| Abstract/Contents: | "In the Pacific North-west, there has been an increase in the prevalence of necrotic ring spot on recently established Kentucky bluegrass sodded turfgrass, particularly in inland areas, and take-all patch on sand-based bent putting greens since the early 1980's. During this time, a number of replicated field trials have been conducted to determine the effectiveness, proper timing and rates of a number of DMI fungicides that might be used in the management of these patch diseases. With both diseases, reductions in disease incidence and severity were obtained with a single application of one or more DMI fungicide. With necrotic ring spot, a single application of fungicide, such as propiconazole, fenarimol, epoxiconazole or myclobutanil in April or May provided acceptable levels of control through late summer/ early autumn. In the case of take-all patch, a single application of triadimefon, propiconazole, or fenarimol in early December significantly reduced late spring/ early summer symptom development. Delaying applications until early spring reduced the effectiveness of the DMI fungicides in controlling take-all patch. With both diseases, comparatively high rates (1.53 to 3.06 kg ai/ha) of fungicides were required to give optimal control with a single application." |
