Chemical class and unique cell wall mode of action
- Cinnamic acid amide class: Active ingredient Dimethomorph belongs to FRAC Group 40 (Cellulose Synthase Inhibitors).
- Cell wall lysis: Specifically inhibits the synthesis of glucan and cellulose in Oomycete cell walls, causing cell wall collapse and death during all stages of fungal reproduction.
- Anti-sporulant efficacy: Strongly suppresses sporangial formation and zoospore release, halting the epidemic secondary spread of disease in vineyards and potato fields.
- Translaminar mobility: Moves across leaf tissues to protect both upper and lower leaf surfaces from fungal colonization.
CIBRC approved target crops and diseases
Registered under CIBRC label directions for controlling Downy mildew (Plasmopara viticola) in grapes, and Late blight (Phytophthora infestans) in potato and tomato crops. In commercial viticulture and potato farming, applying Acrobat at the early appearance of oil spots or water-soaked lesions prevents widespread crop defoliation.
Application guidelines, dosage and resistance management
- Commonly tank-mixed or alternated with multi-site contact protectants like Mancozeb to broaden disease control and manage fungal resistance.
- Apply at recommended label dosages per acre; ensure complete foliage wetting using a calibrated knapsack or power sprayer.
- Observe the mandatory Pre-Harvest Interval (PHI) printed on the container label before harvest.
- Wear personal protective gear and avoid spraying during high wind conditions.

Common questions
What is the active chemical ingredient in Acrobat fungicide?
The active ingredient in Acrobat is Dimethomorph at 50% concentration formulated as a Wettable Powder (50% WP).
How does Acrobat control downy mildew in grapes?
It inhibits cellulose synthesis in fungal cell walls, causing pathogen lysis and preventing sporangia from spreading new infections.
Can Acrobat cure established late blight in potato fields?
Acrobat offers early curative and strong anti-sporulant action, but application at the initial appearance of symptoms yields the best control.
