First report of Trichodorus obtusus on turfgrass in North Carolina, U.S.A.

Abstract

In May 2014, a total of 11 sandy soil samples were collected at a depth of approximately 5-15 cm from a golf course community in Wilmington, North Carolina, USA, composed of bermuda grass (Cynodon dactylon) from the fairway, St. Augustine grass (Stenotaphrum secundatum) from the lawn and Zoysia grass (Zoysia japonica) from the tee, all of which showed spotted yellowing and necrosis. The causal pest was identified as Trichodorus obtusus based on morphological and molecular analyses. This is thought to be the first report of T. obtusus on turfgrasses in North Carolina, USA.
