Heat, Drought and Goss’s Wilt Can Affect Corn Yields in Iowa

(Continued)

Ames, Iowa —

“Research has shown that pure cultures of the bacterium survive less than two months in soil. However, bacteria found on surface crop residue can survive for at least 10 months,” she said. “Some conservation tillage methods including partially burying infected residue should reduce the survival rates. However, soil conservation measures should always be considered. Also, heat, competition with other microbes and low pH reduce the survivability of the bacterium.”

  • NORTHEY COMMENTS ON IOWA CROPS - October 11

    “The dry weather last week helped crops continue to dry down and allowed nearly half of the state’s soybeans to be harvested.  Unfortunately, fire does remain a risk as the dry weather persists, so farmers should continue to take extra care while working in their fields,” Northey said.  “Harvest remains slightly ahead of the five-year average and will likely continue to advance rapidly if conditions remain dry.”

    As harvest begins around the state, farmers are encouraged to be aware of the potential for development of molds and fungus in corn. Recent warnings by Iowa State University (ISU) Extension and Outreach’s Integrated Crop Management (ICM) staff about hail-damaged corn in northwest Iowa help draw attention to the issue, according to ISU Extension swine program specialist Matt Swantek.
