>  Medivet, producing the same product using very similar methods

Saying these two are the same product is like comparing Pepsi & 7-up.  You 
virtually needed to be a pharmacist/chemist/something to get Fumadil-B to 
mix and even then..... That was why a bee supply company here pursued 
Medivet to make a replacement. The result not only mixed better and appeared 
to work, but it was substantially cheaper.  When beekeepers compared both, 
the bees never blocked at the syrup with Fumagilin-B like was sometimes the 
case with Fumidil-B.

> Now it appears that they have added advice to the label

That advice has been on our label for years. We have springs where you 
shouldn't or can't feed the bees until June (too late if you have a Nosema 
problem).  Spraying the top of the cluster a couple times has worked well.

>in advance of any data to support

I believe the data for Nosema apis exists. Second hand information tells me, 
what is being sot, is wheither or not this method will continue to work on 
Nosema ceranae.

And this isn't a problem????  Maybe this explains why in the days of package 
bees, when we fed a lot of spring syrup, we wondered at times if Fumidil-B 
was doing anything.  Perhaps your EPA was concerned that the product 
actually did what its label said it would.
