13750 A MESOTRIONE ( SYNGEN,UPL NA ) SESAME ( 20A = RAPESEED SUBGROUP ) RESIDUE ON-GOING; E/CS DATA ON-GOING

Reduced Risk Status: THIS AI HAS BEEN CLASSIFIED AS RR FOR ONE OR MORE FOOD USES.
IPM Compatibility: Per Requester: IPM Fit Unknown with N/A for explanation of the fit; UNKNOWN: : SOR
Reasons for need: Broadleaf weeds, specifically: amaranth sp., false ragweed, kochia, marestail, volunteer beans/peas; Currently sesame has few preemergent options, and all are labeled for 30-45 days preplant which does not work well in most systems. Mesotrione provides a preemerge option that can be applied close to or after planting and provides a new andw unique mode of action:08/23
Requesting State(s): AR:Smith, H ; NC:Post, A ; OK:Luper, C ; TX:De La Fuente, G* ;
PCR Use Pattern: Make one preplant or preemergence application at 1 to 6 fl oz/a to control troublesome broadleaf weeds; future efficacy and crop response trials should look at pre-plant applications as well (7 to 14 days).
EPA Default Residue Trials:
IR-4 Residue Trial Plan: Any 4 (processing)
Residue Protocol Use Pattern: USE THE CALLISTO HERBICIDE PRODUCT (4 LB AI/GAL OF MESOTRIONE ACTIVE INGREDIENT); MAKE 1 SOIL BROADCAST APPLIC OF 0.188 LB AI/A IN 10-60 GPA, WITHIN 48 HRS AFTER PLANTING, FOLLOWED BY AT LEAST 0.5 IN OF IRRIGATION OR RAINFALL AFTER AND WITHIN 7 DAYS OF EMERGENCE; IN THE TRIAL FOR PROCESSING SAMPLES, INCLUDE A 2X RATE OF 0.376 LB AI/A, WITH THE SAME APPLIC AND POST-APPLIC DIRECTIONS; ALL APPLIC SHALL INCLUDE A LABEL RATE OF AN ADJUVANT
Efficacy/Crop Safety (E/CS) Data Required:
E/CS Research Comments: PER THE 2024 PERFORMANCE PROTOCOL: TESTING MESOTRIONE TO SUPPORT REGISTRATION ON SESAME; ALL SITES WILL USE THE VARIETY 'S2431' PROVIDED BY SESACO; TEST 5 RATES OF CALLISTO (0.0625, 0.094, 0.125, 0.19, 0.25 LB AI/A) ALL APPLIED IN 10-60 GPA, USING 2 DIFFERENT TIMINGS (PREPLANT BROADCAST 7-10 DAYS BEFORE SEEDING, AND PREEMERGENCE BROADCAST AFTER SEEDING THE CROP BUT BEFORE CROP EMERGENCE); SEE PROTOCOL FOR MORE APPLIC REQUIREMENTS; EVALUATE CROP INJURY AND CROP YIELD; WEED CONTROL DATA ARE OPTIONAL
Label Use Pattern Submitted To EPA:
EPA PIF Status: Green 12/23
EPA Status:
EPA PRIA Date:
MRID:
Comments: Per PCR, Japan is an export market:02/24/sb; Per requester, currently registered preplant herbicides require long preplant intervals and mesotrione applied just prior to or immediately after seeding will be more useful:08/23; Mfg supports as "Researchable, Residue and E/CS data needed", and future efficacy and crop response trials should look at pre-plant applications as well (7 to 14 days).:08/23/sb; EPA Green 12/23; E/CS ongoing, status will be changed to "Residue ongoing, E/CS ongoing" once residue protocol is signed 02/24/DRS; Res ongoing ECS ongoing 03/24/DRS; The Residue protocol is in the process of being cancelled, and the status will be updated once the amendment process is finalized:06/24/sb
