| Abstract/Contents: | "Six treatments (combinations of fungicide ? rainfall) were evaluated on a 72-year-old sward of creeping bentgrass in southern Ontario during November 2000 to April 2001 for snow mould control. Inocula of Typhula incarnata and Microdochium nivale were applied on 6 November 2000. Nutri-Q 0-0-5 (N-P-K) with 5% quintozene (=PCNB=pentachloronitrobenzene) at 4.6 kg / 100 m2 was applied at set times during the fall. The plots were evaluated for Fusarium patch injury on 6 and 27 November 2000, and snow mould injury on 23 March (after snow melt) and 19 April (after greenup) 2001. Most quintozene treatments showed significant suppression of snow mould when they were applied within three weeks prior to permanent snow cover whether or not there were rainfall events after fungicide application. The treatment of 6 Nov (5 weeks prior to permanent snow cover) showed reduced efficacy. Between 6 Nov and 13 Dec, there were several occurrences of rainfall or snowfall with snowmelt which could account for the reduced efficacy. Another interesting result was that the fungicide application on 15 Dec also was not efficacious perhaps because the snow removal and snow replacement operations altered conditions required for efficacy of this granular product particularly against grey snow mould." |
