ACCase-resistant Italian ryegrass (Lolium multiflorum) is one of the most troublesome weeds in US wheat production systems. This study had the objective of determining the resistance pattern of three subpopulations selected from a winter wheat field with history of ACCase-inhibitor herbicides applications in Oregon. A greenhouse experiment was conducted to test four ACCase-inhibitor herbicides for the control of the three sub-populations: Pinoxaden, clethodim, sethoxydim and clodinafop. All three sub-populations were cross-resistant to the commercial dose of at least two herbicides. One sub-population was cross-resistant to all herbicides tested. This resistance pattern highlights the need of studying different ACCase herbicides for crossresistance, as well as herbicides with different modes of action for multiple-resistance to control these subpopulations. |
