European Larch Canker, Lachnellula willkommii

European larch canker, caused by the fungus Lachnellula willkommii, is a serious disease in many parts of Europe. It was first reported in North America in 1927 in Massachusetts, and is now established in New Brunswick, Prince Edward Island, and Nova Scotia, Canada, and Maine, U.S. where it kills mature and immature species of trees in the genus Larix (larch, tamarack, hackmatack). A federal domestic quarantine has been established to prevent its spread (Maine Title 12, MRSA 1988, Chapter 803, §8305 and USDA-APHIS PPQ regulation 7 CFR 301.91).

The severe impact of the canker on larch in parts of Europe and its potential impact on North American species has prompted Environment Canada, the USDA Forest Service, and Maine Forest Service to issue public-information flyers urging extreme caution in transporting cuttings and seedlings (USDA Forest Service, 1991).
