Dual Active Chemistry and Mitochondrial-Cell Wall Targets
Zampro synergizes Ametoctradin (a triazolopyrimidine respiratory inhibitor) with Dimethomorph (a cinnamic acid cell wall disruptor).
Ametoctradin inhibits mitochondrial Complex III at the Qo site in oomycete pathogens, shutting down energy synthesis and arresting zoospore release within seconds.
Dimethomorph translocates systemically to inhibit cellulose and phospholipid synthesis, rupturing fungal cell walls during mycelial growth.
- Ametoctradin (27%): Powerful respiratory inhibitor delivering rapid zoospore burst and protective wax binding
- Dimethomorph (20.27%): Systemic cell wall disruptor offering curative and anti-sporulant activity
- Anti-resistance design: Combining two entirely distinct modes of action protects against fungicide resistance
Target Crop Diseases and Approved Registrations
Zampro is registered across grapes, potatoes, tomatoes, and cucurbit vegetables for managing high-threat water-mold epidemics.
It is deployed preventively ahead of rainy weather or humid conditions favorable for fungal spore dispersion.
- Grapes: Unmatched control of downy mildew (Plasmopara viticola) on leaves, shoots, and fruit clusters
- Potato and tomato: Controls late blight (Phytophthora infestans) with excellent foliage and tuber protection
- Cucurbits: Prevents downy mildew (Pseudoperonospora cubensis) in cucumber, melon, and gherkin crops
Spraying Instructions, Rainfastness, and Safety
Dilute the suspension concentrate in clean water with continuous agitation and apply using fine mist sprayers.
Ametoctradin binds rapidly to plant cuticular waxes, providing exceptional rainfastness within one to two hours of application.
Observe recommended pre-harvest intervals and wear personal protective equipment during mixing.
- Preventive application: Apply ahead of rainfall or humid overcast weather for maximum efficacy
- Canopy penetration: Ensure thorough coverage of lower leaf surfaces where downy mildew sporulation occurs
- Personal protection: Wear chemical-resistant gloves, protective clothing, and eye goggles during preparation

Common questions
What chemicals are in BASF Zampro fungicide?
Zampro contains Ametoctradin 27% + Dimethomorph 20.27% SC in a suspension concentrate formulation.
What makes Zampro highly effective against downy mildew?
Ametoctradin causes zoospores to burst within seconds, while Dimethomorph systemically destroys fungal cell walls inside the leaf.
Does Zampro have rainfast properties?
Yes, Ametoctradin binds firmly to the plant wax layer, providing excellent rainfastness within 1 to 2 hours of application.
