Abstract/Contents:"Scientists at Pennsylvania State University initiated research to determine if different products containing chlorothalonil, propiconazole, or iprodione provide different levels of control of dollar spot and brown patch diseases of bentgrass maintained as a golf course fairway. Their results include: With respect to dollar spot control, iprodione products generally showed better control than chlorothalonil and propiconazole products at the University Park location. However, at the Bellewood Golf Club site the three different active ingredients provided similar dollar spot control. Generally, chlorothalonil and iprodione products provided better brown patch control than propiconazole products. Chlorothalonil products included in this study (Daconil Ultrex, Echo Ultimate, and Chlorothalonil DF) typically performed similarly in both dollar spot trials and the brown patch trial. No differences among propiconazole-containing products (Banner MAXX, Propiconazole 14.3, ProPensity 1.3ME, and Spectator Ultra 1.3) were observed with respect to dollar spot control in either dollar spot trial. ProPensity 1.3 ME showed better brown patch efficacy compared with Spectator Ultra 1.3 on one of four rating dates in 2008, but was the only propoconazole treatment showing brown patch suppression in 2009. This was also reflected in AUDPC data (area under disease progression curve). Of the three iprodione products (Chipco 26 GT, Ipro 2SE, and Raven), Chipco 26 GT and Ipro 2SE provided the most consistent dollar spot control. Raven showed less dollar spot control when compared with Chipco 26 GT and Ipro 2SE on several rating dates and in AUDPC values in both years. However, at the University Park site, Raven provided equal or better dollar spot control when compared with propiconazole and chlorothalonil products on several rating dates."
