Hi, Vladimir. Our American Bee Journal had an article by Dr Steve Liu
([log in to unmask]) on the use of Margosan (an extract of the neem tree)
for control of chalkbrood. I bought a quart and have played around with
feeding in sugar syrup according to his instructions. I have not determined
if it works or not yet. You should be able to contact him at the e-mail
address. Let me know what you find out. Thanks.
