Resistance to pesticides, genetic traits and other control practices continues to show up in weeds, insects and disease pathogens in Iowa. If this problem isn’t addressed, crop yields will decrease, or crop production costs will increase — or both. Iowa has taken the lead on the issue by creating and implementing the Iowa Pest Resistance Management Program.

In my last editorial I argued that group action is required if we are to effectively manage field crop pests by concluding, “Some things are too big for anyone to accomplish alone and too important not to try to do together.”  

There is little doubt that productivity gains in corn and soybeans can be attributed, in part, to better pest management, which often relies upon herbicides and insecticides. However these pesticides are becoming less effective.
