Active Chemistry and Dual Mode of Action Against Oomycetes
Acrobat Complete deploys two distinct biochemical modes of action to halt destructive water mold pathogens.
Key biochemical attributes:
- Dimethomorph (9% WG): A carboxylic acid amide (CAA) fungicide that disrupts cell wall cellulose and phospholipid biosynthesis in oomycete fungi, causing cell lysis.
- Mancozeb (60% WG): A dithiocarbamate multi-site contact protectant that inactivates vital fungal sulfhydryl enzymes on leaf surfaces.
- Translaminar systemic mobility: Dimethomorph penetrates leaf cuticles and redistributes translaminarly, protecting unexposed lower leaf surfaces and new growth.
- Built-in anti-resistance protection: Combining a single-site systemic active with a broad multi-site protectant minimizes the risk of pathogen resistance emergence.
Target Pathogens and Registered Crop Indications
Engineered specifically for oomycete disease control, Acrobat Complete protects crops prone to rapid blight epidemics.
Key disease control targets:
- Potato Late Blight (Phytophthora infestans): Halts rapid defoliation and tuber rot during cool, foggy, and humid winter seasons in northern and eastern potato belts.
- Grape Downy Mildew (Plasmopara viticola): Protects tender leaves, flower inflorescences, and developing berries from destructive downy sporulation.
- Tomato Late Blight and Buckeye Rot: Prevents foliar blighting, stem lesions, and fruit decay, securing marketable crop yields.
- Cucurbits Downy Mildew: Suppresses Pseudoperonospora cubensis in cucumbers, melons, and gourds, preserving photosynthetic leaf area.
Application Best Practices, WG Technology and Handling
Proper application timing and tank preparation deliver maximum disease defense.
Operational recommendations for growers:
- Preventive application window: Spray preventively when weather conditions favor oomycete disease development (high humidity, morning dew, and overcast skies).
- WG formulation advantages: Water-dispersible granules dissolve rapidly and evenly in water without dusting, improving operator safety during tank preparation.
- Rainfast adhesion: Forms a resilient protective barrier on waxy foliage once dry, resisting washoff from intermittent rain showers.
- Operator safety: Always wear nitrile gloves, protective eyewear, and a dust mask during preparation and spraying, observing label pre-harvest intervals.

Common questions
What is the active composition of Acrobat Complete fungicide?
Acrobat Complete contains Dimethomorph 9% + Mancozeb 60% formulated as water-dispersible granules (WG).
How does Acrobat Complete stop potato late blight?
Mancozeb creates a multi-site protective barrier preventing spore germination on leaf surfaces, while Dimethomorph penetrates plant tissues to dismantle oomycete cell walls.
In which crops is Acrobat Complete primarily applied?
It is primarily used in potatoes, grapes, tomatoes, and cucurbits to control late blight and downy mildew infections.
