Synchytrium endobioticum, the causal agent of potato wart disease, is soilborne. It is indigenous to home gardens throughout the island of Newfoundland. Scrapings from windows of a shed proximate to heavily infested soil yielded resting spores. To make a qualitative statement about wind dispersal, simple impaction devices were examined for periods between June and October. Spore recovery at the sample site during the sampling period was estimated at >1,000. The role of wind in dispersal, and its potential in the contamination of vehicles that exit the province, is discussed.
