| Abstract/Contents: | "Dollar spot is a common disease of both warm- and cool-season amenity turfgrasses caused by Clarireedia species. Previous field studies have shown dollar spot suppression with 48.8 kg ha-1 ferrous sulfate heptahydrate. In vitro research suggests that 1001,000 mg L-1 ferrous sulfate concentrations suspended in agar will directly inhibit Clarireedia mycelial growth. The impact of ferrous sulfate concentration on dollar spot development in situ is not clearly defined. Our research explored five field rates and five concentrations of ferrous sulfate against dollar spot development in situ and Clarireedia growth in-vitro, respectively. Field-applied rates included 0, 4.88, 24.4, 48.8, and 97.6 kg ha-1 ferrous sulfate. Our data indicate a nonlinear relationship between ferrous sulfate rate and dollar spot development, with 26.4 kg ha-1 required for 50% dollar spot suppression and only a 10% increase in suppression with previously reported rates of 48.8 kg ha-1. Ferrous sulfate suppressed dollar spot on both golf course fairways and putting greens. Radial mycelial growth of four isolates were modeled using ferrous sulfate-amended agar at concentrations of 0, 200, 400, 600, and 800 mg kg-1. Effective concentration required to suppress Clarireedia growth by 50% ranged from 511 to 687 mg L-1 and varied by isolate, though the relationships for all had a negative linear relationship of mycelial growth to concentration. Radial growth of the two isolates collected from warm-season grasses grew faster than two isolates collected from cool-season grasses." |
