ST. LOUIS — Monsanto and many of its licensees are commercializing Roundup Ready 2 Xtend (RR2X) soybeans this spring, and farmers may have ordered or planted RR2X seed.

Roundup Ready 2 Xtend soybeans are new biotech soybeans that are tolerant to both dicamba and glyphosate herbicides. While RR2X soybeans have been approved for import into China and other major U.S. soy export markets, final approval in the European Union (EU) is expected soon but still pending.

Check with elevator

Recently the American Soybean Association issued a reminder to growers that, because RR2X soybeans still lack import approval into the EU, many grain elevators, soybean processors and other first purchasers have issued notices stating they will not accept RR2X soybeans this fall. Final approval by the EU Commission has been expected for the past few months, is expected soon and before harvest, but cannot be guaranteed.

The American Soybean Association, U.S. Soybean Export Council, and others have been working with both EU and U.S. government officials to press for approval of RR2X and other pending new biotech soybean traits. Chinese import approval of RR2X soybeans was obtained in February, and approvals in other major export markets has also been obtained.

No dicamba use

Growers also should be aware that while RR2X soybeans are tolerant to dicamba and glyphosate herbicides, no dicamba herbicides will be approved for use on RR2X soybeans during the 2016 growing season.

The U.S. Environmental Protection Agency recently proposed a draft label for a dicamba product to be used with RR2X soybeans, and this draft label, as well as anticipated labels for low-volatility dicamba herbicide formulations will NOT be finalized until late this summer or fall. Any use of a dicamba herbicide on RR2X soybeans in-season during 2016 before final labels are approved by EPA and state officials would be a violation of law.
