“…The turfgrass-associated genera Helicotylenchus, Paratrichodorus, Hoplolaimus, Meloidogyne, Hemicriconemoides, and Mesocriconema showed high infestation and frequency in this study, and most of these genera had numbers in soil samples above the damage threshold. For example, Helicotylenchus was widely distributed with a high infestation rate in NC and SC, and the number of Helicotylenchus in a soil sample from Shanqin Bay golf course significantly exceeded the damage threshold [ 13 ]. Meloidogyne has been reported to cause great economic losses and severely damage the root system of turfgrass [ 43 , 44 ], and was found to exceed the damage threshold in soil samples from Shenzhen Sand River golf course [ 13 ].…”

In this study, we found that more genera appeared to cause damage on turfgrass in EC and SC compared to NC, and the number of nematode genera (abundance > 1) did not exceed the damage threshold in NC.…”

“…Most nematodes only cause visible damage when the population is very high and the turfgrass is stressed. PPNs vary in their virulence, and different PPNs have different damage thresholds [ 13 ]. Nevertheless, nematodes consistently cause severe damage, and the most damaging PPNs on turfgrasses may vary across different regions and countries [ 6 , 13 ].…”

Nevertheless, nematodes consistently cause severe damage, and the most damaging PPNs on turfgrasses may vary across different regions and countries [ 6 , 13 ]. The sting nematode, Belonolaimus longicaudatus , is considered the most damaging PPN on bermudagrass in the southeast United States, while the root-knot nematodes ( Meloidogyne spp.)…”

We sampled 127 turfgrass soil samples from 33 golf courses in NC, EC, and SC for plant-parasitic nematodes (PPNs). PPNs were extracted from soil samples using the shallow dish method and were identified at the genus or species levels with a combination of morphological and molecular methods. The results revealed 41 species of nematode belonging to 20 genera and 10 families. Nine genera are new records of PPNs associated with turfgrass in China. The PPNs show strong geographical distributions. Of the 20 genera, Helicotylenchus, Paratrichodorus, Hoplolaimus, Meloidogyne, Hemicriconemoides, and Mesocriconema showed higher infestation and frequency, and most of these genera had numbers in soil samples above established damage thresholds. Four golf courses had soil samples with PPNs > 30%, indicating the potential for nematode damage. The biodiversity indices H’, SR, J’, λ, and H2 showed significant differences among different regions and turfgrass species; H’, SR, J’, and H2 were significantly higher in EC than in NC and SC, while λ was lowest in EC. Creeping bentgrass had the highest H’, SR, J’, and H2 and the lowest λ in comparison with seashore paspalum and hybrid bermudagrass. These findings provide baseline information on the occurrence of turfgrass-associated PPNs in China, and have important implications for the effective management of PPNs causing damage on turfgrass.
