Overexpression of cytochrome P450 CYP71AF43 contributing resistance to fenoxaprop-P-ethyl in Alopecurus myosuroides from China.

Black-grass (Alopecurus myosuroides), one of the most economically destructive herbicide-resistant weeds in Europe, is rapidly expanding in winter wheat regions of China. In recent years, the recommended application rate of fenoxaprop-P-ethyl in the field has failed to effectively control Alopecurus myosuroides populations, thereby threatening wheat yields at risk. In this study, we collected a suspected herbicide-resistant population (R-HB) of Alopecurus myosuroides from a wheat field in Hebei Province and confirmed its resistance to fenoxaprop-P-ethyl, with a resistance index of 26.

Cytochrome P450 and Glutathione S-Transferase Are Linked to High-Level Resistance to Glufosinate.

has become a global nuisance weed and has evolved resistance to glufosinate. The involvement of target-site resistance (TSR) in glufosinate resistance in has been elucidated, while the role of nontarget-site resistance (NTSR) remains unclear. Here, we identified a glufosinate-resistant (R) population that is highly resistant to glufosinate, with a resistance index of 13.

First Asp-2078-Gly Mutation Conferring Resistance to Different ACCase Inhibitors in a Population from China.

Asia minor bluegrass () is a common and problematic weed throughout China. that is often controlled by acetyl-CoA carboxylase (ACCase) inhibitors in canola fields. Herein, we confirmed a population (R) showing resistance to all ACCase inhibitors tested with resistance indexes ranging from 5.
