Resistance to ACCase-inhibiting herbicides in an Asia minor bluegrass (Polypogon fugax) population in China

- An Asia minor bluegrass population showed resistance to aryloxyphenoxypropionates herbicides.
- Much lower R/S values were detected for cyclohexanediones and phenylpyrazolins herbicides of the resistant population.
- Resistance was associated with mutation (Ile2041 to Asn) of the ACCase gene.
