Zampro fungicide brings new mode of action for downy mildew and late blight control

January 14, 2013  By BASF

January 14, 2013, Mississauga, ON – BASF Canada Inc. (BASF) has received regulatory approval for Zampro fungicide for the control of downy mildew and late blight in many key fruit and vegetable crops.

“Because Zampro contains two active ingredients with different modes of action, this new product is going to provide fruit and vegetable growers with many of the benefits they’ve been asking for – preventative and anti-sporulant control combined with contact, translaminar and systemic activity,” says Scott Hodgins, Technical Specialist for Horticultural Products with BASF Canada.

Zampro contains the active ingredients Ametoctradin, the first Group 45 fungicide registered anywhere in the world and dimethomorph.


Ametoctradin controls downy mildew and late blight by disrupting energy production inside the fungal cells. Interestingly, although Ametoctradin is very rapidly rainfast, it can redistribute on the plant surface when exposed to rainfall, irrigation or dew, effectively re-protecting the plant.

Dimethomorph, a Group 40 fungicide, adds systemic and translaminar control in the crop. It controls infection by preventing the disease from penetrating plant cells. The dimethomorph component of Zampro is also an anti-sporulant, allowing Zampro to stop the spread of disease from hot spots that may develop in the field or vineyard.

Zampro is registered for use on grapes, potatoes and hops as well as the complete cucurbit, brassica, bulb vegetable, fruiting vegetable and leafy vegetable crop groups.
