More changes to US EPA crop groups
The US EPA has made further changes to its crop grouping categories for pesticide tolerance-setting purposes. The latest revision expands the existing stone fruit and tree nut crop groups by adding commodities and establishes new crop sub-groups. It is the third in a series of revisions to crop groupings following petitions from the USDA’s minor-use IR-4 Project. The latest changes take effect on October 22nd.
