Dr. Richard S. Fawcett, consultant and former weed science professor at Iowa State University, conducted an analysis of the Roundup Ready corn system for Monsanto. Enables growers to replace existing herbicides with Roundup , an environmentally and toxicologically superior product.
Invertebrate toxicity is low.
Can contribute to the reduction of trace levels of corn herbicides that are detected in surface and groundwater supplies. The National Water Quality Inventory reports that sedimentation is the greatest polluter of rivers and streams, impairing 45 percent of assessed miles. Sediment also carries nutrients into surface waters, resulting in growth of algae that can result in fish kills when the algae die and decompose. Chlorine, used to disinfect water, can react to organic carbon in sediment to produce trihalomethanes, which are regulated by EPA due to carcinogenicity. No-till has been shown to drastically reduce herbicide runoff into surface waters.
