Threat to blueberry production in Morocco

The fungus Erysiphe vaccinii, responsible for the disease known as powdery mildew, threatens blueberry production in Morocco and around the world. This is according to a study conducted by North Carolina State University.

There are two strains of this fungus originating from the eastern United States and identified in several regions of the world including Morocco, Peru and Portugal: one attacked blueberry plantations in China, Mexico and California , and the other, more virulent, spread to the Maghreb, particularly Morocco, and southern Europe.
