As a Beekeeper we are obliged to record any chemicals applied to one of our colonies, e.g. Apiguard, ApilifeVar or Oxalic Acid. Defra were kind enough to distribute a nicely laid out card.
To my mind this card is maybe suitable for beekeepers with a few hives, it is unmanageable for Beekeepers with many colonies.
I have laid out the required info in a word document, the key difference is that I have made space to allow the Beekeeper to enter a code against each product and reference that code in the application record.
This should make it simpler to manage for Beekeepers with more than a couple of hives.
