Dunno, but our bee inspector used to get really wound up when I asked why they were not advising oxalic sublimation, around 15 yars ago. Especially when I insisted it worked OK for me.
That was in the days of bayvarol, apistan or apiguard only, along with a bit of IPM.
Japan professor generated hive sublimation on 1960's. But obviosly there were no beekeepers in Europe who understood Japanese language.
