As of yesterday several cases of Brown Ring Patch / WaiteaPatch (Waitea circinata var circinata) on Poa annua have been reported. The disease is often active during the transition period of winter/spring to hot early summer like weather conditions, i.e. like we are having in Ohio this week. Even though the disease maybe wide spread on greens and surrounds (we have seen on tees) and the symptoms can be very noticeable, in most cases serious damage does not occur.

Questions are coming in about the timing of the first application of fungicides for Summer Patch. Usually the recommendations are for the first application to go down when:
Soil temperatures are 65°
At a 3 inch depth
For 3 consecutive days
Due to the unusual warm weather and the likelihood that a cool down will occur, it may be wise to wait a bit longer for the first application. Also some researchers are recommending waiting until soil temperatures are closer 70-75° F before making the first application.

The following are situations that may be seen in lawns at this time of year. Some of these may require some care and others will recover with new growth as spring conditions develop and the turf plants grow.
