Mode of action & use

Mode of action

Releases copper ions that denature proteins and enzymes of fungi and bacteria at many sites.

Contact protectant: forms a protective deposit on plant surfaces and is not taken up into the plant.

Typical targets and crops

Fungal and bacterial diseases such as downy mildew, late blight, bacterial spots, blights and cankers in vegetables, citrus, grapes, coffee and fruit.

Resistance management · FRAC M

Multi-site contact fungicides carry a low resistance risk because they act at many sites in the fungal cell. They are valuable mixture partners for protecting single-site fungicides.

This is general information on the active ingredient. Registered crops, targets, rates and pre-harvest intervals follow the label approved in each market.
