Northern Region, James, Robert L. Needlecast caused by Meria laricis caused serious losses of 2-0 bareroot western larch during 1983 at the USDA Forest Service Nursery, Coeur d'Alene, Idaho. Cool, wet weather throughout the spring and summer of 1983 was ideal for disease buildup and spread. Control attempts with fungicides were largely unsuccessful because of the conducive weather conditions and high inoculum levels. The disease was also found on containerized larch, although serious damage was not evident. The 1984 bareroot crop had high levels of infection in the spring, but consistent fungicide treatments and warm, dry summer weather resulted in no detectable disease by the fall.
