Hi all,
I have tried to eradicate Ascospheara apis, chalkbrood, in one of my colonies. After moving them onto new foundation, which they have drawn beautifully, and introducing a new strain queen which has just started to lay and giving them some emerging brood, I was very disappointed to find more chalkbrood.
I am now going to try bananas, as someone said on the forum, they produce ethanol. I found one study which suggested that it works as a fungicide, so here's hoping. The gas is heavier than air so it should logically fumigate the hive. The hive has OMF on poly national, but should I open entrance fully as the banana will also give off carbon dioxide? How long should I leave the hive closed up? Now, off to buy a banana. Thanks all.
