| Abstract/Contents: | Presents a study conducted to "evaluate the importance of SV [spray volume] as well as the presence or absence of dew on the ability of fungicides to control DS [dollar spot]." Details methods and materials used in the study, stating that "field studies were conducted from 2002 to 2004 at the University of Maryland in creeping bentgrass maintained as fairway turf. Treatments were applied with a CO2 [carbon dioxide] pressurized sprayer (35 psi [pounds per square inch] equipped with either a 8004 (1.1 gal/1,000 ft2 [gallons/square feet], low SV) or 8010 (2.5 gal/1,000 ft2, high SV) flat fan nozzle." Reports that in 2002 "eight days after the initial fungicide application (28 June), all treatments significantly reduced DS levels when compared to the untreated control...In 2003, dollar spot peaked on 16 August...On 16 August, the SV contrast data showed that chlorothalonil applied in the low SV...gave better DS control when compared to plots treated with high SV...On 9 of 18 rating dates in 2004, chlorothalonil applied in the low SV provided better DS control when compared to treatments applied in the high SV." Concludes that "appling fungicides in higher dilution may be more beneficial when targeting root pathogens or in curative programs for foliar diseases." |
