Chemical profile and bidirectional translocation
- Phosphonate fungicide: Active ingredient Fosetyl-Aluminium at 80% concentration (FRAC Group P07 / unknown multi-site).
- True systemic movement: Unlike conventional fungicides that move only upward, Aliette travels bidirectionally: acropetally (upward via xylem) and basipetally (downward via phloem) into root systems.
- Dual mode of action: Directly inhibits fungal spore germination and penetration, while stimulating the host plant's internal synthesis of phytoalexins and defensive PR proteins (Systemic Acquired Resistance).
- Root and crown protection: Foliar sprays translocate downward to protect subterranean roots against soil-borne damping-off and root rots.
CIBRC approved target crops and diseases
Approved in Indian agriculture for managing Downy mildew in grapes; Damping-off and Phytophthora root rot in vegetable nurseries; Gummosis and collar rot (Phytophthora nicotianae) in citrus orchards; and Blister blight in cardamom and plantation crops. Used as a foliar spray, root drench, or tree trunk collar paste.
Mixing precautions, application and safety
- Do NOT tank-mix Aliette with copper fungicides or foliar nitrogenous fertilizers, as it can cause severe phytotoxic leaf scorching.
- Maintain neutral spray tank water pH; avoid highly alkaline water sources.
- Observe the mandatory Pre-Harvest Interval (PHI) specified on the product packaging before harvesting produce.
- Wear protective gloves, eye goggles, and a face mask during chemical handling.

Common questions
What is the active chemical ingredient in Aliette?
Aliette contains Fosetyl-Aluminium at 80% concentration formulated as a Wettable Powder (80% WP).
What makes Aliette's systemic movement unique among fungicides?
It is a true two-way systemic fungicide that moves both upward via xylem and downward via phloem into the plant root system.
Can Aliette be mixed with copper fungicides in the spray tank?
No. Tank-mixing Aliette with copper compounds or foliar fertilizers causes chemical incompatibility and severe crop phytotoxicity.
