| Abstract/Contents: | "The golf course industry in North Carolina is in the midst of a major transition as many courses throughout the eastern and central regions of the state are switching putting green turfgrass species from creeping bentgrass (Agrostis stolonifera) to bermudagrass (Cynodon transvaalensis). This change has multiple implications for management, including nematode disease control. Many courses throughout the state already have nematode parasitism issues, but there is very little research on nematode feeding tolerance of putting green turfgrass cultivars. The purpose of this project was to determine nematode feeding tolerance of bermudagrass and creeping bentgrass cultivars. Five cultivars of both bermudagrass and creeping bentgrass were chosen, with newer cultivars being emphasized. The study was performed in a growth chamber and greenhouse using small conetainers of turfgrass. Sting (Belonolaimus longicaudatus) and root-knot (Meloidogyne graminis) nematodes were inoculated either separately or together. Overall turf quality and clipping weights were recorded weekly, and root weight, length and nematode counts were sampled at 6 weeks at the termination of the study. Results showed that newer cultivars of creeping bentgrass were more tolerant of nematode feeding damage than the older cultivars. New cultivars Pure Select and Crystal Bluelinks all showed turf quality equal to or better than the uninoculated control. Penn A1 and Pure Distinction saw a slight decrease in overall quality, with the most significant decrease being from sting nematode feeding alone. Penncross performed the worst, with nematode feeding reducing turf quality below the threshold for acceptable putting green quality. Bermudagrass cultivars are currently undergoing screening. Overall, this indicates that while the newer cultivars may not be specifically screened for nematode feeding tolerance, the improved plant characteristics help these cultivars to better tolerate nematode feeding damage to roots." |
