Fusariosis, mainly affects ornamental plants and those found in the garden, no matter what age they are: young or adult must consider it a danger. It is a fungal disease, favored by hot-humid climates or by the presence of water stagnation. Also poor or infected soil can lead to the onset of fusarium disease as well as the recycling of infected containers.

Tomato fusariosis

One of plants most affected is that of the tomato. If it is not treated, it dies, a real problem for those who have a vegetable garden but especially for those who grow tomatoes in large quantities and who can see a large income fade.

Usually when the sick plant, the leaves begin to turn yellow, then they are affected by necrosis and fall off prematurely. However, another phenomenon can also occur: epinasty that makes you bend down the leaf blade. As symptoms become more evident, the risk of death of the entire plant increases and not just the compromised leaves.

Wheat fusariosis

When fusarium affects wheat, causes the drying of the ears and you notice it because while a part of the ear remains green, the diseased part becomes lighter. As maturation progresses, this symptom is less and less noticeable, which makes the disease even more dangerous. When fusarium is severe, leads to partial or total desiccation e it can even involve the whole ear and the terminal part of the culm.

Wheat fusariosis

Sick wheat has less vigorous seeds and accumulates mycotoxins.

Fusariosis: how to fight it

Before we had few weapons to fight it, everything changed when strains were discovered that were unable to cause disease to the plant but only to colonize its roots. This allowed the experts to study how to fight fusarium in a biological way and to control it while also allowing it to be prevented. We can already say that a correct use of fertilizers and the right amount of water makes plants more resistant to this disease.
