Background:

Lodging is when cornstalks are bent or broken. This is caused by numbers of factors, but most often weather, diseases and pests. Lodging has a significant impact on yield and quality of the plant. This is due to the inability to take in sunlight and nutrients. This can be seen mid to late season as the plants have grown.

Factors:

  • Strong winds
  • Rain and storms
  • Disease and pests
  • Nutrient deficiencies
  • Planting density

Management:

  • Plant non-susceptible hybrids.
  • Manage planting density.
  • Apply fertilizers judiciously. (Lodging Iowa State)
