This is an area on our #4 green south. Over the last 3 seasons we have seen the same symptoms in the same area each year. The area gets wilted very easily and the roots are dysfunctional. We thought it was take all patch. This is on a Penn A-4 green. This spring we treated the green with 2 applications of Heritage. It is not as bad as in prior years but it was showing up again in the hot weather.
 

We sent a sample off and it did test back as take all patch. Recommendation from the lab was to solid tine aerify, keep the nitrogen level up and to do multiple fungicide applications in the late fall and early spring. Also to incorporate Manganese sulfate in our spray next spring. It does look better this week.

Here are a couple of pictures from Eric Van Ginkel, who works for the Iowa Cubs.  He also works on several other sports fields in the Des Moines area.

This was a field that had highly compacted soil following construction.  They sodded it last fall with Kentucky bluegrass, but the sod had shallow roots and grew slowly because of the compaction.   This spring, they deep-tined the area with solid tines.  The area improved.  They recently used hollow tines on the deep-tine unit to pull cores.  These pictures show the rooting into the holes from the solid tines in the spring in cores that were removed this fall.

This is something that I have observed as well on area that have been deep-tined with solid tines.  It is amazing how much root growth can occur in these aerification holes.  We will need to do a follow up in the spring and see how much rooting there is into the holes left by the hollow tines.
