Under the authority of the Pest Control Products Act, all registered pesticides must be regularly re-evaluated by Health Canada’s Pest Management Regulatory Agency (PMRA) to ensure that they continue to meet current health and environmental safety standards and continue to have value. The re-evaluation considers data and information from pesticide manufacturers, published scientific reports and other regulatory agencies. The PMRA applies internationally accepted risk assessment methods as well as current risk management approaches and policies.
Aminoethoxyvinylglycine hydrochloride (also referred as aviglycine hydrochloride) is a plant growth regulator for use in apples. It is used as a harvest management tool to control fruit drop and delay maturity which allows growers to better schedule harvesting and avoid losses from dropped apples. Currently registered products containing aminoethoxyvinylglycine hydrochloride are listed in Appendix I.
This document presents the final regulatory decisionFootnote 1 for the re-evaluation of aminoethoxyvinylglycine hydrochloride including the required updated risk mitigation measures to protect the environment. All pest control products containing aminoethoxyvinylglycine hydrochloride that are registered in Canada are subject to this re-evaluation decision. This re-evaluation decision has gone through a 90-day consultation period as Proposed Re-evaluation Decision PRVD2017-14, Aminoethoxyvinylglycine Hydrochloride.Footnote 2
No comments were received during the consultation process. Therefore, this decision is consistent with the proposed re-evaluation decision stated in PRVD2017-14.
A reference list of all data used as the basis for the re-evaluation decision is included in PRVD2017-14.
Regulatory Decision for Aminoethoxyvinylglycine Hydrochloride
The PMRA has completed the re-evaluation for aminoethoxyvinylglycine hydrochloride. Under the authority of the Pest Control Products Act, the PMRA is granting continued registration of products containing aminoethoxyvinylglycine hydrochloride for sale and use in Canada. An evaluation of available scientific information found that the uses of aminoethoxyvinylglycine hydrochloride products do not present unacceptable risks to human health or the environment when used according to the conditions of registration, including amended label directions (Appendix II). No additional data are requested at this time.
Risk Mitigation Measures
Registered pesticide product labels include specific direction for use. Directions include risk mitigation measures to protect the environment and must be followed by law.Environment
- Updated buffer zone and label statements to protect non-target aquatic organisms.
To comply with this decision, the required mitigation measures must be implemented on all products labels sold by registrants no later than 24 months after the publication date of this decision document. Appendix I lists the pesticide products containing aminoethoxyvinylglycine hydrochloride that are registered under the authority of the Pest Control Products Act.
Any person may file a notice of objectionFootnote 3regarding this decision on aminoethoxyvinylglycine hydrochloride within 60 days from the date of publication of this Re-evaluation Decision. For more information regarding the basis for objecting (which must be based on scientific grounds), please refer to the Pesticides and Pest Management portion of the Canada.ca website (Request a Reconsideration of Decision) or contact the PMRA’s Pest Management Information Service.
