| IPM Compatibility: |
Per Requester: Good Fit; It has shown to be mostly safe for hives (particularly when alterative is loss of colonies due to mite infestation), application timing compatible with pest monitoring which is usually throughout the year depending on region, pesticide plays a significant role in an existing IPM program already and the beekeepers rely on amitraz as a part of their IPM and seems to be one of the most effective management approaches for varroa:06/25;
|
| Reasons for need: |
For management of Varroa mites in hives. Beekeepers are losing colonies at unprecedented rates and varroa mites are still one of the leading causes. Beekeepers have a very limited number of products/active ingredients at their disposal. Amitraz is still currently being used by many beekeepers as a management tool, but a higher concentration might be necessary at this point to achieve effectiveness while other possible novel treatments are being developed:06/25;

| Requesting State(s): |
CA:Nino, E* ;
|
| PCR Use Pattern: |
Make up to four applications per year of 6.25% v/v amitraz:oil impregnated shop towel, placed on to the top of hive frames between brood boxes. Leave the impregnated towel in place and do not disturb it for 42 days, then remove any remaining material. Do not apply during honey flow.

| Comments: |
Key Export Markets: Yes; Amitraz was produced and sold by Bayer in the US for crops, under Ovasyn Insecticide/ Miticide (EPA Reg 264–625) and Mitac W Insecticide (EPA Reg 264–636). Bayer submitted for cancellation of these uses approved in 2006. Off-label use of Bovitraz is illegal and the use is widespread. Beekeepers are now asking for an EPA approved use, for what they have been doing for decades (when the old Bayer products were available to farmers in the US). There is a legal use of Amitraz (impregnated plastic strips) for beehives, produced by Veto Pharma- called Apivar and new formulation called Apivar 2 (or Plus). These are not as useful to beekeepers due to high cost. Apivar resistance is also now apparently widespread in commercial bee operations in the US, according to a recent USDA-ARS report.
