ST. LOUIS(November 5, 2013) –Two farmers from Illinois and Minnesota – both growing Roundup Ready 2 XtendTMsoybeans – are seeing first-hand the efficacy of dicamba for weed control, as well as seeing the value that Diversified Weed Management Practices (DWMPs) can have on their fields.
Both farmers are growing their soybean crops under full-scale commercial conditions as part of the Ground Breakers®Field Trials Under Permit program. Roundup Ready 2 Xtend Soybeans are not yet approved for commercial sale or distribution and dicamba is not yet registered for use over the top of soybeans.
Roundup Ready 2 Xtend Soybeans, upon regulatory approvals, will provide tolerance to dicamba and glyphosate herbicides and help farmers achieve more consistent, flexible control of tough-to-manage and resistant weeds when used in a program with a recommended soil residual herbicide. Roundup Ready 2 Xtend technology is built upon Genuity®Roundup Ready 2 Yield®Soybean technology.
A growing number of farmers are realizing the benefits of DWMPs that include a combination of pre-emergence residual and overlapping residual herbicides with multiple modes of action. Residual herbicides can provide weed control of 30 days or longer, which allows soybeans to reach canopy more quickly and makes postemergence herbicides such as dicamba and glyphosate more effective for the near- and long-term future.
Jim Hild, a Ground Breakers®Field Trials Under Permit farmer from Central Illinois, is in his second year of growing Roundup Ready 2 Xtend Soybeans under the Ground Breakers Field Trials Under Permit program. Hild reports he is impressed with the timeliness and effectiveness of weed control using dicamba and glyphosate paired with residual herbicides in Roundup Ready 2 Xtend Soybeans.
“With Roundup Ready 2 Xtend soybeans, we see excellent weed control,” Hild reports regarding the use of the dicamba and glyphosate he applied at burndown prior to planting. “The extra mode of action with dicamba has proven to be effective and efficient. The tankmix of dicamba and glyphosate kills weeds quickly and does a great job of keeping our fields clean. The efficiency of the herbicides and residual control was really important to us this year,” Hild explains.
Steve Prokosch, a Ground Breakers Field Trials Under Permit farmer from Southwest Minnesota whose fields have had issues with resistant waterhemp in the past, reports dicamba and glyphosate have worked well together on his farm.
“The dicamba doesn’t kill grass, so you still have the glyphosate and residual herbicides to get the grasses that pop up through the year,” says Prokosch.
Seeing how this technology is providing a critical weed control tool they’ve been needing, Hild and Prokosch agree, an important facet of using Roundup Ready2 Xtend Soybeans is protecting the glyphosate technology.
“Glyphosate is still the most important herbicide we have,” Hild states. “The Roundup Ready 2 Xtend Soybeans gives us the ability to defend and protect the technology against resistant weeds by pairing glyphosate with dicamba and residual herbicides.”
Prokosch emphasizes the importance of glyphosate as a herbicide that controls many weeds.
“Glyphosate is a proven product that has done a very good job for us in the past. Glyphosate is a herbicide that controls most of our weeds. In order to keep using glyphosate, we’ll have to include it in a tankmix with other herbicides – especially residual herbicides – to keep it relevant,” Prokosch says. “We have a lot less weed pressure now since we’ve been using Roundup Ready 2 Xtend Soybeans. We feel the weed seed bank on our farm is decreasing because of the use of dicamba paired with glyphosate and residual herbicides.”
Farmers interested in seeing Roundup Ready 2 Xtend Soybeans under commercial conditions can follow three Ground Breakers Field Use Under Permit farmers and their Roundup Ready 2 Xtend Soybean fields at, www.XtendFollowaField.com. Videos of how the technology worked on their farms will be posted throughout the 2013 growing season.
