Oklahoma is a major winter wheat, cotton, and sorghum state with the Oklahoma panhandle, Central Plains, and Red River Valley supporting dryland row crop production. Atrazine 4L is currently priced at $10–$14/gallon in Oklahoma markets as of spring 2026, reflecting Great Plains supply chain conditions.
| Benchmark | Price | vs. 2025 |
|---|---|---|
| NOLA barge (national reference) | $9–$13/gallon | +15–25% |
| Oklahoma co-op / distributor | $10–$14/gallon | +23–33% |
| Oklahoma retail delivered | $10–$14/gallon | +25–35% |

Oklahoma sources fertilizer primarily via rail and truck from Texas Gulf Coast producers; proximity to Enid-area nitrogen facilities provides modest pricing advantage.
| Driver | Impact |
|---|---|
| Generic competition | Multiple domestic and offshore generics keep atrazine prices stable and competitive. |
| EPA regulatory risk | Ongoing EPA review creates long-term uncertainty; near-term supply is unchanged for 2026. |
| Corn acreage | Atrazine use is primarily in corn; state corn acreage directly drives local demand volume. |
| Formulation choice | 90DF (dry flowable) typically costs less per pound of AI than 4L liquid formulations. |
