Abstract
Farmers are faced with many decisions for pest management options as new technologies are introduced. Pests, such as corn rootworm and nematodes, are persistent and economically important pests in Iowa. Rotating corn with soybean usually reduces corn rootworm pressure, although rotationresistant populations can occur in limited areas of Iowa. New insects, such as the soybean gall midge, also are proving difficult to manage. Diseases supressed with seed treatments and foliar applications continues to be important to Iowa farmers. As resistance issues arise with insects and diseases in Iowa, it is important to investigate alternative methods of suppression. The objective of these trials was to investigate what effect various corn and soybean management practices would have on yield.
