| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Fit Unknown; Unique Attributes: new agronomic practice of double cropping biofuel crops after corn/soybeans will boost sustainability for growers and the biofuel industry.
|
| Reasons for need: |
Weeds/pests listed on current product label will not change. Winter oilseed biofuel crops may be double cropped after corn and soybeans. Current corn/soy herbicide labels do not allow for 4 months plantback to oilseeds. This request is to develop crop rotational data to support reducing plantback window:08/24;

| Comments: |
Key Export Markets: Mexico, Canada, EU. BASF supports as "Researchable, Needs E/CS Data Only":09/24/sb; No residue data is needed for this project since it is not intended for direct use of topramezone in canola, nor any field accumulation in rotational crop data to avoid inadvertent residues because the requested 4 month interval is greater than the regulatory interval for rotation to non-labelled crops. The current labeled rotational crop interval to canola following topramezone product use in corn is 9 to 18 months depending on use rate. BASF could support an interval of 4 months to canola at the lower topramezone product uses rates, assuming E/CS safety data is provided to prove acceptable follow crop safety and BASF requires at least 3 follow crop trials to evaluate follow crop safety to canola:09/24/AA/sb
