Yesterday we applied two fungicides to the greens. With the soil temperatures on the rise, we have to start getting preventative for the summer diseases. We closely monitor the soil temperature and when the 4" soil temperature reaches the 55-65 degree range for over a five day period it is time to start our preventative program. The first disease we targeted is Fairy Ring. This appears in the summer, but the fungicide is applied now. It is a two time application with the first app going out yesterday and the second app coming 21 days later.
The second disease we started targeting yesterday is Pythium Root Dysfunction. Pythium is one of the scariest diseases for bentgrass in the summer. It can completely kill a green in hours. All forms of Pythium are what we plan for most in our preventative fungicide plan. We started our rotation of chemicals yesterday and we will continue every two weeks until after our fall aerification.
