--------------begin----
Note to CAPCO C94-05 will be revoked on March 2, 2011.

As Note to CAPCO C94-05 is limited in scope to applications of 65% formic acid solution in water, this regulatory decision is limited to products which are only formulated with formic acid and water, with a final application concentration of 65% formic acid in water.

As an interim measure, if submissions for registration of 65% liquid formic acid are received by March 2, 2011, use of 65% liquid formic acid according to the proposed label(s) may be permitted if the use directions raise no concerns until the completion of the full review of these submissions.

Any uses of 65% liquid formic acid which are not covered by the label(s) proposed for registration will not be permitted after March 2, 2011.
Proposed label application methods can be generic (for example, application rate, method, frequency, and timing) rather than specific (for example, directions limited to a specific applicator device).

As Note to CAPCO C94-05 specifically prohibits applications of formic acid during honey flow, applications of formic acid while honey supers are present on the hive are not permitted under this interim measure. Full evaluation and registration of use during honey flow is required for this use to be permitted.

Should no application for the registration of 65% liquid formic acid be submitted to the PMRA by March 2, 2011, all unregistered uses of formic acid will not be permitted as of that date.

It is not clear where to make "application for the registration" or if private applications are welcome

To buy JUST the formic is much less expensive than any of the strips or manufactured pads (~25%)
This may well be a factor
