Fungicide resistance in dollar spot caused by Sclerotinia homoeocarpa is a common problem on golf courses in North America (Figure 1) (2), and managing fungicide resistance is a complex and controversial topic (1,4). With dollar spot, the question of whether to use the same fungicide until resistance develops or to rotate different chemistries and tank mixtures has not been defi nitively answer...

Since their introduction in the late 1970s, phenylamide fungicides have been used effectively to control diseases caused by the Peronosporales. These fungicides have a very specific mode of action; inhibiting fungal ribosomal RNA polymerases (7). Because of this specificity, there is a relatively high risk that resistance to the fungicide may appear quickly in the target fungal population (3). ...

Fusarium head blight (FHB) continues to threaten the economic sustainability of many small grain producers in Manitoba by causing losses in grain yield and quality. In this 2-year study, four fungicides were tested on two spring wheat cultivars with different levels of resistance to FHB inoculated with 3ADON and 15ADON chemotypes of Fusarium graminearum. All fungicides (prothioconazole, tebucon...
