Herve, Did anyone observe a disruption or delay in the bees' spring build-up? And, if yes, did the spring brood rearing resume normally at a later time? I recognize OA effectively kills varroa but does it negatively affect the bees' start to raise brood in the spring? Thanks, Waldemar Long Island, NY >At the last Qc beekeepers annual meeting, I heard at least one >important beekeeper reporting similar observation. [...] >From what I understand, low pH of OA solution would be >the main factor of varroacide action. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
