| Abstract/Contents: | "In sports turf management the turfgrass pathogen, Gaeumannomyces graminis var avenae, is primarily a problem on recently constructed sand based Bentgrass (Agrostis spp. L.) greens resulting in Take-all disease. The increasing legal restrictions on fungicide usage has prompted research into alternative methods of managing this disease. Trinexapac-ethyl (TE) [4-(cyclopropyl-a-hyroxy-methylene)-3,5-dioxo-cyclohexane- carboxylic acid ethyl ester] is a growth regulator that inhibits plant gibberellin production late in its synthesis and it is also thought to restrict the incidence of Dollar Spot (Scolrotinia homoeocarpa). An investigation was undertaken to determine if TE had any effect on Take-all disease incidence on newly seeded Creeping Bentgrass (Agrostis palustris Huds.) plots. TE was applied to the Bentgrass sward at a rate of 240 gha-1 three weeks prior to inoculation with G. graminis var. avenae. The weekly dry weights of clippings were recorded. At the end of the trial, the Bentgrass roots were visually assessed for infection, dry root and shoot weights were recorded and the roots were analyzed for manganese concentrations. A Petri-dish agar bioassy was also undertaken to assess if TE has any fungistatic properties towards G. graminis var. avenae when TE was applied at different rates to the agar. The results of the glasshouse trial were inconclusive, due to a failure to inoculate the turfgrass with G. graminis var. avenae. This could be due to the presence of a G. graminis var. avenae antagonistic fungus, Phialophora graminicola, on the plant root system. The bioassay indicated that TE exhibited fungistatic activity towards G. graminis var avenae." |
