4331. McGill, Steve. 1990. Handling herbicide resistance in Russian thistle.. The Furrow (April 1990, NW edition).
Herbicide resistant biotypes of Russian thistle have been identified for Glean and Finesse. These herbicides can no longer be used alone for this weed. More tillage may have to be substituted in some situations, and implements which leave maximum surface residue are recommended. A heavy infestation of Russian thistle reduced yields of spring wheat 11% in a wet year and 55% in a dry year, so control is important for moisture conservation.
