In Canada, triticonazole is under re-evaluation by Health Canada’s Pest Management Regulatory Agency (PMRA). The PMRA re-evaluates registered pesticides to determine whether the use of these products continues to be acceptable in terms of value, human health and the environment according to current standards.
Triticonazole is a systemic fungicide registered for control or suppression diseases on cereals, corn and turf. As of 16 January 2019, 11 products containing triticonazole were registered in Canada including one technical grade active ingredient, two manufacturing concentrate and eight commercial class end use products.
Under the authority of section 16 of the Pest Control Products Act, the registrants of triticonazole were notified of the initiation of the re-evaluation of triticonazole. Following this, the registrants of triticonazole technical grade active ingredients in Canada indicated support of all uses included on the labels of end-use products in Canada.
The re-evaluation project plan below outlines the timeline, the anticipated areas of focus for the risk assessments, and the data requirements for the re-evaluation of triticonazole.
Re-evaluation Project Plan
Anticipated Re-evaluation Timeline
The re-evaluation of triticonazole is defined as a Category 1 as described in Regulatory Directive DIR2016-04, Management of Pesticides Re-evaluation Policy. However, because this re-evaluation was initiated prior to the publication of DIR2016-04, the proposed re-evaluation decision for triticonazole is anticipated to be published for consultation by July 2020. The re-evaluation timeline may be updated if, during the risk assessment, the PMRA identifies additional areas of focus that should be considered.
Human Health Risk Assessment
New assessments will be conducted for toxicology, dietary exposure, occupational exposure and residential exposure.
Environmental Risk Assessment
New assessments will be conducted for environmental fate, water modelling and environmental exposure.
The value of triticonazole will be considered. The viability of alternatives will be examined for certain uses if risks of concern requiring mitigation are identified.
The PMRA has identified the need for the technical registrants to provide data for triticonazole related to health and the environment. Available data have been submitted to the PMRA. A summary of the data call-in is found in the PMRA’s Public Registry. For a list of data categories that have been required, see Appendix I. In addition, information regarding the registered use pattern has been requested and received from the registrants, to inform the risk assessments.
PMRA documents can be found in the Pesticides section of Canada.ca. PMRA documents are also available through the Pest Management Information Service:
