Addresses the current and future practice of assessing the risk to unintended or nontarget plant species from the use of low-dose, high-potency herbicides on crops and noncrop species. Focus is on the acetolactate synthase (ALSase)-inhibiting herbicides. Several areas of research are identified, including useful residue detection methods, screening methods for protection of ecosystems, probabilistic risk assessment data needs, and mechanisms of long-range residue transport and plant effects. The principles here might apply equally to nonALSase-inhibiting compounds.
