Abstract/Contents:"Snow mold, caused by two Typhula, species, T. ishikariensis and T. incarnata, is one of the major turfgrass diseases in Wisconsin. Three varieties of T. ishikariensis species were found in Wisconsin. The most effective method for controlling snow molds in chemical treatment. To evaluate the inhibitory effect of four fungicides, the mycelium growth of Typhula isolates was measured on potato dextrose agar (PDA) amended with the fungicides at three concentrations. Propiconizol was the most effective in inhibiting the radial growth of the tested isolates at 1.0 ug a.i./ml of PDA. Ranges of percentage in the growth reduction among the isolates for individual fungicide is as follows: PCNB (0-19%), Propiconizol (73-86%), Azoxystrobin (20-69%), and Chlorothalonil (13-69%). In addition, eight fungicides were applied to two experimental field plots located in northern and central regions of Wisconsin during late fall in 1999 and 2000. The plots were evaluated for disease symptoms after snowmelt in the spring of the following year. The percentage of disease severity averaged for two years in untreated plots were 55.3% and 63.8% in the central and northern regions, respectively. The average percentage range of control value for all fungicides were 41.8 to 78.8% in both regions."
