Fusicoccum is a genus of fungi that primarily affects plants, particularly those in the family Ericaceae. It is known for causing diseases such as canker and leaf spot, which can lead to significant damage in affected plants. The fungi thrive in warm, moist environments and can spread through spores. These fungi are often studied in the context of plant pathology, as they can impact agricultural productivity. Understanding Fusicoccum helps researchers develop better management strategies to protect crops and maintain healthy ecosystems. Effective control measures may include proper sanitation and the use of resistant plant varieties.
