Dry Rot
Fungus
Type:
Risk to the plant:
INTERMEDIATE
Fusarium Solani / Fusarium Sambucinum
Pathogen:
Fusariosis
WHO CAUSES IT?
Fusarium solani and Fusarium sambucinum are phytopathogenic fungi that affect potato and other vegetable crops, causing a disease known as dry rot. These fungi can survive in soil and infected plant remains for long periods. Fungal spores are spread through contaminated growing tools, irrigation water, or direct contact with infected plants. Once they infect a potato plant, the fungi feed on the tissues, causing the tubers to rot.
