| Abstract/Contents: | "The turfgrass pathogen, Microdochium nivale, causes disease symptoms which require the most fungicide use on Nordic golf courses. As part of their Integrated Pest Management (IPM)1 strategies, greenkeepers are searching for (1) turfgrass species and varieties with a high degree of resistance to M. nivale, and (2) alternative lowrisk control agents that can replace or minimize the use of conventional fungicides against this pathogen. One product that may fulfil both criteria is Civitas OneTM, a mixture of food grade isoparaffins (Civitas mineral oil) and a strongly blue-green copper-containing pigment (HarmonizerTM; all produced by Suncor Energy, Mississauga, Canada). CivitasTM has no direct fungicidal properties, but there is evidence that that it may induce systemic resistance to M. nivale and other pathogens in creeping bentgrass (CB, Agrostis stolonifera L.)2. The activation of resistance genes is, however, a complex mode of action by which the ultimate effect on disease development may vary among cultivars within the same species. A Canadian pot experiment found that the disease suppression by CivitasTM + HarmonizerTM under the ambient CO2-concentration of 400 ppm varied from 27 to 54 % among six cultivars of CB, but the cultivar x treatment interaction was not statistically significant3. Thus, the objective of this research was to conduct a wider screening of CB cultivars commonly used on Nordic golf courses for their response to pre-treatment with Civitas OneTM before inoculation with M. nivale." |
