Minor Use Label Expansion Granted for Scholar® 230SC Fungicide for Control of Post-Harvest White Mold on Carrots

J. Chaput, OMAF/MRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion for SCHOLAR® 230SC fungicide (fludioxonil) for control of post-harvest white mold (Sclerotinia) on carrots during storage. Scholar® fungicide was already labeled for management of several diseases on a range of crops in Canada.

This minor use submission was sponsored by the Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) in 2008 in response to minor use priorities identified by carrot producers in Canada. This was also the subject of several repeat emergency use submissions and registrations in several provinces over the past few years.

Access to post-harvest white mold management tools is a priority for carrot producers and the label expansion of Scholar® fungicide will provide producers with an helpful disease management tool. The following is provided as a general, abbreviated outline only. Users should consult the complete label before using Scholar® fungicide.

Scholar® fungicide can be applied as a post-harvest dip or drench immediately before storage at a rate of 496 mL product per 378 L water. This can treat up to 90,000 kg of carrots. Dip for 30 seconds and allow carrots to drain. One application per year is permitted. Do not allow rinsate to enter public water systems or aquatic habitats.


Scholar® fungicide should be used in an integrated pest management program and in rotation with other management strategies. Do not contaminate aquatic habitats when cleaning and rinsing spray equipment or containers. Follow all other precautions and directions for use on the Scholar® fungicide label.

We also wish to acknowledge Syngenta Canada Inc. for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
