First Report of the Yellow Nutsedge Cyst Nematode, Heterodera cyperi, in Georgia, U.S.A.

ABSTRACT: Soil samples collected during a survey for plant-parasitic nematodes in Tift County GA in summer 2017 were submitted for routine diagnosis of nematodes to the Extension Nematology Lab at the Department of Plant Pathology, University of Georgia, Athens, Georgia. Cyst nematodes recovered by centrifugal flotation technique were discovered in the samples from two research sites in a field with a history of tobacco and vegetable production. Cyst nematodes from tobacco (10 cysts/100 cm 3 of soil) and vegetable (2 cysts/100 cm 3 of soil) sites had similar morphological features. Morphology and morphometric measurements of the cysts and J2 ( Fig. 1A-C ) were in agreement with those of Heterodera cyperi ( Golden et al., 1962 ; Romero and López-Llorca, 1996 ). Measurements of J2 ( n = 12) included t
