If you've been following discussions about using OAE with cellulose pads in your hives please read the following from Vermont's State Apiculturist Brooke Decker:
Effective March 21, 2023 the Vermont Agency of Agriculture, Food and Markets has removed the Extended Release Oxalic Acid FIFRA 2(ee) interpretation notice from our website. This was done as a result of a determination by the US EPA on March 21, 2023 that this interpretation was not allowed under the provisions of FIFRA. As a result of this determination, the application of oxalic acid using glycerin treated cellulose pads is no longer considered allowable under the provisions of FIFRA 2(ee). A copy of the letter is available here:

All persons who apply pesticides must comply with all label provisions including directions for use, personal protective equipment, disposal instructions and environmental protection statements.
