A new article from our research and extension team on strobilurin-containing fungicide effects in tall fescue seed crops has just been published online in the journal Crop Management, a joint product of the American Society of Agronomy and the Crop Science Society of America.  This work was led by Nicole Anderson, an OSU Field Crops Agent.  The trials were conducted in grower fields from 2010 to 2012.

The study reports several important findings including:

  • Strobilurin-containing fungicides increased tall fescue seed yield by 17% across on-farm sites and years.
  • Tall fescue seed yield was increased even with low incidence and severity of stem rust.
  • Seed yield increases were attributable to a combination of increased seed number and seed weight.
  • Cleanout was reduced by up to 18% with the fungicide treatment.
