| Reduced Risk Status: |
|
| IPM Compatibility: |
PER REQUESTER: GOOD IPM FIT; GLUFOSINATE IS SAFER THAN SOME REGISTERED ALTERNATIVES SUCH AS PARAQUAT AND DOES NOT HAVE THE PUBLIC SAFETY PERCEPTION CHALLENGES OF GLYPHOSATE; PROVIDES BROADER-SPECTRUM WEED CONTROL THAN PPO-INHIBITING HERBICIDES SUCH AS CARFENTRAZONE AND PYRAFLUFEN; PER 2020 WSR NOMINATION COMMENT: GLUFOSINATE WILL PROVIDE POST EMERGENT WEED CONTROL OPTIONS; AS PART OF AN INTEGRATED WEED MANAGEMENT APPROACH THIS WILL BE A GOOD ALTERNATIVE CHEMISTRY TO COMPLEMENT PRE-EMERGENT HERBICIDES AND OTHER WEED MANAGEMENT PRACTICES:08/20
|
| Reasons for need: |
WEEDS; WEEDS REDUCE ORCHARD EFFICIENCY BY COMPETING FOR RESOURCES (WATER AND NUTRIENTS), INTERFERE WITH CULTURAL PRACTICES SUCH AS IRRIGATION AND MANAGEMENT OF INSECT/PATHOGEN/VERTEBRATE PESTS, AND CAN INCREASE UNDER-CANOPY HUMIDITY IN DENSELY PLANTED TRELLISED KIWI PRODUCTION SYSTEMS; RELATIVELY FEW POSTEMERGENCE HERBICIDES ARE REGISTERED FOR USE IN KIWIFRUIT; THE PRIMARY HERBICIDE, GLYPHOSATE, IS CHALLENGED BY GLYPHOSATE-RESISTANT WEEDS AND ALSO BY CURRENT MARKET CONCERNS ABOUT HEALTH IMPACTS

| Requesting State(s): |
CA:Hanson, B ;
|
| PCR Use Pattern: |
USE THE LIFELINE, OR RELY280 PRODUCT; MAKE UP TO A MAX OF 4 POST EMERGENCE APPLIC OF 0.88-1.49 LB AI/A TO WEEDS, 30-DAY INTERVAL, 14-DAY PHI; DIRECT SPRAY TO VINE ROW; ADD AMS AT 8 LB/100 GAL; DO NOT APPLY THROUGH ANY TYPE OF IRRIGATION SYSTEM, NOR BY AIR; DO NOT CONTACT GREEN BARK, TRUNKS OF YOUNG TREES OR SUCKERS WITH THE SPRAY

| EPA Default Residue Trials: |
10-3
|
| IR-4 Residue Trial Plan: |
10-4
|
| Residue Protocol Use Pattern: |
USE THE LIBERTY 280 SL HERBICIDE PRODUCT (2.34 LB AI/GAL OF GLUFOSINATE-AMMONIUM ACTIVE INGREDIENT); MAKE 3 BANDED APPLIC OF 1.50 LB AI/A TO THE ORCHARD FLOOR IN 15-50 GPA, 14-DAY INTERVAL, 14-DAY PHI; ALL APPLIC SHALL INCLUDE AMMONIUM SULFATE (AMS) AT A RATE OF 3 LB/A; EACH APPLIC SHOULD BE MADE IN BANDS ON EACH SIDE OF THE CROP, WITH A MINIMUM 3-FT SWATH FOR EACH BAND EXTENDING FROM THE BASE OF THE PLANTS; AVOID CONTACTING CROP PLANTS WITH THE SPRAY SOLUTION; THE APPLC RATE IS CALCULATED FOR THE WIDTH OF THE BANDS, NOT THE WIDTH OF THE ENTIRE CROP ROW
|
| Efficacy/Crop Safety (E/CS) Data Required: |
BASF REQUIRES 3 TO 4 CROP SAFETY TRIALS, PRIMARILY IN CA; TRIALS MUST BE MULTI-YEAR WITH SEQUENTIAL APPLIC PER YEAR AT EXAGGERATED RATES (UP TO 3X) ON THE SAME VINES; TOTAL # OF TRIALS DEPENDS ON MATRIX OF IRRIGATION TYPES, SOIL TYPES, VARYING REGIONS OF PRODUCTION IN CA (i.e. PREFER ONE TRIAL PER IRRIGATION TYPE PER REGION); 1X RATE SHOULD BE RELY AT 82 FL OZ/A; BASF REQUESTS SEEDLINGS TO CONDUCT LEVEL OF TOLERANCE WORK IN THE GH
|
| E/CS Research Comments: |
IN THE 2021 PERFORMANCE PROTOCOL: EVALUATING PRODUCT PERFORMANCE IN 3 FUZZY KIWI TRIALS, INCLUDING AT LEAST ONE TRIAL ON NEWLY ESTABLISHED KIWI PLANTS (ESTABLISHED FOR AT LEAST 3 MONTHS); A COARSE TEXTURED SOIL IS REQUIRED AT EACH TRIAL SITE; TESTING 2 RATES OF RELY HERBICIDE, 3.0 AND 4.50 LB AI/A, VS A WEED-FREE UNTREATED PLOT, IN >20 GPA, APPLIED BANDED TO THE ORCHARD FLOOR WITH A MINIMUM 3 FT SWATH ON EACH SIDE OF THE CROP ROW; MAKE 6 SEQUENTIAL APPLIC OF EACH TREATMENT 4 MONTHS APART; ON NEWLY ESTABLISHED KIWI, 1ST APPLIC SHOULD BE MADE TO NON-BEARING PLANTS AT LEAST 3 MONTHS AFTER ESTABLISHMENT; FOR MATURE KIWI PLANTS, 1ST APPLIC SHOULD BE MADE TO WEEDS LESS THAN 6" TALL AND AT LEAST 30 DAYS PRIOR TO THE NEXT HARVEST; DO NOT CONCENTRATE THE AI IN THE TREATED AREA - THE RATE SPECIFIED IS FOR TREATED AREA; DO NOT ALLOW SPRAY SOLUTION TO CONTACT ANY PLANT PARTS, AND NEWLY ESTABLSIHED PLANTS SHOULD BE PROTECTED WITH A NON-POROUS BARRIER (SUCH AS TRUNK WRAPS, GROW TUBES, ETC.);

REQUESTOR CONFIRMED THE NEED IS FOR FUZZY KIWIFRUIT (THERE IS A GRAPE TOLERANCE, WHICH CAN COVER THE HARDY KIWIFRUIT, IF A SUBGROUP 13-07F TOLERANCE IS SECURED); NO KEY EXPORT MARKETS NOTED:01/20; BASF SUPPORTS THIS USE, RESIDUE AND CROP SAFETY DATA NEEDED (NO EFFICACY); EPA GREEN:08/20; TO BE SUPPORTED WITH 2021 CA GRANT FUND $$S:09/20; RESEARCHABLE, RESIDUE & E/CS DATA NEEDED CHANGED TO E/CS DATA ON-GOING AND WILL UPDATE AGAIN ONCE RESIDUE PROTOCOL IS SIGNED:12/20; RESIDUE PROTOCOL SIGNED 03/21; the ASR for CAR is actrually a contributing scientist report and was received 6/12/23, and all residue & e/cs data is now rec'd for this study:12/23/sb
