Scientific name: Pythium aphanidermatum

There have been numerous reports of a cool weather dieback problem on golf courses in regions near the Great Lakes. Turf managers report that this dieback tends to occur in periods of cool wet weather in spring and fall, and shows as a scattered blighting or yellowing of turf in small patchy areas . Some of these incidents have been associated with Pythium species that are also associated with root rot of turfgrass. This phenomenon is commonly known as Pythium Root Disfunction. Debate continues as to the exact causes of this disfunction. Currently there are no registered treatments in Ontario for control of Pythium Root Disfunction.
