Answer to Question 1

First, determine what snow mold fungi you need to manage. The most common snow molds are gray snow mold or Typhula blight and pink snow mold also known as Microdochium or Fusarium patch. In extreme northern areas you may encounter snow scald or Sclerotinia snow mold and Coprinus or Cottony snow mold. Before the first

heavy snow or cold drizzly weather in autumn or early winter apply a combination of fungicides given in Table 4.5

Answer to Question 2

i. Cultural management practices: Provide for better surface and subsurface drainage. Have the soil tested and maintain the pH between 6 and 7 . Fertilize according to soil tests and local recommendations for the grasses grown. Mow frequently as high as the golf membership will allow using a mower with sharp blades. Water turf thoroughly but deeply during droughts and repeat in 7 to 10 days if the weather remains dry. Increase light penetration and air movement to shady and pocketed turfgrass areas one or more times each year. Follow suggested insect and weed control programs for your area and the grasses being grown.

ii. Chemical practices: Fungicides effective against dollar spot include systemics
