Canada to approve Nufarm's Anuew Plant Growth Regulator

Health Canada’s Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is proposing registration for the sale and use of Nufarm Prohexadione Calcium Technical Plant Growth Regulator and Anuew Plant Growth Regulator, containing the technical grade active ingredient prohexadione-calcium, for growth management of the following turfgrass species: Bentgrass, annual and perennial Poa annua, Kentucky bluegrass, perennial ryegrass, tall fescue and fine fescue, growing on golf courses, sod farms, sports fields, municipal sites and cemeteries.

Prohexadione-calcium is a plant growth regulator used for growth management of select turfgrass species. Prohexadione-calcium is currently registered for use on apple, cherry and strawberry.

Anuew Plant Growth Regulator, containing Prohexadione-calcium, is a plant growth regulator used for slowing vertical growth, reducing mowing frequency and enhancing colour and quality of select turfgrass species growing on golf courses, sod farms, sports fields, municipal sites and cemeteries.

Anuew Plant Growth Regulator will serve as an additional option for turfgrass growth management and align with an option that is presently available to users in the United States.

An evaluation of available scientific information found that, under the approved conditions of use, the health and environmental risks and the value of the pest control products are acceptable.

Before making a final registration decision on prohexadione-calcium and Anuew Plant Growth Regulator, Health Canada’s PMRA will consider any comments received from the public in response to PRD2022-05. Health Canada will accept written comments on this proposal before 17 April 2022.
