What is that stuff?

This is Dollar Spot (turf fungus) that is been growing rapidly in rough areas.  This is the tee bank along the 16th tee box.
 
This is what Dollar Spot looks like on a fairway.  We have seen some severe disease pressure and fungicide efficacy has been shortened.
This is a picture of Brown Patch.  A number of these diseases we have seen very little of in the past few years.  This is primarily because of the quantity of pressure and the severity shortening our spraying windows/schedule.
Why are covering that green with soil?
That is a green that has been topdressed with a layer of sand and is in the process of being cored.  After the green is cored we drag the sand and cores to fill the holes in the greens back up.

These are pictures of #7 and #12 right after we received that 1.5" rainfall.

Enough with the Heat

   We have been able to complete greens aerification in spite of the 1.5" of rain we received Sunday night. We were delayed but finished up the remaining greens Monday. The 4th and 6th green were very saturated and have not cleaned up well.
   We have completed some of the tees but feel it is best if we wait to complete those until after this bad spell of weather ends. We are in the midst of a bad weather week. Temperatures are staying between 85-90 degrees, the humidity if very high and we have continued to receive additional rainfall all week.  So far the golf course is doing alright and we do have preventative fungicide applications down but with disease pressure this high the fungicides efficacy will be reduced. We have been scouting for signs of break through and have made spot applications to help us through this intense pressure.  The good news is there is a break in the weather pattern coming Sunday. 
  Unfortunately golf is played on a playing surface that is constantly changing and the weather plays a key role in that. We are going to do our best to keep it in the most playable condition we can.  That is why we have closed the course for cart use a couple of times this week.  We did not want to stress the turf out more and invite pathogens to infect the turf.  We are hopeful green speeds will return to normal next week as the greens dry out and begin to heal.
