| Reduced Risk Status: |
|
| IPM Compatibility: |
PER REQUESTOR: VERY GOOD IPM FIT; WEED ESCAPES ARE MONITORED AND WEEDS WOULD BE PRESENT BEFORE APPLIC WOULD BE MADE; USE OF METRIBUZIN COULD DECREASE REPEATED MECHANICAL BETWEEN-ROW CULTIVATIONS; ADDITIONAL MODE OF ACTION HERBICIDE MAY DECREASE SELECTION PRESSURE ON PPO INHIBITOR RESISTANCE:12/16; VERY GOOD FIT: SEE PREV COMMENTS.: SOR
|
| Reasons for need: |
BROADLEAF WEEDS; THERE ARE NO HERBICIDES REGISTERED FOR BROADCAST APPLIC TO SWEET POTATO WITH POSTEMERGENCE ACTIVITY ON BROADLEAVES; POST CONTROL IS LIMITED TO HAND REMOVAL AND REPEATED CULTIVATION

THIS USE CAN BE COVERED WITH ONGOING METRIBUZIN/POTATO STUDY (PR# 10671); WILL BE REQUESTING A TOLERANCE FOR SUBGROUP 01C TUBEROUS AND CORM VEGETABLES, WHICH INCLUDES SWEET POTATO:12/16; TO BE COVERED BY PR# 10671:05/17; THE POTATO PR# 10671 STUDY (AND THE CROP SUBGROUP 1C TOLERANCE THAT WAS EXPECTED) THAT WAS TO COVER THIS FOLIAR BROADCAST USE PATTERN ON SWEET POTATO IS BEING CANCELED DUE TO ANALYTICAL ISSUES THAT CAN'T BE RESOLVED; A NEW PR# WILL BE CREATED FOR THAT REQUESTED USE ON POTATO, AND THUS THE STATUS OF THIS REQUESTED USE IN SWEET POTATO IS CHANGED FROM COVERED BY ANOTHER PROJECT TO RESEARCHABLE SO IT CAN BE PRIORITIZED:05/20; EPA HOLD:08/20; EPA REMOVED HOLD 2/23 & ADAMA NOW REQUESTS RESIDUE & E/CS:03/23/sb; E/CS covered under IS00383: 5/23 JPB;; YELLOW 08/23; ADAMA in US & BAYER in CANADA:06/24/sb; EPA GREEN:08/24; status updated to Need E/CS Data only as residue work is covered under existing PR 13027 metribuzin/potato:09/24/sb
