I would say possibly, not absolutely, unless you are a scientist with empirical evidence. It seems to me you are running down commercial beekeeps with 'absolutes' also. How do you know if the chemical in harmful levels are these in nucs? Or even if they have or are susceptible to AFB?
I don't use chemicals in my hives but I don't run down others who do or blame them for problems that may not be their fault.
