| Reduced Risk Status: |

| IPM Compatibility: |
Per Requester: Very Good Fit; 0 resistance reported, needed as a new herbicide class in repertoir for managing resistance as a pre-emergent
|
| Reasons for need: |
lambsquarters, pigweed, ground cherry. 0 resistance reported, needed as a new herbicide class in repertoir for managing resistance as a pre-emergent:06/24/sb; TX-Add'l chemistries are necessary to prevent resistance in weeds that have a history of resistance to other herbicides (i.e. pigweed):08/24;

| Requesting State(s): |
NM:Robbins, C* ; TX:Cochran, K ;
|
| PCR Use Pattern: |
use pattern changed slightly from the original PCR: Make one broadcast pre-transplant or post-transplant application or 2 post transplant row middle applications of Nortron at 6.0 to 7.5 pt/a. Sequential applications must be at least 10 days apart and no application should be made within 30 days of pepper harvest.

| Comments: |
Likely an export commodity but not defined. Previous OK trial data showed 2 pt/a of Nortron PRE caused 18% stunting. Previous CA trial showed noticeable but transient injury from row middle applications of 3.5 and 7 pt/a. The current Nortron label claims control of lambsquarters, select pigweeds, and groundcherry only at rates used for sugarbeets (6 to 7.5 pt/a):06/24/sb; EPA HOLD CAUTION:08/24/sb; Bayer supports as Residue Only. Bayer also noted “ethofumesate is under special review in Canada. If trade of treated commodity to Canada is important, obtaining iMRLs in Canada may be challenging”:09/24/sb;
