| Reduced Risk Status: |

| IPM Compatibility: |
Per Requester: Very Good 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 applications per season targeting suckers. We are also mixing NAA with latex paint and applying to the trunk to suppress suckers and water sprouts; VERY GOOD FIT: SAME: WSR

| Reasons for need: |
Hazelnut suckers control, 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 applications per season targeting suckers. We are also mixing NAA with latex paint and applying to the trunk to suppress suckers and water sprouts:08/23

| PCR Use Pattern: |
Copied from PR# 13065; 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; Based on guidance on NAA from EPA, MFG suggests the use pattern include the following: Apply product as a directed spray to the lower tree trunks and up to 12 inches (1 foot) around the base of the tree:09/23

The residue project for this study was canceled under PR# 13065, with performance still ongoing, and a new pcr & # was needed to review for residue again, which was rec'd:8/23; Mfg supports as "Researchable, Residue & E/CS Data Needed:08/23; Mfg updated support at 2023 FUW from Researchable, Residue & E/CS data Needed to "Residue only", but with phyto observations with the residue:09/23/sb; EPA Green 12/23; Status updated to complete w ongoing trials 05/24/drs; E/CS completed under PR# P13065, which will now be covered under this PR# 13705:06/24/sb
