Step 2: Field Scale

  • Symptoms are distributed in an even pattern across the field
  • Affected areas appear stunted with varying stages of development
  • Heavy amounts of oat residue are found throughout the field, less apparent in areas with good growth
  • A gradient of impact is observed from each of the affected areas
  • You pace off the infected area and notice that it is about 12 feet wide, distance between infected areas appear to be approximately 24 feet
