Dollar spot disease on fairway

The wet spring has many benefits for the turf at Victoria Park. The rough has never been this lush and thick this time of year. We have hardly had to water the golf course. The water table is high and the course looks great. The downfall of all the rain is we can hardly keep up to keeping the rough mowed and as a result, some golfers complain about how hard it is to play and find their balls. The other problem with so much wet weather and especially the high humidity is the presence of turf diseases. Turf diseases which are also referred to as fungus, pathogens, mould etc. and are the most persistent (and expensive) pest problem on golf courses in southern Ontario. The main reason is the type of turf grass used on most golf courses. Creeping Bentgrass and Annual Bluegrass is much more prone to turf diseases than Kentucky Bluegrass which is primarily found on home lawns. There are also many different types of Turf grass diseases some prefer cool weather and some prefer hot weather. Some diseases will only occur once if the weather conditions are just right and some are more persistent and last all season long. Some disease are more of a nuisance and some can be devastating if left untreated. Some diseases can go untreated  especially if the weather conditions will that caused the outbreak are no longer present. Some diseases do have to be treated with a fungicide. This is especially true for dollar spot. Dollar spot shown in the picture is the most persistent disease at Victoria Park East. The Creeping bentgrass and annual bluegrass (poa) greens, tees and fairways are very susceptible. Golfers may have already noticed the spots about the size of a silver dollar. If left untreated the spots will spread and eventually kill the turf. Lets hope for some less humid weather.
Until next time…
