The Pest Management Regulatory Agency (PMRA) recently announced the approval of several URMULE registrations for Dual II Magnum Herbicide for management of weeds on celery, Asian radish (daikon, lo bok, mooli), parsnips and eggplant transplants in Canada. Dual II Magnum Herbicide was already labeled for use on a wide range of crops for weed control in Canada. 

The minor use project for celery was originally submitted by Ontario in 2010 and completed by AAFC-PMC. The minor use project for eggplant was sponsored by Ontario in 2014 and the projects for parsnip and Asian radish were sponsored by AAFC-PMC in 2012 all as a result of minor use priorities established by growers and extension personnel.
