✦ Synopsis
Since their introduction in the early 1980s, there have been a number of Ðeld studies conducted to assess the e †ects of sulfonylurea herbicides on nontarget plants (i.e. plants not labeled for use). In these studies a wide variety of plant response assessment techniques have been used to measure e †ects on nontarget plants. This paper examines the relationship of short-term plant response measurements to plant productivity measurements such as yield or quality. Whether short-term plant response measurements have a practical degree of accuracy and precision appropriate for hazard assessment on non-target plants from sulfonylureas is discussed. A comprehensive review of published literature and unpublished Ðeld studies of the e †ects of sulfonylureas on the yield and quality of non-target plant species is reported. When this information is coupled with exposure factors and environmental fate characteristics, the risks to nontarget plants from sulfonylureas are similar to those from other herbicides used at higher application rates.
