| Reduced Risk Status: |
|
| IPM Compatibility: |
PER REQUESTOR VERY GOOD FIT, LOW HUMAN TOXICITY COMPARE TO PARAQUAT; SHORT-TERM SOIL LONGEVITY MAY ELIMINATE CONTAMINATION IN HOP CONES THROUGH THE SOIL DUST LIKE IS LIKELY OBSERVED IN PARAQUAT; RESISTANCE MANAGEMENT IN THE WESTERN USA AS GROUP 14 CASES ARE NOT YET PRESENT AND IN OREGON MANAGEMENT OF GLUFOSINATE-RESISTANT RYEGRASS;
|
| Reasons for need: |
CANADA THISTLE, ITALIAN RYEGRASS, KOCHIA OTHER ANNUAL DICOTS, AND MONOCOTS; POTENTIAL REPLACEMENT FOR PARAQUAT IN HOPS ACTIVITIES IN GRASSES WILL IMPROVE WEED CONTROL COMPARED TO CARFENTRAZONE

| Residue Protocol Use Pattern: |
USE THE REVITON PRODUCT (2.83 LB AI OF TIAFENACIL ACTIVE INGREDIENT/GAL OF PRODUCT); MAKE 3 APPLIC OF 0.066 LB AI/A, IN 10-20 GPA, 21-DAY INTERVAL, 14-DAY PHI; DO NOT USE HOP PLANTS LESS THAN 6 FT TALL; APPLY SPRAY IN 2-3 FT WIDE SWATH EXTENDING OUT FROM THE BASE OF HOP PLANTS TO BOTH SIDES OF THE ROW WHILE PROPERLY OVERLAPPING SPRAY PATTERN ACROSS THE LOWER 2 FT OF THE HOP PLANTS TO CREATE A BROADCAST SPRAY PATTERN COVERING A 4-6 FT SWATH; DO NOT CONCENTRATE THE TEST SUBSTANCE IN THE TREATED AREA; ALL APPLIC SHALL INCLUDE A LABELED RATE OF AN ADJUVANT

| E/CS Research Comments: |
IN THE PERFORMANCE PROTOCOL FOR 2022 TRIALS: EVALUATING PERFORMANCE OF TIAFENACIL (REVITON 2.83 SC); EACH TRIAL WILL LAST 2 YEARS, WITH TREATMENTS APPLIED TO THE SAME PLOTS IN YEAR 2; TESTING 2 RATES OF REVITON (0.044 AND 0.088 LB AI/A, PLUS A METHYLATED SEED OIL [MSO] AT 1% V/V AND AMMONIUM SULFATE [AMS] AT 8.5 LB/100 GAL OF SPRAY SOLUTION), IN 15-20 GPA, COMPARED TO THE STANDARD CARFENTRAZONE; IN EACH REVITON TREATMENT MAKE 3 APPLIC (SEE PROTOCOL FOR DETAILED APPLIC TIMINGS AND OTHER REQUIREMENTS); EVALUATE CROP INJURY, DEFOLIATION, CROP HEIGHT, CROP YIELD AND WEED CONTROL; THE 2023 PERFORMANCE PROTOCOL CONTINUES TRIALS BEGUN IN 2022, ON THE SAME PLOTS; 2024 PERFORMANCE PROTOCOL COVERS YR 2 FOR THE ID TRIAL
