摘要

Studies were initiated in Wyoming to determine the potential of grass competition as an alternative to repetitive herbicide treatment or other cultural practices for control of Russian knap- weed. An experiment was established to evaluate the effects of five grass species, including Russian wildrye cv. 'Bozoisky.' Picloram, applied to Russian knapweed during the first frost, reduced Russian knapweed form an average of 80.1/100 live canopy cover which equates to 0/100 control.
