| 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;

| E/CS Research Comments: |
PER THE 2024 PERFORMANCE PROTOCOL: TESTING 5 RATES OF DUAL MAGNUM APPLIED PRE-EMERGENCE BROADCAST (ONE APPLIC OF 0.625, 1.25, 1.875, 2.5 AND 5.0 LB AI/A) AFTER SEEDING BUT PRIOR TO WEED OR CROP EMERGENCE, COMPARED WITH 4 RATES APPLIED EARLY POSTEMERGENCE (ONE APPLIC OF 0.625, 1.25, 1.875 AND 2.5 LB AI/A) WHEN CARINATA IS IN THE 3-6 LEAF STAGE, ALL IN AT LEAST 10 GPA; IN ORDER TO ACTIVATE THE HERBICIDE, AT LEAST 0.5 INCH OF WATER (RAIN AND/OR IRRIGATION) IS NEEDED WITHIN 2 DAYS AFTER APPLIC; EVALUATE CROP INJURY, WEED CONTROL AND CROP YIELD

X-ref with pr# 10971, but treat this as a new request (not a similar supporting request):05/23/sb; the MFG supports this request for the commercial product Dual Magnum and requires a letter of support from COI/CRO:5/23/sb; Syngenta supports this request as "Researchable, residue & e/cs data needed:06/23/sb; EPA GREEN: 08/23; the performance protocol was signed 1/3/24, so I have now updated the status to E/CS Data Ongoing. This will be updated to Res & E/CS ongoing once the residue protocol is signed:02/24/sb
