Remarks. Pratylenchus penetrans was described from greenhouse soil around roots of cotton and potato in Rhinebeck, New York ( Cobb 1917). It has been reported from 25 countries in Europe, 16 in Asia, 11 in Africa, 3 in North America, 3 in Central America and Caribbean, 3 in South America, and 3 in Oceania (CABI, 2003; Deimi et al. 2008). In the USA, it occurs in 38 mainland states and Hawaii (CABI 2003; Wang & Hooks 2009). Simard et al. (2008) reported that P. penetrans was uncommon in golf courses in Ontario and Québec, Canada. Here, P. penetrans was found in 36 samples taken in 23 counties in NC and SC, in three turf management zones (green, fairway and tee) and two grass species (bermudagrass and creeping bentgrass) in both states. The morphology and morphometrics of the identified population did not differ from previously described populations ( Corbett 1973). This is the first record of P. penetrans from turfgrasses in NC and SC.
