GRAY LEAF SPOT DID SHOW UP IN CENTRAL IOWA

On August 31, I posted a blog titled "Watch Out For Gray Leaf Spot".

It did show up.  Here is a post from Cory Johnson, Superintendent of Cedar Pointe Golf Course in Boone, Ia.  This is Gray Leaf spot.  It showed up on September 8.  These pictures are from Sept. 16.  This is classic Gray Leaf Spot on perennial ryegrass fairways.  They will need to reseed with ryegrass as soon as possible.

If anyone else has experienced this, send me some pictures.  I suspect that there is more out there.


The first two pictures are fairway shots.  It is the rye that died and there is some live Kentucky bluegrass.







Picture 3 shows a close up of live bluegrass in dead rye.


Picture 4 shows leaf symptoms on the rye.
