Snow Molds on Minnesota Golf Greens1

  1. W. C. Stienstra

Abstract

Abstract

Psychrophilic turfgrass pathogens are of major importance in Minnesota disease control programs. Typhula spp. and Fusarium nivale are the generally recognized causes of snow mold on golf greens. Sclerotinia borealis was found with T. incarnata and T. ishikariensis on several golf courses in northern Minnesota in 1974, 1975, and 1976. T. incarnata is easier to control than T. ishikariensis. Fungicides used to control Typhula spp. are not as effective against S. borealis. Combinations of several snow mold fungicides performed best. Nitrogen fertilizer applications made at the same time as the fungicide treatments did not improve disease control or increase disease damage, but did improve spring turfgrass color and growth responses.
