How IR-4 Helps (cont’d)<BR> <BR>Crop Groups and Crop Group Expansion <BR>EPA Crop Groups are based primarily on similar taxonomy and similar growth habits. Tolerances established on a the ‘representative crop’ of a CG apply to all crops in that CG. More ‘bang for the buck’. <BR>Placing ‘orphan crops’ into established EPA crop groups can automatically get a tolerance applied to that crop. (Ex: Reflex/Eggplant) <BR> <BR>Harmonization of International MRLs <BR>Different tolerance levels for the same product/crop combination in different countries can constrict trade. <BR>IR-4 leading international efforts to harmonize MRLs = ‘level playing field’ <BR>
