Dandelions in summer patch areas from last year

May 24, 2016

On July 6, 2015, I posted a blog about summer patch, caused by (Magnaporthe poae), on the turfgrass research area.  It was a major outbreak of this disease.  In late May, a few days ago, I was looking at the area.  The disease is not active now, but the interesting thing about the area is how dandelion seed landed in the dead part of the rings and germinated in the fall and spring. 

 

The first two pictures are from the post on July 6 of last year when the summer patch was active.  The last 4 are from May 20, 2016 showing the dandelions.  The dandelions had been treated with a broadleaf herbicide a week earlier.
