Trimmit Passes Muster

By WCTA Staff

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 Paclobutrazol Technical and Trimmit, containing the technical grade active ingredient paclobutrazol, for use on turfgrass on golf courses to slow the growth of turfgrass and suppress Poa annua.

Paclobutrazol is currently registered as a plant growth regulator for use on container grown ornamental bedding plants and plugs in greenhouses. For details, see Proposed Re-evaluation Decision PRVD2013-04, Paclobutrazol, and Re-evaluation Decision RVD2014-06, Paclobutrazol.

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.
