Trp-1999-Ser mutation of acetyl-CoA carboxylase and cytochrome P450s-involved metabolism confer resistance to fenoxaprop-P-ethyl in Polypogon fugax.

This study revealed that P. fugax had multiple alleles encoding plastidic ACCase, and reported for the first time the occurrence of Trp-1999-Ser mutation and non-target-site resistance in this species. Fenoxaprop resistance in AHHY plants was conferred by target-site mutation and P450s-involved enhanced metabolism. © 2019 Society of Chemical Industry.
