Environment
Microdochium nivale becomes problematic when turf experiences lengthy periods of cool, wet weather typical of fall or spring and into early summer in the Northern Hemisphere. The name is somewhat confusing because the presence of snow is not necessary for this pathogen to develop. The disease can thrive under snow cover, however, if it falls on unfrozen soil with thriving turf. In general this disease tends to develop proficiently when grass is growing at a slower than normal rate. Limiting fall N applications in an attempt to decrease the growth of grass and promote dormancy can help decrease the incidence of Pink Snow Mold. In regions of high humidity and temperatures ranging between 32 to 46 degrees Fahrenheit or 0 to 8 degrees Celsius, Pink Snow Mold will develop rapidly.

Famous quotes containing the word environment:
“Autonomy means women defining themselves and the values by which they will live, and beginning to think of institutional arrangements which will order their environment in line with their needs.... Autonomy means moving out from a world in which one is born to marginality, to a past without meaning, and a future determined by others—into a world in which one acts and chooses, aware of a meaningful past and free to shape one’s future.”
—Gerda Lerner (b. 1920)
“Modern man’s capacity for destruction is quixotic evidence of humanity’s capacity for reconstruction. The powerful technological agents we have unleashed against the environment include many of the agents we require for its reconstruction.”
—George F. Will (b. 1941)
“For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.”
—Sara Lawrence Lightfoot (20th century)
