oddly enough the official name of one of the newer beekeeping folks here. young people who I think both had some interest in physics and math while in school. The problem with some of these things is an effective way to deliver the product to the exact bees that need to get the stuff/medication. This was the problem with the consulting work I did in regards to the development of RNA interphase remedy.... additionally the RNA was very unstable... basically meaning it degraded fairly quickly. Then in regards to AFB you have the additional problem of spores... much like the question of nosema c and fumidil... what good does it do you if you treat, treat, treat and when you halt treating the problem quickly shows right back up??
