| Abstract/Contents: | "Seven treatments were evaluated on a 72-year-old sward of creeping bentgrass in southern Ontario during October 2000 to April 2001 for Fusarium patch and pink snow mould control. In Experiment A, Microdochium nivale inoculum was applied on 13 October 2000 to initiate Fusarium patch disease on plots that had very light levels of natural infection. Rovral Green 240F at 250 ml/100 m2 was then applied from 13 October until 27 november on schedules differing for the separate treatments. All fungicide plots were treated with Nutri-Q (containing 0-0-5 NPK plus 5% quintozene=PCNB=pentachloronitrobenzene) at 4.6 kg / 100 m2 on 15 December 2000. In early November 2000, we noticed a heavy outbreak of Fusarium patch in another area, and decided to start the fungicide program in that area on 8 November 2000, and called it Experiment B. Both experiments were evaluated for Fusarium patch injury every two weeks until 27 November, and then for pink snow mould injury after snowmelt on 30 March and 19 April 2001. The results from the two experiments demonstrated that a light level of Fusarium patch infection in the fall (<10% area affected) could be managed by a single late fall snow mould [fungicide application to prevent heavy pink snow mould] development in the winter. In the lightly infected area, the application of fungicides from early to late fall to control Fusarium patch did not significantly affect the level of snow mould after snow melt since the single snow mould fungicide application was just as effective. However, if heavy levels of Fusarium patch are allowed to develop in the fall, then mid to late fall fungicide applications (iprodione) to control Fusarium patch may be insufficient to prevent a high level of pink snow mould after snowmelt even with a snow mould fungicide application (quintozene) in late fall." |
