RESEARCH TRIANGLE PARK, N.C. (AP) -- German chemical company BASF SE says it has received U.S. approval to market a new herbicide to battle broadleaf weeds resistant to a chemical in commonly used herbicides like Roundup.
BASF said Tuesday the Environmental Protection Agency has approved its Kixor herbicide for use in four products that will be offered this fall.
It expects sales to reach about $200 million by 2012.
Growers discovered that some broadleaf weeds have developed a resistance to glyphosate, a key chemical that Monsanto Co. first patented and used in Roundup. BASF says Kixor herbicide will attack those resistant weeds.
A Monsanto spokeswoman declined immediate comment.
