Territory Weather Conditions – Wet conditions halt turf mowing and preventative fungicide application schedules
The very wet and cool weather pattern continues for the majority of the territory. Friday-Sunday (May 20-22) has been pretty much without a rain event and we have had warmer temps. Unfortunately, the report for Monday-Thursday of the week ahead is calling for 30-50% chance of rain across the territory. This means there will be some areas that will not miss the rainfall.
If temperatures continue to be warm, we should experience some above average levels of dollar spot. It will be especially notable because many golf course supers have not been able to apply any early preventive fungicide applications.
Golf course superintendents have had difficulty mowing fairways on a consistent basis. Mowing roughs has been even more of a challenge. Golf courses that normally fertilize and apply weed control in roughs are eliminating this as an option. In some cases, they are applying some weed control to these areas when it is dry enough to do so. On Friday, we had 100% relative daytime humidity.
Disease Conditions – Leaf spot, pink snow mold, brown ring patch
Turf diseases thus far have been leaf spot/melting out stage, lots of pink snow mold & some brown ring patch (pictured). Golf course PGR applications are behind schedule, poa annua seed heads are evident pretty much at every golf course.
Next week - Vacation!
