| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Good Fit; useful in controlling populations with established pesticide resistance application time is post-emergence and in our wild blueberry production system we would apply this during our non-blooming, non-cropping year therefore avoiding any off-target impacts to pollinators or beneficial insects:04/25;
|
| Reasons for need: |
Fine leaf sheep fescue (grass) Possibly broadleaf weeds as well such as goldenrod and red sorrel.Fewer herbicides are registered for use in Maine due to PFAS restrictions and weeds have become resistant to hexazinone, an herbicide relied on for many years:04/25; ME: Fine leaf sheep fescue produces a humid environment around its plants that can possibly allow improved overwintering of fungal pathogens & new group numbers are needed for better IPPM, weed control efficacy and resistance mgmt:09/25;

| Requesting State(s): |
ME:Calderwood, L*, Annis, S, Tooley, B ;
|
| PCR Use Pattern: |
Make one broadcast application after emergence of weeds and lowbush blueberries in the vegetative year (year 1 of 2 in fruit production). A labeled rate of a methylated seed oil or ammonium sulfate should be included in the spray mixture". An AI rate has not been specified by the requester but supporting data show a rate of 0.33 to 1.0 lb ai/a”. Requester updated 7/25/25 to Make one broadcast application at 0.089 to 0.178 lb ai/a prior to lowbush blueberry emergence in its non-fruiting year. A labeled rate of a methylated seed oil or ammonium sulfate should be included in the spray mixture:07/25/sb; Bayer supports a rate of 100-150 g ai/ha and that crop safety data is necessary prior to any residue work:08/25/sb;
