Consultation on spiropidion, Proposed Maximum Residue Limit PMRL2026-07
Current status: Open
Opened on 23 June 2026 and will close for consultation on 6 September 2026
Health Canada is consulting the public and seeking your feedback on proposed maximum residue limit (MRL) increases for the foliar uses of spiropidion on bell peppers, non-bell peppers, tomatoes (and its processed commodity tomato paste), cantaloupes, cucumbers, muskmelons, pumpkins, watermelons and winter squash grown in Canada.
Health Canada is also consulting the public and seeking your feedback on setting new MRLs on leafy vegetables (crop group 4-13, except watercress), Brussels sprouts, Brassica head and stem vegetable group (crop group 5-13, except Brussels sprouts), grapes (and its processed commodities wine and raisins), fruiting vegetables (crop group 8-09), cucurbit vegetables (crop group 9) and pome fruits (crop group 11-09) grown in Canada.
Health Canada is also consulting the public and seeking your feedback on setting new MRLs on tuberous and corm vegetables (crop subgroup 1C), citrus oil, oranges (crop subgroup 10A, revised), lemons/limes (crop subgroup 10B, revised), grapefruits (crop subgroup 10C, revised), small fruits vine climbing except fuzzy kiwifruit and grapes (crop subgroup 13-07F), and cottonseeds (crop subgroup 20C, revised) imported into Canada.
An MRL is the highest amount of a specific pesticide residue allowed on a particular food when a pesticide is used according to label directions.
The proposed MRL increases for spiropidion are being requested as a result of re-assessed field trial data on field-grown tomatoes, bell peppers, non-bell peppers and eggplants, and assessment of new data on greenhouse-grown tomatoes, bell peppers and non-bell peppers (for the new MRL on fruiting vegetables (crop group 8-09) and tomato paste); and re-assessed data on field-grown cucumbers, cantaloupes and summer squash, and assessment of new data on greenhouse-grown cucumbers (for the new MRL on cucurbit vegetables (crop group 9)).
The proposed new MRLs for spiropidion are being requested as a result of new or re-assessed field trial data on potatoes (for the MRL on tuberous and corm vegetables (crop subgroup 1C)); lettuce, spinach and mustard greens (for the MRL on leafy vegetables (crop group 4-13, except watercress)); broccoli, cabbage, cauliflower and Brussels sprouts (for the MRLs on Brassica head and stem vegetable group (crop group 5-13, except Brussels sprouts) and Brussels sprouts); oranges, lemons and grapefruits (for the MRLs on citrus oil, oranges (crop subgroup 10A, revised), lemons/limes (crop subgroup 10B, revised) and grapefruits (crop subgroup 10C, revised)); apples and pears (for the MRL on pome fruits (crop group 11-09)); grapes (for the MRLs on small fruits vine climbing except fuzzy kiwifruit (crop subgroup 13-07F), wine and raisins); and cotton (for the MRL on cottonseeds (crop subgroup 20C, revised)).
These proposed MRL changes allow these treated foods, or any processed foods derived from them, to be either grown and sold in Canada, or imported into Canada.
Spiropidion
- Spiropidion is an insecticide not currently registered for use in Canada, and as such there are no current associated Canadian labels or uses.
- Food commodities treated with spiropidion were first allowed for importation into Canada in 2023.
What is the proposed MRL decision
This consultation is on the proposed decision to accept the request to
- Increase the MRL for spiropidion from 0.8 parts per million (ppm) to 3.0 ppm on tomatoes (as part of the new MRL on fruiting vegetables (crop group 8-09));
- Increase the MRLs for spiropidion from 1.0 ppm to 3.0 ppm on bell peppers and non-bell peppers (as part of the new MRL on fruiting vegetables (crop group 8-09));
- Increase the MRL for spiropidion from 1.5 ppm to 3.0 ppm on tomato paste (as part of the new MRL on fruiting vegetables (crop group 8-09));
- Increase the MRL for spiropidion from 0.8 ppm to 1.5 ppm on cucumbers (as part of the new MRL on cucurbit vegetables (crop group 9));
- Increase the MRLs for spiropidion from 0.9 ppm to 1.5 ppm on cantaloupes, muskmelons, pumpkins, watermelons and winter squash (as part of the new MRL on cucurbit vegetables (crop group 9));
- Add new MRLs for spiropidion on tuberous and corm vegetables (crop subgroup 1C), leafy vegetables (crop group 4-13, except watercress), Brussels sprouts, Brassica head and stem vegetable group (crop group 5-13, except Brussels sprouts), citrus oil, oranges (crop subgroup 10A, revised), lemons/limes (crop subgroup 10B, revised), grapefruits (crop subgroup 10C, revised), pome fruits (crop group 11-09), small fruits vine climbing except fuzzy kiwifruit (crop subgroup 13-07F), wine, raisins and cottonseeds (crop subgroup 20C).
Health Canada conducted scientific evaluations to determine the potential impact on human health of the new spiropidion uses. The scientific evaluations show that the proposed new and revised MRLs for spiropidion would continue to meet Health Canada's requirements for the protection of human health.
