Abstract

Resistance to aryloxyphenoxypropionate and cyclohexanedione herbicides (ACCase inhibitors) was characterized in five green foxtail populations from western Canada. Field histories indicated that these populations were exposed to up to seven applications of diclofop-methyl and sethoxydim over the previous ten years. Major differences occurred among the populations in their levels of resistance and patterns of cross-resistance. With one exception, R/S ratios calculated from GR50 values derived from growth room experiments varied from 2 to 54 depending on the population and herbicide. The exception was UM131 which was at least 75 times more resistant to sethoxydim (R/S > 2981) than the other populations. UM59 was not resistant to sethoxydim. It was also the least resistant to the other herbicides with R/S ratios ranging from 2 for fenoxaprop-p-ethyl to 8 for diclofop-methyl. In comparison, UM8 was resistant to diclofop-methyl, fenoxaprop-p-ethyl, sethoxydim, and tralkoxydim with R/S ratios of 11, 5, > 39, and 27, respectively. In field experiments, shoot dry weights of UM8 treated at two times the recommended rates of these herbicides were reduced by 9, 45, 74, and 49%. In contrast, the susceptible population, UM7, was completely controlled. UM7 and UM8 did not differ in their response to trifluralin, ethalfluralin, quinclorac, propanil and TCA.
