The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Fontelis® Fungicide for suppression of Sclerotinia Stem Rot caused by Sclerotinia sclerotiorum on Crop Group 1B (Root Vegetables). Fontelis® Fungicide was already labeled for management of diseases on a wide range of crops in Canada. This minor use proposal was submitted by the Ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Québec 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 Fontelis® Fungicide.
|Crop(s)||Target||Rate (L of product / ha)||Application Information||PHI (days)|
|Crop Group 1B (Root Vegetables)|
celeriac (celery root);
radish, oriental (daikon);
|Suppression of Sclerotinia Stem Rot||1.25 – 1.75||Begin applications prior to disease development and continue on a 7- to 14-day interval. Within the stated ranges, use the highest rate and the shortest interval when conditions favour high disease pressure. Make no more than 2 sequential applications of Fontelis Fungicide before switching to a fungicide with a different mode of action. Maximum seasonal use rate is 4.5 L/ha.||0|
TOXIC to aquatic organisms. Observe buffer zones specified under DIRECTIONS FOR USE. To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water body. As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
Follow all other precautions, restrictions, and directions for use on the Fontelis® Fungicide label carefully.
