Complementary biochemical modes of action
Zampro brings together two potent active molecules from distinct chemical classes to overcome and prevent fungal resistance.
- Ametoctradin (FRAC Group 45): Inhibits mitochondrial respiration at complex III, stopping zoospore motility and release.
- Dimethomorph (FRAC Group 40): Disrupts cell wall phospholipid biosynthesis, causing lysis of growing fungal hyphae.
- Translaminar and locally systemic movement: Provides thorough protection across both upper and lower leaf surfaces.
- Strong preventative efficacy combined with early-stage post-infection curative control.
Target crops and disease management spectrum
Zampro is registered in India to safeguard high-value horticultural and vegetable crops against destructive water-mould infections.
- Grapes: Management of downy mildew (Plasmopara viticola) during vegetative shoot flushes and berry development.
- Potato: Prevention and control of late blight (Phytophthora infestans) to protect foliage and developing tubers.
- Tomato: Protection against tomato late blight affecting leaves, stems, and fruits.
- Excellent crop safety profile: Does not leave harmful russeting on developing grape clusters when applied at label rates.
Application timing, spray coverage, and resistance stewardship
Apply Zampro at the initial onset of disease-favourable conditions (high relative humidity and moderate temperatures). Ensure full foliar coverage using calibrated hollow cone nozzles. To maintain long-term chemical efficacy, do not apply more than two consecutive treatments; rotate with fungicides featuring alternative FRAC modes of action.

Common questions
What are the active chemical ingredients in Zampro fungicide?
Zampro contains Ametoctradin 27% and Dimethomorph 20.27% in a suspension concentrate (SC) formulation.
How does Ametoctradin prevent fungal infection?
Ametoctradin inhibits cellular respiration in fungal mitochondria, rapidly immobilizing zoospores and preventing plant tissue penetration.
Which diseases does Zampro primarily control?
Zampro is specifically formulated to control downy mildew in grapes and late blight in potato and tomato crops.
