|---|---|
| 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. |
