Illinois is the second-largest corn and soybean state, with the Illinois River corridor and central Corn Belt averaging 200+ bu/acre corn yields. Atrazine 4L has a modeled planning range of $9–$13/gallon in Illinois markets as a 2026 planning reference, reflecting Corn Belt supply chain conditions.
| Benchmark | Price | vs. 2025 |
|---|---|---|
| NOLA barge (national reference) | $9–$13/gallon | +15–25% |
| Illinois co-op / distributor | $9–$13/gallon | +15–25% |
| Illinois retail delivered | $9–$13/gallon | +17–27% |
Use this range to prepare questions, not to make a purchase decision. Confirm the dated source evidence and the actual local delivered quote before acting.
Illinois retailers source heavily from NOLA barge terminals via the Illinois River; Chicago-area terminals also supply northern Illinois, giving buyers multiple supply chain options.
| 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. |
Illinois farmers typically source Atrazine 4L through regional co-operatives, independent retailers, and direct distributor contracts.
