Oh Yes, those nasty chemicals in sugar.
Tell me Robo, beyond the vague article you posted on beet sugar on another forum, which even uses terminology like "possible" contaminates, why do you constantly bash others for using powdered sugar? Do you know what kind of sugar is being used? Is the poster asking about beet sugar?
I think those using such measures as powdered sugar should be appluaded for their efforts. It is a step in the right direction. Informing others of the "possible" contaminates, even if your articles backing your claims are vague and far reaching at best, would be a better approach. Perhaps organic or a better sugar can be used as compared to your "tainted" beet sugar you like to harp about constantly.
Bashing others and belittling them about being naive, when you openly encourage others to do such things like marking queens, is a bit naive in itself.
We can not get every chemical out of the food supply. I question the pureness of anything marketed. And yes, chemicals can be found in about every food source. But bashing those trying, moving away from standard treatments, and trying better approaches, should not be made to feel inadequate. I think ripping on someone keeping 99% of the chemicals out of the hive, due to that 1% still there, and lumping that person with everyone else becuase they are percieved as bad as those with far more chemicals in the hive, is a bit nitpicking. I know this whole "Sugar is bad" is a pet peeve of yours. Really sad to think that we need to slam everyone over it, when most assume a 5 pound of sugar off the supermarket shelf is somewhat safe. Probably much safer than that paint your plastering on the backs of your queens.
Your bees are probably dragging in more from down the street than the low levels in such items as store bought sugar.
bee-n-trees, if you want to get anal about sugar, you could always get organic sugar. I don't see the need. With the right equipment options, genetics, and management decisions (requeening and brood breaks), you can forego most standard treatments. I know many that use treatments spring and fall, and they still have high losses. That is not to say I suggest saving every hive. If nature culls out the weakest 10-20% every year, then you will be better off for it in the long run. Saving those hives that can not cope with mites, is not a stategy for my approach.
