| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Good Fit; Control of exotic annual grasses will allow for restoration of natural rangeland flora; with downstream implications on wildlife habitat, species diversity, and pollinator habitat; VERY GOOD FIT: SAME: WSR
|
| Reasons for need: |
Invasive annual grasses and broadleaf weeds to restore natural rangeland; Restore exotic annual grass invaded sites. The invasive annual grasses (Bromus tectorum, Ventenata dubia, Taeniatherum caput-medusae and others) compete directly with native perennial grasses, forbs and shrubs. They provide fire fuel resulting in more frequent wildfire and the diverse, deep rooted native range transitions to a monoculture of shallow rooted invasive annual grass:07/23

| PCR Use Pattern: |
Apply Rejuvra once at 7 fl oz/A as a broadcast application. Apply in fall before the first expected germination of annual grasses and within two months of the first expected precipitation. Apply only once a year.

| Comments: |
Camas (Camassia quamash) is a naturally occurring rangeland food plant that is sometimes harvested for human consumption. Mfg (ENVU) supports as "Researchable, Only Residue Data Needed", and a 22 month guideline study crop rotational data is available:08/23; EPA Green 12/23; Status changed to "complete w ongoing trials" 05/24/drs; although ENVU supports, BAYER, who holds the technical label, does not. Since a residue study was started, an alternative chemistry is being sought for Camas to move forward:09/24/sb;
