| Reduced Risk Status: |
|
| IPM Compatibility: |
PER REQUESTER: GOOD IPM FIT; ETHOFUMESATE WOULD REDUCE THE AMOUNT OF HAND WEEDING NEEDED TO PRODUCE THE CROP; IT CAN BE APPLIED WITH OTHER HERBICIDES:04/19
|
| Reasons for need: |
WEEDS; ANNUAL BROADLEAVES AND GRASSES; VERY FEW HERBICIDES LABELED FOR SWISS CHARD; S-METOLACHLOR IS THE ONLY PREEMERGENCE HERBICIDE LABELED FOR CHARD, AND CLOPYRALID IS THE ONLY POSTEMERGENCE HERBICIDE FOR BROADLEAVES; NEITHER HERBICIDE PROVIDES SUFFICIENT WEED CONTROL FOR THE LIFE OF THE CROP; NY/Limited herbicides available in crop. Ethofumesate is labeled for use in NY beets and is a foundational product when used in combination with S-metolachlor to provide residual weed control at planting. Can be used, POST, for extended supression:08/23

MI:Zandstra, B ; NY:Sosnoskie, L ;
|
| PCR Use Pattern: |
USE NORTRON 4 SC; APPLY 1-1.5 LB AI/A PREEMERGENCE AFTER SEEDING AND 0.33 LB AI/A POSTEMERGENCE TO 2-4 LEAF CHARD PLANTS; MAKE 1-2 APPLIC, 30-DAY INTERVAL, 30-DAY PHI; MAX 3 LB AI/A/YR; DO NOT APPLY IF CHARD IS UNDER STRESS
|
| EPA Default Residue Trials: |
ANY 4 TRIALS
|
| IR-4 Residue Trial Plan: |
ANY 4
|
| Residue Protocol Use Pattern: |
USE THE NORTRON SC HERBICIDE PRODUCT (4 LB AI/GAL) OF THE ACTIVE INGREDIENT ETHOFUMESATE; MAKE 1 POST-SEEDING, PRE-EMERGNT BROADCAST APPLIC OF 1.5 LB AI/A IN 10-60 GPA, FOLLOWED BY 1 POST-EMERGENT BROADCAST APPLIC OF 0.33 LB AI/A IN 10-50 GPA AT THE 2-4 LEAF GROWTH STAGE; DO NOT RETREAT WITHIN 10 DAYS OF THE FIRST APPLIC; THE 2ND APPLIC WILL BE 30 DAYS BEFORE HARVEST, AND SHALL INCLUDE A LABELED RATE OF AN ADJUVANT
|
| Efficacy/Crop Safety (E/CS) Data Required: |
|
| E/CS Research Comments: |
PER 2024 PERFORMANCE PROTOCOL: TEST SINGLE APPLIC OF NORTRON SC ALONE AT 1X AND 2X RATES (APPLIED PREEMEREGNCE BROADCAST), VS 2 APPLIC (1ST APPLIC PREEMERGENCE BROADCAST, FOLLOWED BY EARLY POSTEMERGENCE BROADCAST), VS IN COMBINATION WITH DUAL MAGNUM (+ CROP OIL CONENTRATE [COC] WHEN APPLIED EPOST), VS COMMERCIAL STANDARDS, IN 10-60 GPA; NORTRON RATES SHOULD BE PER CURRENT LABEL RATES, AND BASED ON SOIL TYPE; SEE PROTOCOL FOR MORE APPLIC DELIVERY AND TIMING DETAILS; EVALUATE CROP INJURY, CROP YIELD AND WEED CONTROL
