A new pest is showing up in Midwest soybean fields and it’s one that researchers recommend farmers should keep an eye on.

Here's a look at what's headlining ag news this past week, from farm safety net payments, grazing policy, seed research and trade news.

The USDA's October WASDE report sharply bumped national corn yield by 2.7 bushels per acre to 181.2, surprising traders who expected closer to a 0.7-bushel cut. Corn production rose 234 million bushels to more than 16 billion, putting it 200 million bushels over last year. 2026/2027 U.S. corn ending stocks jumped 282 million bushels to 1.849 billion, higher than expectations but still within range.

Drought, beef imports and packing plant changes are setting up for a bumpy fourth quarter for the cattle market, according to Terrain senior research analyst Dave Weaber.

An executive order was signed by President Trump on October 5 to allow the purchase of off-road diesel, or dyed diesel, on highways from October 5 through December 31, 2026. For farmers in the thick of harvest, fuel supply and cost are front and center.

With global supply, production costs and geopolitics all in flux, farmers face a tough call on how much 2027 fertilizer to price this fall. Corey Rosenbusch of The Fertilizer Institute says the impact varies by input.

New federal action targets tick-borne diseases and the biosecurity risk that can affect cattle herds and beef demand. President Trump signed S. 2398, the Kay Hagan Tick Reauthorization Act, on Sept. 30, extending funding for vector-borne disease research and regional centers of excellence through 2030.

Corn futures fell sharply in response to the USDA's Sept. 30 Quarterly Grain Stocks report. The report put Sept. 1 corn stocks at 2.095 billion bushels, up 35% from last year and a seven-year high, compared with the 1.918 billion bushels analysts expected. December corn closed down 21.25 cents at $5.0075 per bushel, its lowest settlement since Aug. 19.
