This photo was taken the night of the first mowing of the recently seeded greens. The picture was taken to show what is suspected to be the bacterial wilt still active on the greens. There are areas like this on several greens. We had the tedious seeding process, but we DID NOT do anything to take care of or kill the bacteria in the soil. Hopefully the greens grow in and survive until the tournament next year.
My roommate Chris, he was really excited to be mowing the greens again at night. We stopped mowing them for about 2 weeks while they were growing in. This was the first cut on the 7th green. 

You can see the turf elongating in this photo, this was the very early stages of the problem
Here is one of the test plots on the chipping greenWhat the bacteria does: The bacteria lives inside the plant. It is thought to enter the plant when the blade is cut with a mower. When inspected under a microscope, the bacteria streams out of the xylem with like a "fire hose". The bacteria causes the plant to elongate. We would then mow the elongated plant causing the plant to be scalped. The scalped turf would be put under increased stress causing root reserves to be spent to aid turf recovery. Currently we have very short roots. There are areas on the edges of the greens where the mower has caused severe scalping. In these areas turf has been lost and the areas are filling in with algae and the bermuda grass is intruding. I have read on the internet, the problem will persist until day temperatures return to mid 70's.
"Rod Shaped" bacteria fill the veins in the plant
"Rod Shaped" bacteria exiting the plant
The plant is etiolated- thinning and elongating
You can see how the turf is elongated in this photo
Bermuda intrusion on the edge of the green
You can see how the turf is deteriorating here in the clean-up pass on the green
The best solution to the problem would be to rebuild the greens. The soil needs to be replaced, becasue we think it is a soil-bourne problem-simply re-sodding the areas would not help. I think we will try to continue to overseed the greens to get more bentgrass to grow. I would like to see the greens next spring to see what they do to get them in shape for the tournament.
