Emergency extension for the use of Regalia Maxx biofungicide approved – to combat downey mildew outbreak

The federal Pest Management Regulatory Agency (PMRA) has approved a request by the OMAFRA’s provincial minor use coordinator for emergency use of Regalia Maxx on hops in Ontario, New Brunswick, Quebec and BC to combat downey mildew.

The request was made on behalf some organic hops growers in Quebec and B.C. regarding the need for additional organic products to control downy mildew this season, over concerns that the current 4 applications of copper currently permitted on hops would not be sufficient, due to the severity of the outbreak this in some parts of the country this year, given how severe symptoms are in some yards.

The emergency application to amend the registration of Regalia Maxx Biofungicide Liquid Concentrate (Reg. No. 30199) for the emergency suppression of downey mildew (Pseudoperonospora Humilia) on hops has been granted. Pursuant to section 18 of the Pest Control Product Regulations, the amendment is granted for a validity period beginning July 13, 2015 and ending July 12, 2016, subject to the following conditions. Label changes must be made according to the annotated supplemental label.

The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) must inform Marrone Bio Innovations should OMAFRA become aware of any incident that occurs as a result of the use of Regalia Maxx. For information on the Incident Reporting Program, please contact PMRA-Incident-ARLA@hc-sc.gc.ca.

OHGA agreed to cover a third of the cost of the emergency registration – on behalf if its members, in the event they need to add it to their IMP arsenal.
