Acetohydroxyacid synthase (AHAS) inhibitor herbicides currently comprise the largest site‐
of‐action group (with 54 active ingredients across five chemical groups) and have been …

Herbicides that target the enzyme acetolactate synthase (ALS) are among the most widely
used in the world. Unfortunately, these herbicides are also notorious for their ability to select …

In input-intensive cropping systems around the world, farmers rarely proactively manage
weeds to prevent or delay the selection for herbicide resistance. Farmers usually increase …
