Abstract
Gremmeniella abietina was able to survive in vitro for four weeks at average temperatures less than 30° C. At higher temperatures, survival time was inversely proportional to temperature. The fungus survived for 23–28 months inside asymptomatic trees. Freezing, or freezing and thawing, of inoculated trees, may have promoted symptom development.
