Spraying By The Numbers

摘要

Herbicides are grouped according to family, such as tri-azines, and by the target site of action or mechanism of action, such as acetolactate synthase or ALS inhibitors. Herbicides within a family have similar chemical structures and, typically, the same site or mechanism of action (MOA). Knowing the chemical family and MOA group to which a herbicide belongs and knowing what other herbicides have the same MOA is critical for creating a plan to prevent or delay development of herbicide resistance.
