| Reduced Risk Status: |
|
| IPM Compatibility: |
Per requester: very good fit; winter weeds emerge during three to five weeks of carinata planting. S-metolachlor provides effective control during that time. Brassica carinata canopy is very competitive, so ensuring early weed control to give time for crop canopy closure reduces the need for postemergence herbicide applications 05/23;
|
| Reasons for need: |
Winter Weeds; Carinata acreage is doubling yearly, and there are no effective preemergence herbicides registered for this crop. There is data on safety and efficacy that indicates s-metolachlor is a good herbicide option for this crop 05/23;

| Requesting State(s): |
AR:Wright Smith, H, ; NC:*Leon, R ;
|
| PCR Use Pattern: |
Use Dual Magnum and conduct 1 pre-emergent soil application at 0.95 to 1.3 lbs ai/acre. Within rate ranges, use the lower rate on soils relatively coarse-textured or low in organic matter; use the higher rate on soils relatively fine textured or high in organic matter. Within two days of application 0.5 to 1.0 inch of irrigation or rainfall are needed incorporate and activate the herbicide. PHI not defined.
