Universities in USA say that there is no chemical treatment agaist chalkbrood.

Many stuffs have been advertised against chalkrood and it works mostly because mostly the disease goes away when warm summer weathers arrive.

"No treatment is presently available for control. In some cases, chalkbrood can be reduced by requeening colonies with a young queen."

Am sure I once read that Calcium Oxide was a treatment for chalkbrood.

Calcium Oxide is treated chalk. perhaps?

Calcium oxide is usually found as quicklime - used amongst, other things, to decompose slaughtered and buried animals such as for foot and mouth outbreaks in the past. Often spread on acidic land to raise the pH, but usually this has latterly been as 'slaked' or hydrated lime (quicklime reacted with just enough water to hydrate it).

Quicklime is produced in a lime kiln where the lumps of chalk (usually) are calcined (heated to drive off the carbon dioxide from the calcium carbonate). Quicklime is quite reactive and if mixed with the right amount of water will give out enough heat of reaction to raise the temperature to boiling pont of water (100 Celsius)

Not the sort of stuff for around bee colonies.

And hydrated lime is great as an annual chicken coop paint to prevent redmite amongst other nasties.

yes,it can be found in google. Reporting year is 2010.

Quite alkaline initially; back to calcium carbonate (chalk) in a few days, I suspect.
