Jim Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of minor use label expansion registrations for Cyclone and Lacto-san fungicide and bactericide for suppression of powdery mildew on field-grown cannabis and hemp in Canada. Cyclone and Lacto-san fungicide and bactericide were already labeled for use on a variety of crops in Canada for suppression of several diseases.  These are some of the first ever minor use registrations for ‘field-grown cannabis and hemp’ in Canada.

These minor use projects were submitted by Ontario as a result of minor use priorities established by growers and extension personnel.

The following is provided as an abbreviated, general outline only. Users should be making pest management decisions within a robust integrated pest management program and should consult the complete label before using Cyclone or Lacto-san fungicide and bactericide
