HopGuard II now registered for use in Ontario

As of April 16th, 2020, the Ontario Pesticide Advisory Committee approved the use of HopGuard II for Ontario. This product, registered last year for Canada, required further review for use in Ontario. 

Now that the review process has been completed, HopGuard II can be used by beekeepers for the treatment of Varroa mites. Derived from hop compounds, this biopesticide is deemed an option for an organic management plan. It is best used when no brood is present, similar to oxalic acid.
