"Snow molds are major diseases on golf courses in Canada and the Northern U.S. Regulations in some communities have superintendents seeking alternative means to to traditional fungicides to control snow molds. Seeds and tissues of various cruciferous species (such as mustards and canola) have been shown to inhibit snow mold fungi in lab and field tests. Oilseed radish was found to show greatest fungicidal activity in our previous research. Current research is examining the type of oilseed radish tissue and rate for effective snow mold control along with field testing of commercially available product containing tissue of oriental mustard for control of snow molds and other turf diseases. The results of this research may identify alternative means of snow mold control that superintendents can use in situations where traditional fungicides are not allowed. This research was funded by the Canadian Turfgrass Research Foundation."  Other details on this research can be found in:
