Book Description
Separate trials related to field weed management led to the first reported case of glyphosate resistance in Russian-thistle from Washington state. Dose response experiments conducted in greenhouse and field settings indicated 2.5 to 8-fold resistance to glyphosate in this accession. Variability in the magnitude of expressed glyphosate resistance appeared closely correlated with temperature conditions after application, with higher temperatures resulting in higher levels of expressed resistance. Resistance to glyphosate poses a substantial threat to successful weed control in chemical fallow in the PNW, which relies heavily on glyphosate. Field experiments were conducted to evaluate several pre-emergence herbicides for addition to glyphosate-only chemical fallow management programs in the wheat-fallow region. Initial results indicate that this approach has potential to improve efficacy of control and reduce selection pressure for glyphosate resistance in chemical fallow, but further experimentation is needed before robust field management recommendations can be developed.
