| Abstract/Contents: | Presents a study to "determine the effect of pre-plant and post-plant treatments on the establishment and spread of take-all patch of creeping bentgrass in a sand-based root zone prepared according to USGA specifications. Specific objectives include assessing the development of take-all patch on bentgrass planted in USGA root zones adjusted to three different pH levels", and "comparing root zone acidification treatments and fungicide applications for take-all control." Results for 1999 include that "reduced pathogen activity due to elevated root zone mix temperatures resulted in a remission of symptoms from mid-July through late October...Results for the four evaluation dates were consistent in that disease levels were reduced with fungicide treatments and ammonium sulfate application. Also, there were declining levels of disease in plots where the upper inch of root zone mix was acidified with aluminum sulfate prior to inoculation in spring 1998...Plots that were treated with fungicide sustained significantly less disease development than unsprayed plots. Where no fungicide was used, the ammonium sulfate treatment resulted in significantly less take-all patch development than where the balanced fertilizer was used...The evaluations recorded in May revealed similar results...Evaluations recorded in June revealed a lessening of symptom expression for all treatments...The decline of symptom expression continued into July." |
