More herbicide-resistant weeds to come?

From Delta Farm Press - What will be the next herbicide-resistant weed?

For a long time weed scientists thought herbicide resistant weeds would never emerge as a problem. They were wrong. “We sat back and watched entomologists struggle with insects resistant (to insecticides) and thought nothing similar would happen on the weed side,” said Bob Scott, Arkansas Extension weed specialist at the annual Arkansas Soybean Research Conference in Brinkley, Ark., on Dec. 15. “We thought there weren’t enough generations in a year, there were too many different herbicides and different biological systems that would prevent weed resistance.”
