Will this be the year we introduce a host of new weed species throughout the U.S.? Could possible boatloads of grain being imported up the Miss. river create this issue? Usually new weed species seem to start in the southern states and gradually move north - (created by past yrs. imports typically only used in the south?) Your thoughts?
