Two new fungicide registrations!

That’s right!  As of today, flower growers have 2 new weapons against fungal diseases at their disposal. Heritage MAXX (azoxystrobin) and Medallion (fludioxonil) are now registered for use in outdoor and greenhouse ornamentals.

Impatiens showing signs of nutritional deficiency due to Pythium root rot infection.  Heritage MAXX is now available for Pythium control in greenhouse ornamentals.

Heritage (a Group 11 fungicide) is a systemic fungicide, and is appropriate for control of Pythium, Grey mould (aka Botrytis blight) and Rhizoctonia.  It can also be used for foliar diseases such as Powdery Mildew, Downy mildew, Rust, Anthracnose and Alternaria  Leaf Spots.  You can find the new label here: HeritageLABEL2016.

Medallion (a Group 12 fungicide) is a contact fungicide, and is appropriate for control of root rots such as Fusarium, Rhizoctonia, and Black Root Rot (Thielaviopsis) when applied as a drench.  It can be applied foliarly for Grey Mould, Anthracnose Leaf Spot and Rhizoctonia Stem Rot.  MedallionLABEL2016.

Alternaria on impatiens

Medallion fungicide is now available to Canadian ornamental growers to help control diseases like Alternaria leaf spot (shown here on impatiens).

Both are broad-spectrum fungicides that can be used curatively or prophylactically.

As with any chemical control product, make sure to read and follow the label carefully prior to use.

(Also, 1000 points each to the team that helped push these label expansions forward:Cary Gates, Flowers Canada; Jim Chaput, OMAFRA; Jennifer Llewellyn, OMAFRA and Graeme Murphy, formerly of OMAFRA).
