Pink snow mold

Microdochium nivale


The snow mold pathogen is one of the seedling parasites of winter rye. It is found mainly in harsh and alpine locations, where it damages shoots, but especially roots.

Damage symptoms

Snow mold causes emergence damage. Shoots, but especially the roots are damaged and killed by the pathogen.

Host plants

Snow mold occurs in all types of cereals. Especially in winter tongues and especially in rough and alpine locations.


Snow mold is a widespread disease. It is also often found on lawns and ornamental grasses.

Propagation and transmission

The pathogen is both seed- and soil-borne, so infection is possible via seed and via soil.

Economic importance

Infestation with snow mold leads to poor to insufficient field emergence. Infected seed is an initial possibility for failure damage over the winter. In case of severe infestation, plowing may be necessary.

Prevention and control

  • Use of tested and healthy seeds
  • A healthy crop rotation should be followed
  • It is recommended to propagate seeds especially in dry areas
  • If necessary, seed dressing can be carried out
