Planning reference, not a live quote: ranges on this page are modeled from public benchmarks and regional assumptions. Confirm the dated local offer, freight, application, delivery window, payment terms, and expiration before acting.
Colorado is a major corn, wheat, and cattle state with the South Platte River corridor, Arkansas River Valley, and eastern plains supporting intensive dryland and irrigated production. Atrazine 4L has a modeled planning range of $10–$15/gallon in Colorado markets as a 2026 planning reference, reflecting Mountain West supply chain conditions.
| Benchmark | Price | vs. 2025 |
|---|---|---|
| NOLA barge (national reference) | $9–$13/gallon | +15–25% |
| Colorado co-op / distributor | $10–$15/gallon | +29–39% |
| Colorado retail delivered | $11–$15/gallon | +31–41% |
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.
Colorado sources fertilizer via Denver-area distributors and Union Pacific rail from Gulf Coast producers; eastern plains farmers pay 10–16% premiums over NOLA benchmarks.
| 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. |
Colorado farmers typically source Atrazine 4L through regional co-operatives, independent retailers, and direct distributor contracts.
