Stalk rots cause damage and yield loss in many corn fields across North America each year. Depending on location, stalk rot organisms may include anthracnose, Gibberella, Diplodia or Fusarium, all of which survive in corn residue and are spread to the next crop by wind and/or rain. Stalk rots can reduce corn yield by killing the plant before physiological maturity. They can also cause plant lodging, increasing harvest losses and impeding harvest progress. If ears from a fallen plant come in contact with the ground for an extended period, grain quality may also be reduced. Each of these 4 diseases is briefly explained and shown below, to help growers identify them correctly. Identifying disease issues at harvest makes growers better prepared to select hybrids for the coming season.
Pioneer research teams have developed and characterized a wide lineup of products that are recognized by growers for their ability to help protect against stalk diseases. For more information on corn diseases and hybrid options to manage them, contact your local Pioneer sales professional.
