Fungicide for celery leaf curl 

​Celery leaf curl

The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Switch fungicide for control of anthracnose (leaf curl) on celery in Canada. Switch fungicide was already labeled for use on a number of crops in Canada for control of several diseases.

This minor use project was submitted 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 pest management decisions within a robust integrated disease management program and should consult the complete label before using Switch fungicide.

Begin applications prior to or at the onset of disease and repeat applications on a 7-10 day interval if conditions remain favorable for disease development.

Do not make more than 2 applications per year.

May be applied on the day of harvest (0-day PHI).

Switch  fungicide is TOXIC to aquatic organisms. Fludioxonil is persistent and may carry over. It is recommended that any products containing fludioxonil not be used in areas treated with this product during the previous season. Do not permit Switch fungicide to contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers.

Follow all precautions and detailed directions for use on the Switch fungicide label carefully.
