Bidirectional Systemic Movement and Defense Induction
Fosetyl-Aluminium (80 percent WP) is distinguished by true ambimobile (bidirectional) translocation within plant vascular systems.
Whether applied as a foliar spray, soil drench, or trunk injection, it moves upward via xylem and downward via phloem to protect root tips and new shoots alike.
In addition to directly suppressing oomycete pathogens, it stimulates the crop's natural phytoalexin production, fortifying plant structural defenses.
- Bidirectional mobility: Translocates upward to new foliage and downward into root zones
- Host defense induction: Triggers systemic acquired resistance (SAR) and phytoalexin synthesis
- Target class: Specifically combats Oomycete fungal-like organisms including Phytophthora and Pythium
Target Crop Diseases and Application Methods
Fosetyl-Al 80 WP is recommended for critical horticultural, plantation, and vegetable crops vulnerable to water-mold infections.
It is deployed preventively during periods of heavy humidity, high soil moisture, or seasonal monsoonal weather.
- Grapes: Effective prevention of downy mildew (Plasmopara viticola) on tender vines and clusters
- Citrus: Management of gummosis and root rot caused by Phytophthora species
- Vegetables and cardamom: Nursery drenching for damping-off and capsule rot protection
Application Guidelines and Tank Mix Precautions
Because Fosetyl-Al has an acidic pH profile in solution, it should not be mixed with copper fungicides or foliar fertilizers containing nitrogen or zinc.
Adhere strictly to label directions and ensure complete spray wetting of crop foliage or root zones during application.
- Incompatibility warning: Never tank mix with copper compounds or inorganic foliar nutrient mixtures
- Application timing: Apply preventively before disease establishment for maximum systemic efficacy
- Personal protection: Wear standard protective rubber gloves, mask, and eye goggles during mixing

Common questions
What makes Fosetyl-Al unique compared to ordinary systemic fungicides?
Fosetyl-Al features bidirectional mobility, moving both upward in xylem and downward in phloem to protect both roots and foliage.
Can Fosetyl-Al 80 WP be mixed with Copper Oxychloride?
No, Fosetyl-Al should not be mixed with copper fungicides because the acidic solution causes severe chemical incompatibility and phytotoxicity.
Which major disease does Fosetyl-Al control in grapes?
It provides exceptional systemic protection against downy mildew in grapevine canopies and fruit bunches.
