The U.S. Environmental Protection Agency (EPA) has adjusted the maximum residue limits (MRL) of diquat to align with Canada's standards for group 6c (pulse crops). Effective immediately, the new MRL for Group 22 active ingredient diquat in peas, dry beans, and shelled beans is 0.9 parts per million (ppm). This regulation applies to products like Reglone, Reglone Ion, and Desica, which contain diquat and are used as a pre-harvest aid in pulse crops, excluding soybeans. The adjustment was requested by Syngenta Crop Protection.
