Summary

Amended Proposed Re-evaluation Decision

The purpose of Re-evaluation Note REV2016-06, Chlorothalonil - Amendment to the Proposed Re-evaluation Decision is to notify registrants, pesticide regulatory officials and the Canadian public that Health Canada's Pest Management Regulatory Agency (PMRA) has amended its Proposed Re-evaluation Decision for chlorothalonil, PRVD2011-14.

Following the publication of PRVD2011-14, Chlorothalonil,the PMRA has revised the occupational and residential risk assessments with more information relevant to the potential effects of chlorothalonil on human health, particularly via dermal exposure. All other components of the proposed re-evaluation decision for chlorothalonil remain as originally described in PRVD2011-14.

Based on the revised occupational and residential risk assessments for chlorothalonil, the PMRA has determined that under the revised conditions of use, some agricultural uses of chlorothalonil do not present unacceptable risks to human health. These uses include asparagus, carrot, celery (seedbeds only), cucurbits, ginseng, mushroom, parsnip, potato, strawberry, tomato, turf (for control of snow mould only). As a condition of continued registration of these uses, new risk-reduction measures are proposed to be included on the labels of pest control products containing chlorothalonil.

Based on the human health risk assessment, the PMRA is proposing to cancel the following uses of chlorothalonil:

  • Agricultural uses: blueberry, highbush; blueberry, lowbush; celery, field; cherry (sweet and sour); chickpea; Cole crops; conifers (outdoor and nursery beds); corn, sweet; cranberry; evening primrose; lentil; nectarine; onion (dry and green); ornamentals (greenhouse and outdoor); pea, dry; peach; wheat; and turf (except for control of snow mould);
  • Material preservative use: paint.

Next Steps

This amended proposed re-evaluation decision is a consultation document. The PMRA is inviting stakeholders to submit comments on Re-evaluation Note REV2016-06, Chlorothalonil - Amendment to the Proposed Re-evaluation Decision, as well as detailed proposals to further refine the risk assessment and mitigate risks. The PMRA will accept comments and proposals for a period of 60 days from the date of publication of Re-evaluation Note REV2016-06, Chlorothalonil - Amendment to the Proposed Re-evaluation Decision. Please forward all comments to Publications.

Before making a final re-evaluation decision on chlorothalonil, the PMRA will consider all comments received in response to the previously published Proposed Re-evaluation Decision, along with any comments or proposals submitted in response to this amended proposed re-evaluation decision. A science-based approach will be applied in making a final decision on chlorothalonil. The PMRA will then publish the Re-evaluation Decision that will include the decision and the reasons for it, a summary of the comments and proposals received on both this document and PRVD2011-14, and the PMRA's response to these comments and/or proposals.

If no proposals to refine the risk assessment are received, or if those received are inadequate, then the PMRA will proceed to finalize the re-evaluation decision to cancel the chlorothalonil uses specified in this document.
