| Reduced Risk Status: |
|
| IPM Compatibility: |
PER REQUESTER: VERY GOOD IPM FIT; NAA HAS LOWER VOLATILITY WHEN COMPARED TO 2,4-D, AND CAN BE USED SAFELY IN SEASON WITH REDUCED CONCERNS OF CROP DAMAGE; AS IT SUPPRESSES SUCKER GROWTH FOR UP TO FOUR WEEKS, IT CAN HELP REDUCE THE NUMBER OF APPLIC PER SEASON TARGETING SUCKERS:07/20
|
| Reasons for need: |
SUCKER CONTROL; NEED FOR SYSTEMIC LONG LASTING PRODUCT TO SUPPRESS SUCKER GROWTH AND REDUCE NUMBER OF SPRAYS, ALTERNATIVE TO 2,4-D DUE TO CROP SAFETY CONCERNS, REDUCED USE OF PARAQUAT

| Requesting State(s): |
OR:Moretti, M* ;
|
| PCR Use Pattern: |
USE THE TREE-HOLD SPROUT INHIBITOR A-112 PRODUCT; MAKE 2 SOIL DIRECTED BASAL APPLIC OF A 1% AI SOLUTION, V/V, 28-DAY INTERVAL; NO PHI NOTED; APPLY AS A DIRECTED SPRAY TO THE LOWER TREE TRUNKS AND IMMEDIATE SURROUNDING AREA; MAKE 1ST APPPLIC WHEN SUCKERS ARE LESS THAN 1 INCH (USUALLY APRIL TO EARLY MAY IN THE WILLLAMETTE VALLEY); APPLY IN A DILUTE VOLUME OF UP TO 44 GPA, USING A NOZZLE THAT GENERATES COARSE DROPLETS, AND DIRECT THE SPRAY TO THE BASE OF THE TREES; IF NEEDED RE-APPLY IN 28 DAYS; DO NOT APPLY BY AIR; DO NOT ALLOW SPRAY TO SPLASH OR DRIP ONTO OTHER PARTS OF THE TREE; CHANGE IN THE USE PATTER AS AGREED BY REQUESTER AND REGISTRANT- 2 APPLIC, 30 DAYS RETREATMENT INTERVAL; 45 DAYS PHI:04/22

|
| Residue Protocol Use Pattern: |
USE THE TRE-HOLD A-112 SPROUT INHIBITOR PRODUCT (15.1% 1-NAPHTHALENEACETIC ACID, ETHYL ESTER; 1-NAPHTHALENEACETIC ACID (NAA) EQUIVALENT IS 1 LB/GAL OR 13.2% BY WEIGHT); MAKE 2 BANDED APPLIC OF A 1% V/V AI SOLUTION, IN 20-44 GPA, 30-DAY INTERVAL, 45-DAY PHI; EACH APPLIC SHOULD BE MADE IN BANDS ALONG EACH SIDE OF THE TREES, WITH AT LEAST A 3 FT WIDE SWATH EXTENDING OUT FROM THE BASE OF THE TREES, WHILE PROPERLY OVERLAPPING THE SPRAY PATTERN ACROSS THE LOWER 2 FT OF THE TREES TO CREATE A BROADCAST SPRAY PATTERN COVERING A TOTAL BAND WIDTH OF AT LEAST 6 FT; DO NOT CONCENTRATE THE TEST SUBSTANCE IN THE TREATED AREA; EACH APPLIC SHALL INCLUDE A NONIONIC SURFACTANT (NIS) AT 0.25% V/V

| E/CS Research Comments: |
IN THE PERFORMANCE PROTOCOL FOR 2022 TRIALS: EVALUATING PERFORMANCE OF NAA (TRE-HOLD SPROUT INHIBITOR) AND HEALTH OF TREES; EACH TRIAL WILL LAST 2 YEARS, WITH TREATMENTS APPLIED TO THE SAME PLOTS IN YEAR 2; TESTING 2 RATES OF TRE-HOLD (1% AND 2%), WITH ALL APPLIC FOLLOWING USE DIRECTIONS ON THE CURRENT SPECIAL LOCAL NEEDS LABEL FOR OREGON; SEE PROTOCOL FOR DETAILED DESCRIPTION OF DIFFERENT TREATMENTS AND APPLIC REQUIREMENTS; EVALUATE CROP INJURY, SUCKER CONTROL, SUCKER LENGTH AND SUCKER BIOMASS; YIELD DATA ARE NOT REQUIRED; THE 2023 PERFROMANCE PROTOCOL CONTINUES TRIALS ON THE SAME PLOTS STARTED IN 2022
