QUALITY-CONTROL PROCEDURES IN HERBICIDE FIELD DISSIPATION STUDIES

Characterization of herbicide dissipation under field conditions is an important component in determining the environmental impact of herbic ides, and much information is available on this subject. However, this research area could be improved by standardizing and implementing sev eral quality control procedures. The purpose of this review is to eval uate the recent literature on herbicide dissipation published in journ als of the Weed Science Society of America. This review is not compreh ensive with respect to all experimental parameters associated with fie ld dissipation studies, but it is aimed at addressing specific areas o f concern in the experimental approach to this research.
