Fusarium patch
Fusarium patch is a disease in turf grass settings called pink snow mold, Microdochium patch or Fusarium patch. ''Microdochium nivale'' is the pathogen that causes this disease in many cool season turf grass species in North America.〔Chang, T. , Chang, S. , & Jung, G. (2011). Response of bentgrass cultivars to
microdochium nivale isolates collected from golf courses. Plant Pathology Journal, 27(3), 232-241〕 The white-pink mycelium on infected leaf blades is a distinguishing characteristic of the ''Microdochium nivale'' pathogen.〔() Latin, R. (2007) Pink snow mold and Microdochium patch. Turfgrass Disease Profiles. Purdue Extension, Purdue University〕 Fusarium patch is considered economically important in the turf grass industry because of its tendency to cause significant injury to golf greens, thereby decreasing putting surface quality.〔() Bertrand, A., Castonguay, Y., Azaiez, A., and Dionne, J. (2011). "Cold-induced responses in annual bluegrass genotypes with differential resistance to pink snow mold (Microdochium nivale).", Plant Science, 180(1), pp. 111-119. 〕 Dissimilar from other snow molds, such as gray snow mold, ''Microdochium nivale'' does not need snow cover to cause widespread infection.
==Hosts and symptoms==
''M. nivale'' can infect all cool-season turf grass species.〔() Latin, R. (2007) Pink snow mold and Microdochium patch. Turfgrass Disease Profiles. Purdue Extension, Purdue University〕 Annual bluegrass (''Poa annua''), perennial ryegrass (''Lolium perenne'') and creeping bentgrass (''Agrostis stolonifera'') are more susceptible. In the fall, ''M.nivale'' infection begins as small, orange to red-brown spots, circular and only a few centimeters in diameter. During the winter and into the spring seasons, well-defined, clustered, circular patches 10-20 cm in diameter, of necrotic leaf tissues form on mown turf. ''Microdochium nivale'' is mostly seen on grasses mown at heights of three inches or greater.〔() Latin, R. (2007) Pink snow mold and Microdochium patch. Turfgrass Disease Profiles. Purdue Extension, Purdue University〕 On taller grass, patches often lack a circular pattern that is seen in shorter mown grass,〔() Latin, R. (2007) Pink snow mold and Microdochium patch. Turfgrass Disease Profiles. Purdue Extension, Purdue University〕 On taller grass patches often lack a circular pattern that is seen in shorter mown grass. Pink snow mold patches usually follow drainage patterns since conidia spores are readily dislodged and transported by rainfall and water flowage.〔() Latin, R. (2007) Pink snow mold and Microdochium patch. Turfgrass Disease Profiles. Purdue Extension, Purdue University〕 Under prolonged cool and wet conditions, white-pink mycelium can be observed along the circumference of diseased patches.〔(T. 2007.
