Abstract

First report of brown ring patch caused by Waitea circinata var. circinata on Poa annua and Agrostis stolonifera in New Jersey.

Abstract

In early April to mid-June of 2009, circular to irregularly shaped yellow rings resembling symptoms of Waitea circinata var. circinata [Waitea circinata] were observed on an annual bluegrass putting green in North Brunswick, New Jersey. During the same period, similar disease symptoms were observed on creeping bentgrass (Agrostis stolonifera) from a golf course in Bedminster Township, NJ. ITS sequence data, morphological characters of the isolates, and pathogenicity tests confirmed the identity of W. circinata var. circinata. This is thought to be the first record of W. circinata var. circinata infecting turfgrass in New Jersey.
