Treatment Free Beekeeping - David Heaf

Descriere Treatment Free Beekeeping - David Heaf

\n \nSince varroa arrived in Europe and America in the 1980s, most beekeepers have found it necessary to treat their colonies with chemicals in order to avoid heavy colony losses. But a minority of beekeepers have managed to care for their colonies without the use of chemicals and have done so with not just tolerable colony losses, but with losses that are sometimes equal to or smaller than the losses of those beekeepers who treat with chemicals. \n \nWith the help of thirty examples of treatment-free beekeepers in Europe and America, including famous names in varroa-resistant bee breeding, this book documents the encouraging success and growing popularity of beekeeping without chemicals, and details the bee husbandries of the beekeepers presented.\n
