Typhula Blight Severity as Influenced by the Number of Preventive Fungicide Applications and Snow Compaction

Fig. 2. Typhula blight severity on a Kentucky bluegrass (Breckenridge, CO) or an annual bluegrass (Vail,CO) fairway following a single application the first week in November, and just before snow cover, of the systemic fungicide propiconazole commercially mixed with the contact fungicides chlorothalonil and fludioxonil (Instrata 3.6SE, 11 fl oz/1000 ft²), compared to plots receiving two applications of Instrata (5.5 fl oz/1000 ft²) the last week in September or the first week in October and again in early November. There were no differences (P > 0.10) in Typhula blight severity between one and two fungicide applications on any date. Lines indicate standard errors.
