This disease is caused by the fungus Meria laricis. The pathogen infects western larch seedlings in nurseries in northwestern North America. Outbreaks of the disease have been reported in bareroot nurseries in Washington and Idaho. Larch needle cast appears to be especially damaging to 2+0 bareroot stock at the beginning of the second growing season.
