| Reduced Risk Status: |
|
| IPM Compatibility: |
FROM PR# 11429: CONSIDERED VERY GOOD FIT; VERY LOW USE RATE AND LOW HUMAN TOXICITY; PER WSR 2014 NOMINATION COMMENT: SEEMS LIKE A SOLID CASE FOR AN IPM FIT, PRIMARILY DUE TO POTENTIALLY DISPLACING HERBICIDES WITH GREATER LEACHING POTENTIAL; RISK OF RESIDUES IS REALY LOW DUE TO THE NATURE OF THE AI; PER 2020 SOR AND NER NOMINATION COMMENTS: LOW USE RATE AND PHI WOULD BE LONGER BEFORE FIRST HARVEST THAN OTHER MATERIALS, POSSIBLY REDUCING WORKER EXPOSURE; UNIQUE MOA WITH NO KNOWN CASE OF RESISTANCE:08/20
|
| Reasons for need: |
COPIED FROM PR# 11429; ANNUAL WEEDS; DIFFERENT MODE OF ACTION TO AVOID WEED RESISTANCE; CONTROL OF RESISTANT BROADLEAVES; HQ CREATED THIS NEW PR# TO ALLOW FOR RE-PRIORITIZING THIS NEED WITH A REVISED USE PATTERN COMPARED WITH PR# 11429:07/20

| PCR Use Pattern: |
FROM PR# 11429: 0.065-0.085 LB AI/A OF ALION PRODUCT; ONE PREEMERGENCE (TO THE CROP) APPLIC PER YEAR; 7-DAY PHI; APPLY TO CLEAN SOIL BEFORE ASPARAGUS EMERGES IN THE SPRING; BUT THIS PRE-EMERGE USE PATTERN IS NOT SUPPORTED DUE TO PHYTO CONCERNS; REVISED USE PATTERN IS FOR A 30-DAY PHI OR POST HARVEST APPLIC

| EPA Default Residue Trials: |
2 5-2 10-3 11-2
|
| IR-4 Residue Trial Plan: |
2 5-2 10-2 11; 2 Red A trials one in reg 2 & one in Reg 5 needed for 2024 season. (No Decline Needed).
|
| Residue Protocol Use Pattern: |
USE THE ALION PRODUCT (1.67 LB AI/GAL OF INDAZIFLAM ACTIVE INGREDIENT); MAKE 1 PRE-EMERGENCE BROADCAST APPLIC OF 0.067 LB AI/A, IN MINIMUM 10 GPA, TO CLEAN SOIL AT 30 DAYS PRIOR TO FIRST COMMERCIAL ASPARAGUS SPEAR HARVEST; EACH APPLIC SHALL INCLUDE A LABELED RATE OF AN ADJUVANT

| Efficacy/Crop Safety (E/CS) Data Required: |
BAYER INDICATES THE NEED FOR E/CS TRIALS CONDUCTED AT A 2X SAFETY FACTOR AND FOR 3 CONSECUTIVE YEARS:06/20
|
| E/CS Research Comments: |
IN THE PERFORMANCE PROTOCOL FOR 2021 TRIALS: TESTING PRODUCT PERFORMANCE ON THE SAME PLOTS OVER A 3-YR PERIOD, WITH TRIALS CONDUCTED ON SOILS WITH UP TO 1% ORGANIC MATTER AND ON SOILS WITH >1% ORGANIC MATTER; TESTING 2 RATES OF ALION 1.67 SC (DIFFERENT RATES ON EACH SOIL TYPE), APPLIED BROADCAST PREEMERGENCE, 30 DAYS PRIOR TO FIRST COMMERCIAL SPEAR HARVEST, IN AT LEAST 10 GPA; SEE PROTOCOL FOR MORE APPLIC REQUIREMENTS; EVALUATE CROP INJURY, WEED CONTROL AND CROP YIELD; THE PERFORMANCE PROTOCOL FOR 2022 IS FOR YEAR 2 OF THE TRIALS STARTED IN 2021; THE 2023 PERFORMANCE PROTOCOL IS FOR YEAR 3 OF TRIALS ON THE SAME PLOTS STARTED IN 2021
