention. What are the stages of the fight against fungal plant diseases?

  • crop rotation - planting the same crop on the same place is recommended in 3-4 years;
  • removal of diseased plants and plant debris from the land;
  • burning of all plant components in case of suspected fungal infection;
  • prevent the soil from drying out under crops, maintaining its humidity at a level of 85%;
  • irrigate plants with warm water - no less than 200, cold liquids cause rotting and development of fungal lesions;
  • strengthening plant immunity with phosphate-potassium fertilizers;
  • to process plantings and soil with fungicides, both purchased in specialized stores, and prepared independently on the basis of plants with antifungal properties. You can use tobacco, chamomile, charcoal.

These measures can prevent the defeat of planting fungus and further loss of the crop.

The Verticillium fungus is cunning, because it may not be aware of itself for many years and then destroy the plants if the disease is not noticed in time.
