| IPM Compatibility: |
PER REQUESTER: VERY GOOD FIT; SULFENTRAZONE PREPLANT AFTER BED FORMATION COULD BE APPLIED IN FIELDS WITH KNOWN NUTSEDGE POPULATIONS. EVEN WITH AS FEW AS 15 YELLOW NUTSEDGE PLANTS PER SQUARE YARD TWO WEEKS AFTER SWEETPOTATO TRANSPLANTING, PREDICTED MARKETABLE YIELD LOSS IS AS MUCH AS 35 PERCENT LESS THAN WEED-FREE SWEETPOTATO:08/22; VERY GOOD FIT: SEE PREV COMMENTS: NER; VERY GOOD FIT: SEE PREV COMMENTS.: SOR; VGF-SOR & NER:08/24;
|
| Reasons for need: |
PERENNIAL NUTSEDGE SPECIES; YELLOW NUTSEDGE IS THE SECOND MOST TROUBLESOME WEED BEHIND PALMER AMARANTH AND THIRD MOST COMMON WEED IN NORTH CAROLINA SWEETPOTATO BEHIND PALMER AMARANTH AND CARPETWEED. S-METOLACHLOR IS THE ONLY HERBICIDE REGISTERED FOR CONTROL AND IT DOES NOT PROVIDE ADEQUATE CONTROL. HALOSULFURON AND EPTC WERE PREVIOUSLY REGISTERED FOR USE IN SWEETPOTATO BUT THEY ARE NO LONGER REGISTERED;

NEED E/CS VALIDATION FROM SEVERAL TRIALS BEFORE RESIDUE WORK CAN BEGIN; Per meeting with FMC: Status changed from "Potential, E/CS data before approval for residue study" to "Tol Est, Needs E/CS Data to add crop/pest", FMC supports pre-emergence use only and requires only crop safety data (not seeking a CA registration) 06/26/ds
