Description

Glyphosate, known by many trade names, including Roundup, is a highly effective herbicide. Widespread glyphosate use for corn and soybean has led to glyphosate resistance, which is now documented in 14 weed species affecting U.S. cropland, and recent surveys suggest that acreage with glyphosate-resistant (GR) weeds is expanding. This report addresses several issues raised by the spread of GR weeds. Choices made by growers that could help manage glyphosate resistance including using glyphosate during fewer years, combining it with one or more alternative herbicides, and not applying glyphosate during consecutive growing seasons. As a result, managing glyphosate resistance is more cost effective than ignoring it, and after about 2 years, the cumulative impact of the returns received is higher when managing instead of ignoring resistance. Figures and tables. This is a print on demand report.
