The Dirty Dozen

A recent survey asked Cereal Newsletter recipients what are their top two weed problems. Several people complained that two weeds were not enough and insisted on adding more weeds to their lists. The number one weed problem identified was downy brome. This is not surprising, and Russian thistle was a close second, just beating out kochia. Jointed goatgrass and field bindweed round out the top five for cereal producers in Umatilla County.
