Information on the Upcoming Amendment to API-Bioxal™ (Oxalic acid) in the USA

The EPA recently established an exemption from the requirement of a tolerance for residues of oxalic acid on honey and honeycomb. This regulation eliminates the need to establish a maximum permissible level on these commodities for residues of oxalic acid.

In more simple terms, this means three things:

  • Api-Bioxal can be applied year-round, even when honey supers are placed on the hives.
  • At this time, the number of product application in the year is not submitted to a limitation
  • Personal Protective Equipment requirements have been updated

This regulation is effective since February 23, 2021. Objections and requests were receivable before April 26, 2021. The label amendments expanding the in-hive use to year-round are still being finalized.

Important point: Api-Bioxal cannot be applied in hives when honey supers are on until the amended label or a supplemental label is provided on the product. USDA is pursuing a supplemental label to ensure that beekeepers can begin using this product legally when honey supers are on as soon as possible.
