| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Good Fit; This use fits well in asparagus IPM because it would provide an additional tool during a critical harvest window, help manage resistant pigweed populations, and reduce reliance on repeated use of the same herbicide chemistries:06/26;

| Reasons for need: |
Annual broadleaf weeds, especially pigweed species. Primary: Pigweed species, including redroot pigweed and Powell amaranth. Pre-harvest weed control options in asparagus are very limited. Most growers rely on ALS inhibitors, microtubule inhibitors, and PSII inhibitors, but resistance to ALS- and PSII-inhibiting herbicides is widespread in pigweed species in the region. During harvest, many preemergence herbicides begin to break down, allowing pigweed and other broadleaf weeds to emerge. These escapes can interfere with harvest, reduce spear quality and marketability, and increase weed seed return to the field. Current technologies used: Growers currently rely on ALS inhibitors, microtubule inhibitors, and PSII inhibitors for pre-harvest weed control, along with limited POST options during harvest. These programs often break down during harvest, and ALS- and PSII-resistant pigweed populations make control of escapes difficult:06/26;
