13631 A S-METOLACHLOR/METOLACHLOR ( SYNGEN,UPL NA ) CARINATA (BRASSICA CARINATA) ( 20A = RAPESEED SUBGROUP ) RESIDUE ON-GOING; E/CS DATA ON-GOING

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; VERY GOOD FIT: SEE PREV COMMENTS.: SOR
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.
EPA Default Residue Trials:
IR-4 Residue Trial Plan: Any 4 (1 processing, maybe 2 since new)
Residue Protocol Use Pattern: USE THE DUAL MAGNUM PRODUCT (7.62 LB AI/GAL OF S-METOLACHLOR ACTIVE INGREDIENT); MAKE 1 BROADCAST APPLIC OF 1.27 LB AI/A, IN AT LEAST 10 GPA, AFTER SEEDING BUT BEFORE EMERGENCE; IN THE TRIAL FOR PROCESSING SAMPLES INCLUDE A 2X RATE OF 2.54 LB AI/A; WITHIN 2 DAYS AFTER APPLIC, 0.5-1.0 INCH OF WATER NEEDS TO BE APPLIED TO THE PLOT IN THE FORM OF RAINFALL OR IRRIGATION; ALL APPLIC SHALL INCLUDE A LABELED RATE OF AN ADJUVANT;
Efficacy/Crop Safety (E/CS) Data Required:
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

Comments: 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; Status updated to res ongoing ecs ongoing 09/24/ds;
