Subanguina on poa roots
View Larger
Photo by Bjarni Hannesson, Ness Golf Club, Iceland. Closeup of Subanguina radicicola on Poa annua roots. Note the galling, irregular shaped roots. The most severe damage occurrs on the edge of the clubhouse putting green in the walk on/off area. No nematicides, Mr. Hannesson feels the poa stress provides an opportunity to overseed with nematode tolerant bentgrasses.
