New Syngenta fungicide protects against early blight

January 19, 2021  By Potatoes in Canada

Syngenta Canada recently announced three additions to their Miravis fungicide lineup, including one for potatoes and specialty crops.

Previously registered in several vegetable crops, Miravis Duo can now help potato growers safeguard quality and yield against early blight, in addition to several other costly diseases. Adepidyn is the main fungicidal active ingredient in Miravis Duo, working with difenoconazole (Group 3), which provides an added layer of protection and built-in resistance management.

Depending on their geography, potato growers can expect to make multiple in-season applications of a fungicide specifically targeting early blight. With every application of Miravis Duo, growers can also control brown spot while protecting against Botrytis and white mould. Ongoing changes to the use pattern of multi-site fungicides also means a shift from traditional foliar disease management. Miravis Duo’s broad-spectrum activity helps fill this gap and is the only non-chlorothalonil fungicide on the potato market offering activity against Botrytis.


In addition to potatoes, Miravis Duo is now registered in bulb, root and Brassica vegetables, along with ginseng and stone fruits.

The other two Miravis fungicides – Prime and Bold – are for use on an expanded range of horticultural crops and for Sclerotinia stem rot management in canola, respectively.
