| Abstract/Contents: | "Two triazole fungicides (triadimefon and propiconazole) were compared with pentachloronitrobenzene (PCNB) for control of Typhula blight and pink snow mold of creeping bentgrass. In an experiment repeated in consecutive years, propiconazole applied at rates of 3.0 and 6.0 or 12.0 kg a.i./ha, or triadimefon applied at 12 kg a.i./ha, suppressed the development of Typhula blight and pink snow mold to levels that were not signficantly different from disease intensity in plots treated with PCNB at 30.0 kg a.i./ha. Triadimefon, applied at 1.5, 3.0 or 6.0 kg/ha suppressed Typhula blight, but not pink snow mold, to levels equivalent to those provided by PCNB. Eight months after application, significant residual suppression of dollarspot disease was observed in plots treated with 3, 6, or 12 kg a.i./ha of triadimefon or 12 kg a.i./ha of propiconazole in 1985 or with 12 kg a.i./ha of either fungicide in 1986. A consistent, but nonsignificant (P=0.05), increase in the intensity of dollarspot was observed in 1986 and 1987, 8 mo after application of PCNB. |
