Bean leaf beetle on the decline

This information was summarized from a June 10 teleconference with Iowa State University extension field specialists in crops.

  • Corn ranges from V3 to V8 across Iowa, with the bulk now at about V6. Soybean ranges from not emerged to some V4. Mike White (south central), Jim Fawcett (east central), and Todd Vagts (west central) reported some corn stands were suffering from root rot organisms.
  • The bulk of first cutting alfalfa hay has been taken in southern Iowa, with some cutting still ongoing in the northern two-thirds of the state.
  • George Cummins and Brian Lang (northeast) reported soil washing and lowland flooding problems associated with the torrential rainfall of June 4 in eastern Iowa. Floodwaters subsided quickly in most areas, and stands should recover from the inundation.
  • Drift complaints have picked up across Iowa, with good growing conditions and ample field spraying opportunities occasionally affecting neighboring crops and ornamental plantings.
  • Bean leaf beetle populations seem to be dropping across Iowa.
