| Reasons for need: |
LATE-SEASON WEEDS/YIELD LOSS & HARVEST EFFICIENCY; FROM PR# 10671, THE REQUESTED NEED IS TO LOWER PHI TO 30-DAY (USE IS CURRENTLY LABELED FOR 60-DAY PHI); PER NJ ME-TOO REQUEST: REDUCED PHI WOULD ALLOW BETTER CONTROL OF SUMMER EMERGING WEEDS; MS - Additional Reason For Need: For use in sweetpotato (plant beds and field production):08/23

| Residue Protocol Use Pattern: |
USE THE METRIBUZIN 75DF HERBICIDE PRODUCT (75% METRIBUZIN BY WEIGHT); FOR CANADIAN TRIALS USE THE SENCOR 75 DF HERBICIDE PRODUCT (75% METRIBUZIN BY WEIGHT); MAKE 2 BROADCAST APPLIC OF 0.5 LB AI/A, IN 10-30 GPA, WITH THE FIRST APPLIC AFTER PLANTING BUT PRIOR TO CROP EMERGENCE, AND THE 2ND APPLIC AT 30 DAYS BEFORE HARVEST; IN THE TRIAL FOR PROCESSING SAMPLES, THE FIRST APPLIC IS A 2X RATE (1.0 LB AI/A) FOLLOWED BY THE SECOND APPLIC WHICH IS A 5X RATE (2.5 LB AI/A)

THIS PR# WAS CREATED FOR FOLLOW-UP RESIDUE RESEARCH NEEDED DUE TO ANALYTICAL ISSUES THAT CAN'T BE RESOLVED IN POTATO STUDY PR# 10671, WHICH HAS TO BE CANCELED; FROM COMMENTS IN PR# 10671: CANADIAN INTEREST; PER PROPOSAL APPROVED BY CHEMSAC/PMRA, JOINT POTATO STUDY REQUIRES THE FOLLOWING TRIALS: US - 1-2 2 3 5-2 9 10 11-4; CANADA - 1-3 5-2 7-2 14-2;10/11; THE PR# 10671 POTATO STUDY (AND THE CROP SUBGROUP 1C TOLERANCE THAT WAS EXPECTED) WAS TO COVER THE REQUESTED SWEET POTATO PLANTING BED (PR# 12866), SWEET POTATO POSTEMERGENCE BROADCAST (PR# 12095) AND TANIER POSTEMERGENCE BROADCAST USE PATTERNS (PR# 06459); THIS NEW PR# 13027 IS FOR A POTATO RESIDUE STUDY TO REPLACE 10671, AND IS RESEARCHABLE SO IT CAN BE PRIORITIZED IN 2020:07/20; EPA HOLD:08/20; EPA REMOVED HOLD 2/23 & ADAMA NOW REQUESTS E/CS ONLY, MAINLY CROP SAFETY:03/23/sb; YELLOW 08/23; Per Adama company meeting in 5/23 status is Researchable, Residue & E./CS Data Needed and "need to assess if plant back data is necessary":10/23/sb; ADAMA has waived the E/CS data requirements so the status has been changed from "Researchable, Residue & E/CS Data Needed" to "Researchable, Only Residue Data Needed":10/23/sb; for the US, IR-4 is being supported by Adama and Bayer is supporting the request in Canada:11/23/sb; Status changed to "Complete w ongoing trials" 03/24/DRS;
