Categories of Biopesticides and Related Products

For the purpose of the Pest Management Centre (PMC)'s work, biopesticides and other non-conventional pesticides are grouped into the following categories:

Microbials (see PMRA directive: DIR2001-02): A microorganism (bacteria, alga, fungus, protozoan, virus, mycoplasma or rickettsia and related organisms) and any associated metabolites to which the effects of pest control are attributed.

Semiochemicals (request directive: PRO2002-02 from the Pest Management Regulatory Agency): A semiochemical is a message-bearing substance produced by a plant or animal, or a functionally identical synthetic analogue of that substance, which evokes a behavioural response in individuals of the same or other species; some examples of semiochemicals are allomones, kairomones, pheromones, and synomones.

Other non-conventional Pest Control Products (see PMRA directive: DIR2012-01): Other non-conventional pesticides are substances not covered by the above categories which meet some or all of the following criteria: (i) low inherent toxicity to non-target organisms, (ii) not persistent in the environment, (iii) pesticidal action is not the result of toxicity to the organism, (iv) low likelihood of selecting for pest resistance, and (v) already widely available to the public for other uses, with a history of safe use under conditions posing equivalent potential for exposure to humans and the environment.
    Included in this category are common food items, extracts, preservatives or additives, plant extracts and oils, commodity chemicals that have a range of non-pesticidal uses, fertilizer or other plant growth supplements, commonly used in the agricultural sector, and inert materials
    Not included in this category are naturally occurring pesticides which are inherently toxic and as such would be reviewed by PMRA based on requirements and timelines for of a conventional pesticide.
