First Report of Colletotrichum graminicola Causing Maize Anthracnose in Galicia, Northwestern Spain.

Maize (Zea mays) is one of the most important crops worldwide, and fungal diseases are responsible for major losses in food production. Anthracnose caused by Colletotrichum graminicola can infect all maize tissues, although stalk rot and seedling blight cause more significant economic damage (Munkvold and White, 2016). Anthracnose stalk rot is characterized by a distinctive external blackening of the lower stalks resulting in large black streaks, while the pith turns dark brown and has a shredded appearance.
