|
| PCR Use Pattern: |
USE QUINSTAR 4L; APPLY FOLIAR TO EMERGED WEEDS THAT ARE WELL-ESTABLISHED; APPLY 0.375 LB AI/A IN A BAND DIRECTED TO THE SOIL AT THE BASE OF TREES ON EACH SIDE OF THE ROW, 2 APPLIC 15 DAYS APART; 30-DAY PHI; IF NEEDED INCLUDE 1% COC

JAPAN AND CHINA ARE KEY EXPORT MARKETS; BASF NO LONGER SUPPORTS THIS AI; ALBAUGH SUPPORTS, RESIDUE ONLY, BUT HAS NO PLAN TO REGISTER IN CA:08/18; EPA GREEN:09/19 & 08/20; MFG CHANGED TO POTENTIAL AT FUW (NEED MORE PERFORMANCE DATA BEFORE APPROVAL FOR RESIDUE WORK), AND CONFIRMED THEY WILL SUPPORT REGISTRATION/USE IN CA:09/20; Status changed from "Potential: E/CS Data Before Approval for Residue Study" to "Covered By Another Project". Data is covered under P12572 Quinclorac/Peach 05/24/drs; Albaugh status update from Covered by Another Project to Researchable, Only Residue Data Needed:07/24/sb; EPA Caution:01/25/sb; Status updated to complete w ongoing trials 04/25/ds;
