| 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

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

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
