Abstract
The distribution, frequency, and population levels over time of plant-parasitic nematodes were surveyed on 114 greens from 38 different golf courses throughout southern New England. Sampling took place in the spring, summer, and fall of 2003 and 2004. The predominant genera of phytoparasitic nematodes recovered from soil samples were Tylenchorhynchus, Helicotylenchus, Criconemella, Hoplolaimus, and Heterodera. Tylenchorhynchus and Helicotylenchus spp. were the most common, found in all 38 golf courses sampled. Population levels were significantly higher (α = 0.05) in 2004 than in 2003 for Criconemella, Tylenchorhynchus, and Heterodera juveniles. There was a significant effect of season on population levels of Criconemella, Tylenchorhynchus, and Heterodera juveniles in the 2003 sampling year, and on Helicotylenchus, Tylenchorhynchus, and Heterodera juveniles in 2004. Population levels were highest in the fall for all genera except for Tylenchorhynchus, which were highest in the summer for both years. The results of this study suggest that parasitic nematodes are present in relatively high numbers in golf course turf soils in southern New England, and that there are variations in the dynamics of population levels among the different genera found in the area. © 2006 The American Phytopathological Society.
