(By Jared Hoyle, KSU Turfgrass Research and Extension)
Someone told me and I am not sure if it is correct or not, “that grey leaf spot will infect crabgrass before it hits our desirable turfgrass species”. The other day I saw some grey leaf spot crabgrass in a ryegrass lawn and got me thinking that this is about the time grey leaf spot starts to kick in around here. I went back through the blogs and back in 2015 (Actually August 25, 2015) I posted about grey leaf spot.
I wanted to pass along the blog again for everyone that may have had grey leaf spot in the past.
