Last mowing at normal fairway height of cut/Large patch on zoysia application

Monday was the last day we mowed fairways at the normal summer cutting height.  The growth has slowed with the shorter light period and cooler nights.  We raise the height to allow the turf to begin to store energy for winter and to help protect it from the cold temperatures we will experience.

We will probably mow the turf at the new height for a couple of more weeks and will then allow it to go into dormancy a little taller.  Best year for zoysia that I have seen in a long time.

Assistant Mike spent the first two days this week applying our Large Patch on Zoysia treatment.  This application is made to all tee, fairway, and green surround areas that contain zoysia to help reduce the negative of effects of this disease next spring which is the time of year that our zoysia is more susceptible to the disease.   If we waited to apply the material next spring at a curative rate, the disease would be much more difficult to control and the disease do more damage to our turf.  The fall preventative application does not  always prevent the disease from occurring but it does slow its overall affect.

Here is the link to last fall and spring postings regarding large patch if you are interested in further reading.
Its interesting in the activity of the disease from one year to the next.  Last year, we had activity as early as August 31st.  This season, I've seen just a couple of minor spots on September 25th.

You can see the spray tracks in the dew and the marker foam that is used to help the operator keep the spray in proper alignment.
