ARP Partners:
A New Era in
Stewardship
The Acetochlor Registration Partnership (ARP) holds and supports the US registration of acetochlor, an active ingredient in several important agricultural herbicides. The ARP partners are Monsanto and Corteva Agriscience. The ARP provides this website in order to help ensure the effective use and stewardship of products containing acetochlor.
The ARP stewardship program contains several elements:
- Protecting Ground Water: the acetochlor ground water soil restriction has been updated
- Surface Water: ARP support the use of surface water Best Management Practices (BMPs)
- Rotational Crops: the list of acceptable rotational crops for acetochlor has been expanded
- Soil Maps: maps showing possible restricted soils are now available in a new format
