Turfgrass is commonly grown throughout the United States for a wide range of uses, including golf courses, pastures, homeowner lawns, sod production, and institutional facilities (Breuniger et al., 2013). Economically, turfgrass has been estimated to have a total revenue of over $62 billion dollars, and geographically covers over 160,000 km2 of land (Haydu et al., 2005; Milesi et al., 2005). In the southeastern US, bermudagrass (Cynodon spp.) is the most commonly grown perennial warm-season

farm located in South Georgia. While processing these samples, 112 stubby-root nematodes per 100 cm3 of soil were found to be associated with this turfgrass, which is currently grown in many sport fields and golf courses in Georgia and Florida. This prompted us to first study the pathogenicity of Nanidorus spp. to seashore paspalum turfgrass and second to determine the species identity using both molecular and morphological techniques. Accurate species identification of the nematodes can be helpful

Turfgrasses are among the most widely used ornamental plants in the world, serving important functions in soil stabilization and providing safe surfaces for recreational activities (Zeng et al., 2012a). Moreover, the quality of the turf in the sports areas, mainly football fields and golf courses, is crucial and any imperfection can have a huge impact (Oliveira et al., 2018). Of all turfgrass pests, nematodes are probably the least understood and most often overlooked. Due to this, nematode

Turfgrass (Cynodon spp.) is an important horticultural crop in the Southeastern United States. Golf courses, athletic fields, and lawns utilize turfgrass as a playing surface and as ground cover. Turfgrass cultivation, sales, and maintenance is a billion-dollar industry in Florida (Haydu et al., 2006). Plant-parasitic nematodes are an important pathogen of turfgrass. Nematode feeding can lead to stunted roots and even death of the plant (Crow, 2008). As an aesthetic crop, turfgrass managers

In 2016, “Tifdwarf” hybrid bermudagrass (Cynodon dactylon (L) Pers. × C. transvaalensis Burtt-Davy) grown on a golf green built to the United States Golf Association recommendations in Barbados started to show irregular significant chlorotic patches followed by gradual thinning and decline of turfgrass. Additionally, turfgrass roots sampled from the symptomatic patches appeared to be abbreviated compared to non-symptomatic areas of the greens. A survey was conducted in May 2016 to determine the

. Twenty soil cores and their respective grass cover were collected and combined to form composite samples; the loose sandy soil was kept separate from the plug-like thick root masses of turfgrass.
Turfgrass roots were rinsed in water and upon observation with a stereomicroscope, small galls were detected, from which Meloidogyne females were excised (Fig. 1A). The perineal patterns from five adult females were prepared in 45% lactic acid and mounted in glycerin (Hartman and Sasser, 1985). Shape was

Material and methods
Host status of common weeds to Meloidogyne spp.
We evaluated the host status of yellow and purple nutsedge and coffee senna to Meloidogyne arenaria, M. enterolobii, M. floridensis, M. hapla, M. incognita, and M. javanica. ‘AgriSet 334’ tomato (Solanum lycopersicum) was included as a susceptible control. This experiment was

These same two species are reported as the predominate Meloidogyne spp. associated with golf course bermudagrass in North and South Carolina (Zeng et al., 2012; Ye et al., 2015), Texas (Faske and Starr, 2009), and California and Hawaii (McClure et al., 2012).
