| Abstract/Contents: | Presents a study conducted to "determine and describe the causal organism of Pythium root dysfunction in North Carolina"; "evaluate the effects of temperature and soil types on disease development"; "develop effective chemical and cultural control measures for Pythium root dysfunction in North Carolina"; and "develop an accurate and rapid diagnostic tool for Pythium root dysfunction." States that "since 2002, many golf course superintendents have reported 'strange' patches appearing on their creeping bentgrass greens." States that "stand symptoms typically develop during periods of warm, dry weather as irregular patches ranging from six inches to several feet in diameter." States that "little is known about the effects of these Pythium [P. volutum and P. torulosum] species on mature turfgrass plants." Discusses pathogen biology and speculates "if the propagules of P. volutum spread mechanically by equipment or foot traffic." Discusses the results of a study involving "five P. volutum isolates and two P. torulosum isolates...The results demonstrate that P. volutum is a highly aggressive pathogen of mature creeping bentgrass plants." Discusses possible "fungicides for preventative control of Pythium root dysfunction...pyraclostrobin treatments (0.9 oz.) exhibited the lowest disease-severity rating compared to the untreated control." Concludes that "P. volutum is highly sensitive to pyraclostrobin, which explains its effectiveness in the field." |
