With a majority of the snow still on the ground, days like today are spent on different tasks both inside and outside. Its a great time to plan for the coming season, specifically by laying out our chemical application schedules for greens, tees and fairways. By proper planning, we are sure we maximize the efficiency of different products available to us and also make sure we aren't applying too much of a specific product. All pesticides are regulated by the EPA and maximum use rates in a given year. Furthermore, using the same product without rotating different modes of action, can risk resistance issues where a particular fungus becomes resistant to a fungicide. This can be dangerous because it eliminates the tools we have in our bag. One example at Highlands CC is the fungicide, Cleary's 3336 (Thiophanate Methyl). While it should give 21 days control of dollar spot, we get 4 days control. Of course, we don't use it any longer and we have plenty of other options at our disposal. However, there are many diseases that don't afford that luxury.
