| Reduced Risk Status: |
|
| IPM Compatibility: |
PER REQUESTOR: VERY GOOD IPM FIT; A PROBLEM WITHOUT A SOLUTION BECAUSE PARTHENIUM IS RESISTANT OR TOLERANT TO ALL HERBICIDES CURRENTLY REGISTERED:07/18; PER 2020 NER NOMINATION COMMENT: EXCELLENT FIT PROVIDED THE LACK OF OTHER HERBICIDES LABELED ON CUCURBITS AND BELONGING TO GROUP 14 AND 15; ADDITIONALLY, THE MIXING OF 2 EFFECTIVE MOA FOR CONTROLLING WEED SPECIES PRONE TO HERBICIDE RESISTANCE (PIGWEEDS) REDUCES THE RISK OF SELECTING FOR HERBICIDE RESISTANCE:08/20
|
| Reasons for need: |
BROADLEAF AND GRASS CONTROL WITH A SPECIAL EMPHASIS ON RAGWEED PARTHENIUM, A WEED FOR WHICH THERE IS NOT CURRENTLY AN EFFECTIVE MANAGEMENT TOOL; RAGWEED PARTHENIUM IS INCREASINGLY PROBLEMATIC AND IS RESISTANT OR TOLERANT TO CURRENT REGISTERED HERBICIDES; PER NJ ME-TOO REQUEST, THERE IS OVERRELIANCE ON THE FEW CURRENTLY LABELED HERBICIDES FOR TOUGH-TO-CONTROL WEEDS SUCH AS COMMON RAGWEED, AND THIS PRODUCT WOULD PROVIDE GREATER FLEXIBILITY AND DIVERSIFY THE NUMBER OF SOA IN AN HERBICIDE RESISTANCE MANAGEMENT PERSPECTIVE; PER NC ME-TOO REQUEST: THERE ARE LIMITED ALTERNATIVES FOR WEED CONTROL IN ROW MIDDLES

| PCR Use Pattern: |
REQUESTOR INDICATED THE PRODUCT AS COBRA (LACTOFEN), BUT THE AI IS SPECIFIED AS FLUMIOXAZIN + PYROXASULFONE, WHICH IS THE FIERCE PRODUCT; USE PATTERN GIVEN IS: MAKE 2 SOIL OR FOLIAR APPLIC, 14 DAYS APART; APPLY AS A PRE TO SOIL OR AS A POST ON PLANTS LESS THAN 5 INCHES TALL; DO NOT ALLOW TO COME IN CONTACT WITH THE CROP; NO RATE OR PHI SPECIFIED; REQUESTOR ASKED THAT THE USE PATTERN BE CLARIFIED TO READ LIKE THAT FOR TOMATO AND PEPPER (PR#S 12576 AND 12577): MAKE 2 PRE APPLIC TO THE SOIL IN ROW MIDDLES, USING A SHIELDED APPLICATOR, 14 DAYS APART:05/19

|
| IR-4 Residue Trial Plan: |
2-2 3 5-2 6; NAFTA 2-3, 3, 5-3, 10
|
| Residue Protocol Use Pattern: |
USE THE FIERCE EZ PRODUCT (1.34 LB AI FLUMIOXAZIN + 1.70 LB AI PYROXASULFONE/GAL OF PRODUCT); MAKE 2 BANDED APPLIC OF 266 ML PRODUCT/A (0.94 LB AI FLUMI + 1.2 LB AI PYROX/A) TO THE SOIL BETWEEN CROP ROWS (USING A HOODED/SHIELDED SPRAYER) IN 10-30 GPA; MAKE THE 1ST APPLIC 5-7 DAYS AFTER TRANSPLANTING, OR IF DIRECT SEEDED AT THE 2-5 LEAF STAGE, AND THE 2ND APPLIC 14 DAYS LATER; ALL APPLIC SHALL INCLUDE A NON-IONIC SURFACTANT OR CROP OIL CONCENTRATE ADJUVANT AT A RATE ON THE FIERCE LABEL (0.25 % V/V FOR NIS OR 1 QT/A FOR COC)
|
| Efficacy/Crop Safety (E/CS) Data Required: |
MIMIC WHAT WAS DONE WITH FRUITING VEG TRIALS; NEED 4 TRIALS; TEST VINING CUCURBITS (SQUASH [12581] AT A FEW SITES) CUCUMBER (12580) AND MELON (12582) IN THE SAME PLOTS; NO CA TRIALS NEEDED AS THIS PRODUCT FIERCE IS NOT TO BE REGISTERED THERE:09/20
|
| E/CS Research Comments: |
MFG SUGGESTS SETTING UP E/CS PROTOCOL LIKE THE TOMATO/PEPPER PROTOCOL - 3, 4.5 AND 6 OZ/A, APPLIED TWICE TO ROW MIDDLES (INTERVAL TBD), BEGINNING WHEN WEEDS ARE 2-4" TALL, NO CONTACT WITH CROP ALLOWED:07/20; PER THE 2021 PERFORMANCE PROTOCOL: TESTING 6, 9, 12 OZ/A OF FIERCE EZ PRODUCT VS A LABELED STANDARD; INCLUDE A NONIONIC SURFACTANT AT 0.25% V/V OR A CROP OIL CONCENTRATE AT 1 QT/A; APPLY IN >5 GPA POSTEMERGENCE TO ROW MIDDLES ONLY; MAKE 2 APPLIC 14 DAYS APART, WITH 1ST APPLIC WHEN WEEDS ARE 2-4 IN TALL AND 2ND APPLIC JUST BEFORE PLANTS VINE INTO THE ROW MIDDLES; EVALUATE FOR CROP INJURY, WEED CONTROL AND CROP YIELD

TOLERANCE IS ESTABLISHED FOR FLUMIOXAZIN ON CUCURBIT VEGETABLES CROP GROUP 9; CANADA AND MEXICO NOTED AS KEY EXPORT MARKETS:07/18; VALENT AND KUMIAI SUPPORT, BUT KUMIAI REQUIRES PERFORMANCE DATA BEFORE APPROVAL FOR RESIDUE WORK:08/18; STATUS UPDATED TO RESEARCHABLE, E/CS ON-GOING; RESIDUE DATA NEEDED:10/22; STATUS CHANGED TO ECS DATA ONGOING:04/23, JPB; ONCE ECS DATA HAS BEEN REVIEWED AND APPROVED BY MFG TO MAKE RESEARCHABLE, ONLY RESIDUE DATA NEEDED THIS PR# WILL NEED TO GO TO THE FUW FOR RESIDUE PRIORITIZATION: 04/23 JPB;; YELLOW 08/23; Status changed from "Researchable. only res data needed" to "Complete w ongoing trials" 03/24/DRS;
