| Reduced Risk Status: |
|
| IPM Compatibility: |
Per requestor: Good Fit with no comments:06/23
|
| Reasons for need: |
Annual weeds; probably loss of Dacthal and dire need for alternative herbicides for onion:06/23; NY/Dry bulb onions lack significant chemical tools for the management of emerged weeds (which are especially competitive in young onions). The addition of an active ingredient could enhance the diversity and flexibility of control programs:08/23

|
| PCR Use Pattern: |
Postemergence broadcast over 2-lf stage onions; 1 or 2 applications; (RTI-TBD, PHI-TBD, though PHI will be variable since application is targeted to crop stage.

|
| Efficacy/Crop Safety (E/CS) Data Required: |
MFG is concerned with efficacy and phytotoxicity and requires at least 6 E/CS trials in the following states CA(1), PNW (2), S. TX (1), GA(1), NY (1):09/23
|
| E/CS Research Comments: |
PER THE 2024 PERFORMANCE PROTOCOL: TESTING ET HERBICIDE FOR PERFORMANCE AND CROP SAFETY ON DRY BULB ONION; TEST 5 RATES OF ET HERBICIDE/DEFOLIANT (0.0016, 0.0033, 0.0045, 0.0065, 0.0089 LB AI/A + ADJUVANT WITH EACH RATE [SEE ET LABEL FOR ADJUVANT]) VS A STANDARD; ALL TRTS ARE APPLIED BROADCAST EARLY POSTEMERGENCE (EPOST) OVER 2-LF CROP, IN AT LEAST 10 GPA; EVALUATE WEED CONTROL, CROP INJURY AND CROP YIELD
