there is not right or wrong really but opinion on what is righr or better or good or bad.
Like Mr bush says, you need to figure out what your philosophy is.
Maybe you dont want to take chances and treat for mites, noseam, and foulbrood's
Maybe you want to be part of the treatment free club.
But, if you dont have a mentor, and a good one, how do you know if you have or dont have problems.
I would treat for mites, nosema, and foulbrood. I go to the doctor, I take medication, i have had vaccines. People here can scream all they want. Im not going to lose everything on a natural philosophy that i dont follow in my own life. I will however use organic methods as much as i can as long as they have real results, not just some trumped up wives tale.
Examples of organics are: oxalic acid, formic acid, thymol all for mites. And Honey be healthy made from organic oils in a drench for nosema. There is supposed to be some real studies which will have results in the coming year that will hopefully show that it can knock out nosema.
Brood diseases are another matter. For American foulbrood all you can do is shake n bake (shake bees on new hive of foundation and burn everything from old colony) or treat preventatively and hope you never see it. If you use tylan spring and fall, you should never see it.
