Dual active synergy and multi-directional translocation
Profiler pairs two unique biochemical modes of action to manage oomycete infections from both exterior and interior pathways.
- Fluopicolide (FRAC Group 43): Disrupts the spectrin-like cytoskeleton of fungal cells, causing rapid delocalization and zoospore lysis.
- Fosetyl-Al (FRAC Group P07): Inhibits fungal sporulation directly while inducing systemic acquired resistance (SAR) within host plant tissues.
- True amphimobile translocation: Fosetyl-Al moves both upward (acropetally) in xylem and downward (basipetally) in phloem vessels.
- Protects actively expanding shoots and delicate developing grape bunches from systemic downy mildew infection.
Downy mildew management in commercial viticulture
Profiler is formulated specifically to handle high disease pressure periods in table and wine grape vineyards.
- Target pathogen: Downy mildew (Plasmopara viticola) affecting leaves, tendrils, and floral clusters.
- Application window: Apply preventatively during vegetative shoot flushes, pre-bloom, and berry set stages.
- Bunches and fruit finish: Does not cause berry russeting or harm the natural bloom on developing grape clusters.
- Rainfastness: Rapid absorption into foliage ensures durable protection even during intermittent monsoon showers.
Spraying guidelines, dosage, and resistance management
Apply Profiler at the first sign of weather conditions favouring downy mildew using calibrated tractor air-assisted sprayers or power mist blowers. To maintain long-term fungicidal efficacy, do not apply Profiler more than twice consecutively; alternate with alternative FRAC mode of action fungicides. Wear standard personal protective gear during application.

Common questions
What are the active chemical ingredients in Profiler fungicide?
Profiler contains Fluopicolide 4.44% and Fosetyl-Al 66.67% in a water-dispersible granule (WG) formulation.
How does Fosetyl-Al in Profiler protect grapevines?
Fosetyl-Al provides direct systemic protection while triggering the grapevine's natural plant defense mechanisms (systemic acquired resistance).
Which major crop disease is Profiler specifically registered for in India?
Profiler is specifically registered for controlling downy mildew (Plasmopara viticola) in grapes.
