Cinmethylin controls multiple herbicide‐resistant <i>Lolium rigidum</i> and its wheat selectivity is P450‐based

Cinmethylin is effective in controlling multiple-resistant L. rigidum and appears safe for wheat when the seed is separated at depth from the herbicide applied to the soil surface. The basis of this metabolism-based selectivity is likely regulated by cytochrome P450 monooxygenases. © 2020 Society of Chemical Industry.
