Fusarium circinatum (teleomorph: Gibberella circinata) is a highly virulent pathogen affecting pines and causing damping-off in plant nurseries and pitch canker in forests. While G. circinata is present in the EPPO region but not widely distributed, it is currently included in the A2 list of European pests recommended for regulation as quarantine pathogens. The most common symptom of pitch canker in adult pines is a bleeding, resinous canker present on the main stem, terminals and large branches. Importantly, cankers on the main stem prove lethal when the stem is girdled, and this pathogen is also responsible for damping-off, shoot die-back and the death of seedlings in nurseries. Spain was the first European country to detected pine pitch canker. This occurrence was reported over ten years ago and more recently the disease has become established in Portugal and is also recorded in France and Italy.
