Good morning,
    i am looking for opinions on threshold levels at which varroa treatment should be instituted immediately and at what level one can wait until the end of honey flow.  I pulled honey yesterday and checked hives for varroa using the sugar roll.  Infection rate ranged from 0 to 3 percent.  I have some buckwheat in full bloom and would like to wait on pulling the remaining supers until the flow finishes up.  There is still much brood in the broodnests.  A search on treatment threshholds gives widely different levels at which to treat.  A Nebraska site suggests treating immediately at 3% while a Canadian site suggests at incidence levels below 10% I could wait.  Thanks for the help.
