What is Fusarium wilt?
The disease is not completely curable, its spread can be slowed down or prevented with the help of preventive measures. Infected bushes must be removed from the site and burned.
External signs
The first sign is yellowing of the upper foliage and a slight loss of moisture. The leaves become dark, acquire a yellow-brown color. Stems thin and weaken. Damaged areas are covered with pinkish spots. Thus, the fungal mycelium of the disease manifests itself.
Fusarium damage
Because the fungus is located in the ground, the plant becomes infected from the roots. The pathogen enters the pepper through the vessels through the roots and gradually enters the leaves. As a result, a blockage occurs in the vessels, while nutrition is disturbed, and the plant is poisoned with toxins.
As a result, the vitality of pepper decreases, and additional ailments may appear.
Fightwith fusarium
Depending on the stage of infection of the plantings, one of the following disease control measures or a combination of them can be used. It should not be forgotten that some chemical elements cannot function with each other.
Chemicals
Most often, these funds are used with a significant lesion. They, of course, help to stop the development of the fungus, but they harm the pepper and the soil.
Fungicides include:
- "Quadris";

They can be used in the following ways:

- steam treatment of seeds and premises.
Biological agents
Fusarium is used against such biological preparations as:

Potassium humate refers to organomineral fertilizers. It is added to the soil.
Folk ways
Against fusarium, you can use folk remedies:

Pumpkins and cabbage are considered the best predecessors in the beds. It is important to systematically add organic matter during the period of cultivation of previous crops. If you are going to cultivate only one pepper, plant a cereal crop (barley, rye, oats) in a free area.
The root system of green manure releases substances that destroy the fungus. The green mass is then crushed and plowed.
