This week on Ag News Daily, we cover two major trade updates. President Trump signed an executive order placing an additional 25% tariff on imports from India. Separately, a broader set of tariff increases also took effect this week. We also cover the USDA’s latest SNAP waivers in six states, along with the continued spread of tar spot in corn-growing areas. John Deere has introduced a new diagnostics tool aimed at improving equipment repair, potentially impacting ongoing right-to-repair discussions. We also highlight Luke Lindberg’s recent confirmation as Under Secretary for Trade and what it could mean for U.S. ag exports. This week’s interview features Dr. Martin Chilvers from Michigan State University. Chilvers shares his research-based insight on tar spot, including how to identify it and how growers can manage it during the season.
