Posted 22 September 2011. Crop Management. Respect the Rotation: Glyphosate-Resistant Weeds One Year Later Source: Bayer CropScience Press Release. www.bayercropscienceus.com Research Triangle Park, North Carolina (September 14, 2011)--Growers, consultants, weed scientists, researchers and government agency officials who participated in the July 2010 launch of the Respect the Rotation™ initiative have taken measureable steps toward progress in the fight against the proliferation of glyphosate-resistant weeds. But university experts still believe the system will fail if current practices continue.
There is enough of an ominous threat to current agricultural production practices that government officials have taken an interest in the topic. Armed with that knowledge, one initiative to come from the 2010 Respect the Rotation field day urges growers to remember their on-farm management practices from a time before glyphosate resistance was widespread when diverse management practices discouraged the development, and additional cost, of resistant weeds. “Glyphosate-resistant marestail costs soybean growers an added $11.50 per acre,” said Jason Norsworthy, associate professor of weed science at the University of Arkansas and a key member of the Weed Science Society of America (WSSA) who is working with the Environmental Protection Agency to develop guidelines for proper resistance management practices. “Glyphosate-resistant Palmer pigweed costs cotton growers $19.45 per acre. Resistance is impacting land values, conservation tillage and more. The system, the way it is currently set up, is not sustainable.” Norsworthy and other WSSA members are working diligently with other government agencies to develop incentives for proper stewardship of glyphosate-tolerant technologies and encourage proactive management strategies. This cooperation will spur producers to stay ahead of weed resistance and raise a profitable crop. Contact: |
