Just got done watching the U of Geogia 2 video "Year in the Life of an Apiary".


They only major head scratcher is Professor Delaplane's use of Fumadil and Teramycin in spring and fall. This seems to go against the advise I've received from you all. I tend to think it is not a good practice to routinely use antibiotics.

Thoughts? Comments?

You have to take what you read on this board remembering where it comes from. We are more likely to be conservative in the use of medications. We can also afford to lose a lot of bees and we do. Dr Delaplane and others are trying to build a system that it is possible for commercial beekeepers to use. THEY will use what they have to. I've heard of a few things that bother me enough that I don't want to eat their honey. Re: the antibiotics... they have already been using Tylosin for awhile. The rest of us have been waiting for it to become legal.
I have never had anything in my hives but O/A or FGMO.

> ...Fumadil and Teramycin in spring and fall...

I think that if you would ask Keith today,
he would admit that the tapes are slightly
outdated in regard to the position on
Teramycin use.

The current consensus is much more rational,
in that use of antibiotics is not recommended
unless one has a detectable problem.

But Fumadil is another thing. The consensus
remains unchanged. I don't think that the
whole nosema problem is thought about enough!

Nosema can cut a colony's growth and productivity
by 1/3 to 1/2. Unless you go look for the
disease, you may never see it.

It is the first thing I think of when I see a
few weak colonies in a yard of stronger colonies.

The "examine the mid-gut test" for Nosema has a
very high false negative rate. It only shows
the worst cases. Using a microscope, and looking
for the actual nosema paramecia is the only way to
get a good handle on the extent of the disease.

The good news is that resistance has never
cropped up, as it is an Antifungal, not an
antibiotic, so you COULD use it in both spring
and fall, but I don't know anyone who uses
it in fall.

The stuff is not cheap, but like a good queen,
it is an investment that pays direct dividends
in the form of bigger colonies and bigger crops.

Nothing else except Fumadil will cure a case
of nosema, and even the advocates of the
various alternative treatments have never
claimed that their favorite treatments have
any effect. To cure an intestinal fungus,
you need to feed syrup with an anti-fungal
to get it into the bees' digestive tracts
where it can work.
