Interpretive Summary:

Technical Abstract: Several grass and broadleaf weed species around the world have evolved multiple herbicide resistance at alarmingly increasing rates, which is becoming more of a norm than an exception. Research on the biochemical and molecular resistance mechanisms of multiple resistant weed populations indicate a prevelance of herbicide metabolism brought about by enzyme systems such as cytochrome P450 monoxygenases and glutathione-S-transferases, and to a lesser extent, by glucosyl transferases. A symposium was conducted to gain an understanding of the current state of research affairs of metabolic resistance mechanisms in weed species that pose major management problems around the world. These topics as well as future directions of investigations that were identified in the symposium are summarized herein. In addition, the latest information on selected topics such as the role of safeners in crop tolerance to herbicides, selectivity to clomazone, glyphosate metabolism in crops and weeds, and bioactivation of natural molecules is reviewed.
