The 2026 label is written in weather. Prove yours.
On February 6, 2026, EPA registered Engenia, Stryax and Tavium for over-the-top use on dicamba-tolerant soybeans and cotton in 34 states, for the 2026 and 2027 growing seasons only, with what EPA calls the strongest protections in agency history. Almost every hard limit on the new labels is a weather number: wind between 3 and 10 mph measured at boom height, a NOAA/National Weather Service forecast high checked for the day of and the day after application (95 F stops the job outright, 85 to 95 F triggers a 50% acreage restriction), no application when rain that may exceed soil field capacity is forecast within 48 hours, and a daylight window from one hour after sunrise to two hours before sunset. When drift is alleged months later, the question is what those numbers were at your field, and whether anyone can still check the record. This page issues a signed, independently re-verifiable receipt of what public weather sources report for your location against those windows, right now.
Six label windows, one signed receipt.
Enter your field's coordinates (or a nearby town). Dynamic Feed runs six checks against the live conditions and a two-day multi-model forecast: the 95 F no-application line and the 85 F restriction band on the forecast high, forecast rain today and tomorrow for the 48 hour rule, the 3 to 10 mph wind window, and the observed conditions. It returns one Ed25519-signed Decision Receipt produced by /v1/answer. Nothing is mocked and nothing is stored about you.

The label runs on forecasts, and forecasts get overwritten.
The 2026 labels do something unusual: they regulate on forecast weather. The applicator must obtain the NOAA/National Weather Service daily high forecast for the day of and the day after application, and the 85 F and 95 F rules bind on that forecast. But public forecasts are overwritten every few hours; months later, "what was the forecast high that day" is no longer a lookup anyone can do from the open web. That is why Dynamic Feed archives a signed multi-model forecast snapshot daily: the companion record at /forecast-record keeps that question answerable, with the signature proving the snapshot has not been altered since it was taken.
The record-keeping burden is real. The federal label enumerates 24 required record items per application, including the air temperature at boom height at the start and at every tank refill, documentation of the NOAA/NWS forecast for both days, and wind speed and direction at or above boom height at the start and at every refill. EPA states plainly that these records exist to enable enforcement, with FIFRA civil fines and, for knowing violations, criminal prosecution. A receipt from an independent witness, signed at the moment and verifiable years later against a published key, corroborates the applicator's own required records. It works against us just as well as it works for you: anyone can re-check it, including the other side.
And the federal label is the floor, not the ceiling. State rules stack on top of it. Minnesota, for example, bars application south of Interstate 94 after June 12 and north of it after June 30, and adds its own 85 F temperature cap. Several other states set calendar or growth-stage cutoffs the federal label does not. Check your state's rules before you spray.
Evidence, not a compliance ruling.
Dynamic Feed is a neutral witness, not a regulator, certifier or adviser. This receipt is not a compliance determination and not legal advice. It does not detect temperature inversions or saturated soil at your site, and the downwind buffers, DRA/VRA tank-mix requirements and runoff/erosion mitigation-point documentation on the 2026 labels are procedural duties this receipt cannot discharge. Labels differ by product and by state, and they change; read your own. This is advisory evidence beside the applicator's own required records, tamper-evident not tamper-proof, with zero personal data.
One API call per application.
