DESCRIPTION

WHO CAUSES IT?

Macrophomina phaseolina is a phytopathogenic fungus that causes the disease known as charcoal rot in potato crops. This fungus produces resistance structures called microsclerotia, which can survive in the soil and in infected plant residues for long periods, even under adverse conditions. When conditions are favorable, microsclerotia germinate and the fungus infects the roots and tubers of the potato, causing significant damage.

SYMPTOMS

Charcoal rot mainly affects the roots and tubers of potatoes. Symptoms include the appearance of dark, carbonaceous lesions on roots and tubers. These lesions can spread and cause tissue rot, affecting the quality and quantity of the harvest. In severe cases, the infection can cause wilting and death of plants.

• Dark, carbonaceous lesions on roots and tubers.
• Rotting of root and tuber tissues.
• Reduction in the quality and quantity of the harvest.
• In severe cases, wilting and death of plants.
