Fertilizer-pesticides and how they are regulatedįertilizer-pesticides are combination products that are regulated jointly by the CFIA and the PMRA. General labelling requirements for fertilizers and supplements under the Fertilizers Act and Regulations which are also applicable to fertilizer-pesticides and supplement-pesticides are described in Trade Memorandum T-4-130. Safety standardsĪll fertilizers and supplements used in cannabis cultivation must adhere to the standards outlined in Trade memorandum T-4-93 with respect to the product's content, composition, contaminant levels and upper tolerances around the level of micronutrient(s) guaranteed on the label. The CFIA and the PMRA are working on developing processes to enable market access of dual property products. Some plant growth regulators can do both – for example auxins (a naturally occurring plant growth regulator) can kill a plant if applied in high amounts (herbicide) or promote plant growth at lower concentrations (supplement). In general terms, products that are intended to promote growth are regulated by the CFIA and products that inhibit growth (for example delay ripening) are regulated by the PMRA. Plant growth regulators are regulated either by the Canadian Food Inspection Agency (CFIA) or by Health Canada's Pest Management Regulatory Agency (PMRA), depending on the mode of action, use pattern and performance claims. Plant growth regulators are a subset of supplements that trigger specific growth responses in plants (for example, an increase in root growth, shoot development, initiating flowering, etc.). They include (but are not limited to) products such as microbial inoculants, signalling compounds, abiotic stress protectants, wetting agents and surfactants, humic and fulvic acids and composts. Supplements are substances other than fertilizers that are manufactured, sold, or represented to improve the physical condition of the soil or to aid plant growth or crop yield.

micronutrients: boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), and molybdenum (Mo), which are required in smaller amounts mostly to treat a nutrient deficiency.secondary nutrients: calcium (Ca), sulphur (S) and magnesium (Mg).major nutrients: nitrogen (N), phosphorous (P), and potassium (K).Fertilizersįertilizers refer to products that are manufactured, sold or represented for use as plant nutrients. The Fertilizers Act and Fertilizers Regulations define what fertilizers and supplements are. For further information please contact Cannabis Canada.

New regulatory requirements (as of October 26, 2020) What you need to knowįertilizers and supplements are essential in any cannabis cultivation system but need to be properly managed in order to garner their full benefits while ensuring production of a safe crop.įertilizers and supplements can represent a risk pathway for the introduction of chemical and microbial contamination in the consumable portions of the cannabis plant and particular care should be taken to follow directions for use prescribed on the label and to use products that are compliant with the Fertilizers Act and Regulations in order to reduce potential for contamination.Īdditional requirements for any additives used in the production of cannabis (including fertilizers and supplements) may be applicable under the Cannabis Regulations, which are administered by Health Canada's Controlled Substances and Cannabis Branch.
