Rationalized Global Data Requirements

The OECD conducted a comprehensive review of residue data to determine if global zones could be considered to facilitate international cooperation. After this review, the team could not discern zones because of high variability in residues from comparable trials. In many cases, the data reviewed showed just as much variability within a zone as compared to across zones. The data also showed that the pre-harvest climate may not have had as strong of an influence on the residue levels as would have been expected. This indicated that the zoning effect may not be a major factor in determining residues. Unfortunately, neither flnal zone recommendations nor data requirements for international registrations could be suggested based on the review. 

Considering that zones are established for all of North America extending from the tropical southern states of Mexico throughout the United States, including
