UNUSUAL RYEGRASS??

Unusual Ryegrass?

Dr. Dave Minner, Iowa State University

We have been noticing some unusual areal shoots on what looks to be perennial ryegrass and we would like to hear from you if you have noticed anything like this at your facility. The pictures are from a football field in central Iowa.  The field is a mixture of Kentucky bluegrass and perennial ryegrass that has been infiltrated with some patches of K-31 type tall fescue.  Over the last three years it has been seeded with a mixture of Kentucky bluegrass and perennial ryegrass.  The ryegrass component was made up of GLS (Grey Leaf Spot) type ryegrass and Tetraploid Turf-Type ryegrass.  Our intent is to simply determine if others have observed this type of growth and if you consider it to be a positive or negative type of turf performance.

Please contact either myself or Andrew Hoiberg if you have seen anything like this:
