Harrison County was the site of three recent events highlighting local efforts addressing herbicide resistance.
Palmer amaranth has the potential to become a weed pest that threatens farm productivity and profit. Weed Scientist Bob Hartzler visits three places in Iowa where Palmer has been found. Harrison County and the local Herbicide Resistance Project team is the only one successfully mitigating the threat.
With the harvest underway throughout Iowa, rain in some parts of the state is stopping combines from securing kernels from the field. Depending on your location, disease pressure might not have been high. However, rainfall patterns throughout the season, and even over the last several weeks, means we are not out of the woods yet. Ear rots and associated mycotoxins could be problematic as corn sits in the field awaiting harvest.
