By: J. Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Rootshield WP® and Rootshield HC® Biological Fungicide for management of diseases on greenhouse vegetable transplants, ginseng, greenhouse and field fruiting vegetables, cucurbit vegetables and greenhouse ornamentals in Canada. Rootshield WP® and Rootshield HC® Biological Fungicide were already labeled for management of diseases on some greenhouse vegetables, ornamentals, strawberries and as a bean seed treatment in Canada.

These minor use projects were submitted in 2012 as a result of minor use priorities established by growers and extension personnel in Canada.  Management of these diseases with effective, reduced risk products is a priority of producers and buyers alike.

The minor use label expansion for Rootshield WP® and Rootshield HC® Biological Fungicideis a helpful step towards developing an improved pest management toolkit for greenhouse vegetable transplants, ginseng, greenhouse and field fruiting vegetables, cucurbit vegetables and greenhouse ornamentals in Canada. The following is provided as an abbreviated, general outline only. Users should consult the complete label before using Rootshield WP® or Rootshield HC® Biological Fungicide.
