American Malting Barley Association, Inc. (AMBA) malting and brewing members will not knowingly buy malting barley that has been post-heading treated with herbicide, such as glyphosate, regardless of the barley’s origin. The post-heading herbicide application of glyphosate to malting barley, as a pre-harvest aid to kill weeds, as a desiccant to dry down the crop, or for any other reason is not labeled for use on malting barley in the United States. The use of such treatment on malting barley is strongly discouraged by the North American malting and brewing industry and residue testing is performed.
The AMBA Board of Directors, citing concerns expressed by the organization’s Technical Committee for potential herbicide residues or affects on germination in malt made from treated barley, has voted to disapprove of post-heading treatment of malting barley with herbicides.
