Death of Smooth Bromegrass (Bromus inermis Leyss.) on Organic Soil1

K. E. Myhr, Milo B. Tesar, R. A. Davis and D. J. deZeeuw2

Investigations were conducted in the field and under controlled conditions to determine why smooth bromegrass dies on organic soil during the growing season and its reaction to fungicide treatments and irrigation.

  1. Isolations of fungi from decayed bromegrass roots in the field show that Fusarium spp. are frequent and, apparently, harmful parasites in muck soil.
  2. Fusarium poae was particularly identified with killing of Lincoln bromegrass roots under controlled conditions. Pythium spp. appeared to be associated with similar, but lesser, injury.
  3. Dying of Lincoln bromegrass in the field was detected in the third cutting near the end of the first harvest year.
  4. Dexon fungicide, selected for its specific action against Pythium spp., only partly reduced dying of roots because the fungicide was ineffective against Fusarium spp. Dexon improved Lincoln bromegrass yields on irrigated plots in the third cutting and stands after the end of the first year in the field.
  5. Yields of bromegrass in the field were reduced approximately 18% as a result of relatively heavy irrigation on a muck soil.
