Northeast Research and Demonstration Farm
Use of foliar fungicides and insecticides are an effective strategy for managing foliar diseases of soybean. There are many different fungicides and insecticides available for use currently in Iowa. Iowa State University personnel assessed the success of fungicides and insecticides across Iowa. This study was conducted at six research farm locations: Sutherland (NW), Kanawha (NC), Nashua (NE), Ames (central), Crawfordsville (SE), and Lewis (SW) (Figure 1).
