Herbicide Program for the 2021 Season

Annually VFM Ltd. prepares a detailed herbicide spray project plan that includes descriptions of the spray blocks and specific implementation plans for security, safety, and communications. MNRF's Sudbury District reviews/approves these plans and participates, to some extent, in their implementation. To read these plans click here.


VFM Ltd. has compiled an index map illustrating the location of this year's aerial application programs. Please refer to the project numbers on the index map to find the corresponding Block Map below.
