    A team of Midwestern climate scientists has released a new report with grim predictions about the impact of climate change on the Great Lakes region. The report foresees a growing trend of wetter winters and springs, with increases in heavy rain events leading to flooding, particularly in urban areas with hard surfaces that cannot absorb the excess water. Rural areas will likely see more erosion, and unpredictable cycles of heat and rainfall could undermine agriculture.

  • Researchers study role of natural organic matter in environment

  • These Bt corn plants in LaSalle County, Illinois, have fallen over (lodged) as a result of rootworm damage. Like other Bt plants that are becoming susceptible to rootworm damage in Iowa, these corn plants contain the Cry3Bb1 Bt protein in a field planted year after year in corn expressing the same Bt protein.

    Researcher tracks agricultural overuse of bug-killing technology

    CHAMPAIGN, Ill. - High corn prices are leading many growers to plant corn every year and to overuse pesticides and other bug-killing technology to maximize yields, researchers report. In many instances, pesticides are applied without scouting fields to see if they are needed, violating a bedrock principle of integrated pest management. The result is a biological diversity desert in many corn and soybean fields in the agricultural Midwest, and signs that the surviving insects are becoming resistant to several key bug-fighting tools now available to farmers.
