| E/CS Research Comments: |
IN THE 2023 PERFORMANCE PROTOCOL: TESTING 2 RATES OF QUINSTAR 4L (0.375 AND 0.75 LB AI/A), APPLIED 3 TIMES OVER 2 YEARS WITH A HOODED/SHIELDED SPRAYER, AS BANDED APPLIC TO THE SOIL ON BOTH SIDES OF STRAWBERRY BEDS, IN AT LEAST 15 GPA, COMBINED WITH A QUINSTAR LABEL RECOMMENDED ADJUVANT; 1ST APPLIC OF TRMTS WILL BE IN THE ESTABLISHMENT YEAR 2023, ABOUT 5-6 WEEKS AFTER PLANTING; 2ND AND 3RD APPLIC WILL BE IN 2024, WITH FINAL (3RD) APPLIC AFTER FINAL BERRY HARVEST IN 2024 (SEE PROTOCOL FOR MORE DETAILED APPLIC REQUIREMENTS); EVALUATE CROP INJURY AND VIGOR, WEED CONTROL EFFICACY AND CROP YIELD; PER THE 2024 PROTOCOL, TEST THE SAME RATES, GPA, # OF APPLIC, INTERVAL, BUT SEE PROTOCOL FOR SOME APPLIC TIMING AND METHOD CHANGES FROM EARLIER YEAR TESTING
