The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Rootshield HC® Biological Fungicide for control of Botrytis (Botrytis cinerea) in Canada. Rootshield HC® Biological Fungicide was already labeled for management of diseases on a wide range of crops in Canada. This minor use proposal was submitted by Ministère de l’Agriculture, des Pêcheries as a result of minor use priorities established by growers and extension personnel.
The following is provided as an abbreviated, general outline only. Users should be making disease management decisions within a robust integrated disease management program and should consult the complete label before using Rootshield HC® Biological Fungicide
Rate (kg product/ha)
CG 13-07B, Bushberry
Botrytis (Botrytis cinerea)
Apply 10 grams per liter of water to foliage every 7-14 days depending upon disease pressure. Crop size, spray equipment and local practice will determine the volume of water needed. Apply prior to disease establishment, when conditions favour disease development. Apply enough volume to thoroughly cover foliage without runoff.
Do not apply or allow drift of Rootshield® HC Biological Fungicide to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers.
Follow all other precautions, restrictions, and directions for use on the Rootshield HC® Biological Fungicide label carefully.
