| Abstract/Contents: | "Brown patch, caused by Rhizoctonia solani, is a foliar disease of creeping bentgrass that causes significant damage during periods of hot, humid weather throughout the Midwest. Turf managers typically utilize an integrated approach to minimize disease damage. Practices such as adjusting fertility, limiting leaf wetness, selecting less susceptible cultivars, and applying fungicides preventatively have been shown to influence brown patch severity (Smiley et al., 2005). Fungicides used for controlling brown patch are applied at 7 to 28-day intervals per label directions. Once fungicide is delivered to the turf canopy, numerous factors will influence how long it will persist. Frequent mowing, microbial breakdown, photodegradation, plant metabolism, removal from irrigation or rain, and volatilization can limit the amount of fungicide present (Latin, 2006). Depletion of effective fungicide residues during the latter half of the application interval predisposes turf to brown patch outbreaks of disease-favorable weather persists. The objective of this research was to describe the temporal nature of fungicide residues for controlling brown patch on creeping bentgrass maintained under fairway conditions. Results from the bioassay demonstrate differences in residual efficacy among the selected fungicides." |
