Ever increasing regulations are seeing the elimination and restriction of popular turf fungicides that have aided superintendents in maintaining golf courses in our harsh conditions. The most recent to be added to this list is quintozene, which, for the last four years we have used to treat our fairways and have had great success at an affordable cost (see above picture). It was announced in the fall of 2010 that as of December 31st, 2010, quintozene would no longer be registered for use in Canada so we had little time to experiment with other fungicides to find a replacement. We have started experimenting with other options, all while trying to do it at an affordable cost. In 2010 we treated fairways 4, 8, 12, 14, 15, and 16 with different fungicides that were similar in cost but as you can see by the picture below of the 8th fairway there was little success. We will continue to experiment and research new products in order to find a product or combination of products that will be most beneficial in the prevention of snowmold on fairways.
