Two-Way Ambimobile Systemic Translocation and Direct Action
Fosetyl-Al (FRAC Group P07) belongs to the phosphonate chemical group. Unlike most systemic fungicides that move solely upward through xylem vessels, Aliette translocates in both xylem and phloem, moving downward from foliar sprays into deep subterranean root systems.
It works through dual mechanisms: directly inhibiting fungal spore germination and mycelial growth, while simultaneously stimulating host plant systemic acquired resistance (SAR) enzymes.
- Two-way systemic movement: Foliar sprays protect subterranean root systems against soil-borne root rot pathogens.
- Phytophthora specialist: Controls Phytophthora foot rot in black pepper, gummosis in citrus, and heart rot in pineapples.
- Downy mildew control: Suppresses downy mildew in grapevines and cucurbits.
- Induced plant immunity: Triggers natural phytoalexin production and cell wall thickening within host plant tissues.
Application Guidelines and Tank Mixing Precautions
Aliette can be applied via foliar spray, soil drenching, or nursery seedling root dips.
Growers must observe strict tank-mixing precautions because Fosetyl-Al is chemically incompatible with copper fungicides and foliar fertilizers.
- Do not mix with copper: Never tank-mix with copper-based fungicides; combining them causes extreme chemical phytotoxicity and leaf drop.
- Do not mix with foliar nitrogen: Avoid mixing directly with concentrated foliar nitrogen fertilizers in the same spray tank.
- Soil drenching: Drench tree basins for citrus gummosis and cardamom root rot to eradicate fungal mycelium in the rhizosphere.

Common questions
What is the active ingredient in Bayer Aliette?
Aliette contains Fosetyl-Al 80% WP (Fosetyl Aluminium), a systemic phosphonate fungicide.
What makes Aliette's systemic movement unique among fungicides?
It possesses true two-way ambimobile translocation, moving both upward via xylem and downward via phloem to protect roots from foliar sprays.
Can Aliette be mixed with copper fungicides?
No, never mix Aliette with copper fungicides; the combination causes severe chemical incompatibility and severe crop phytotoxicity.
