| Abstract/Contents: | "The prevalence of lance nematodes, Hopolaimus galeatus, is increasing on cool-season golf course putting greens in Virginia, with limited control options available. Plant growth regulators (PGRs) are often used in putting green management and golf course superintendents have suggested that damage associated with plant-parasitic nematodes may be related. To date, there is no information available in the literature to validate or refute this relationship. The objectives of this study were to determine whether the addition of fluopyram to PGR applications impact creeping bentgrass quality and how fluopyram combined with PGRs impact lance nematode populations. A 5x2 factorial study was conducted at five locations across Virginia for 16 weeks to assess the impact of fluopyram, PGRs, and their interaction on putting green quality and nematode populations. Five PGR treatments consisted of trinexapac-ethyl (47.7 g ai/ha, 14 days), prohexadione calcium (154 g ai/ha, 14 days), flurprimidol (280 g ai/ha, 28 days), and paclobutrazol (175g ai/ha, 42 days) and a non-treated control. Fluopyram was applied every 28 days at 373 g ai/ha and compared against a non-treated control. Visual assessments were collected every 14 days with root samplings for nematode populations and root length at initiation, midseason, and final ratings. Differences in phytotoxicity for all treatments were significant (p<0.05) at four of five locations, but were well below the acceptable damage threshold of 30%. Visual damage associated with lance thinning were not different at any location. Differences in creeping bentgrass quality were significant at one location for PGRs (p=0.0066) and fluopyram (p=0.0003), with relative root length reduced by fluopyram at one location. Relative change in lance populations were not different at any location. To date, there is little evidence to suggest that applications of fluopyram with PGRs has an impact on creeping bentgrass quality or lance nematode populations, though further exploration is ongoing." |
