• Fosetyl-Aluminium is one of the most powerful systemic fungicides used in agriculture. It is supplied as a water-dispersible powder with a WDG (Water-Dispersible Granule) formulation, typically at an 80% concentration.
• This fungicide is widely used to control diseases caused by oomycete fungi (Oomycetes) such as Phytophthora spp., Pythium spp., and Plasmopara spp.. It plays a key role in the prevention and treatment of woody diseases, root rot, downy mildew, collar rot, and other decay-related diseases.

Mode of Action

• Fosetyl-Aluminium is a compound consisting of an aluminum ion combined with three molecules of
• O-ethyl phosphonic acid. Due to its high solubility and polar structure, this ionic compound is readily absorbed through both leaves and roots and is systemically translocated throughout the plant.
• After absorption, Fosetyl-Aluminium is converted within the plant into phosphorous acid, which has strong fungicidal activity.
• This fungicide inhibits the fungal respiratory chain in the mitochondria and prevents spore germination and mycelial growth, thereby stopping the development of pathogenic fungi.
• In addition, it stimulates the plant’s natural defense system by increasing the production of phytoalexins (natural antimicrobial compounds), enhancing plant resistance to diseases.
• Fosetyl-Aluminium has bidirectional systemic movement (both upward to shoots and young leaves and downward to roots), providing complete and long-lasting protection for the plant.

Uses

• Collar and root rot (gummosis) in citrus and pistachio
• Downy mildew in grapes and vegetables
• Potato and tomato rot
• Fire blight in apple and pear
• Bacterial and fungal cankers in fruit trees
• Soil-borne fungal diseases and various rot diseases in agricultural and horticultural crops
• A truly systemic fungicide with bidirectional movement within the plant, providing a combined effect through direct action on fungi and stimulation of the plant’s defense mechanisms.
• Simultaneous control of fungi and bacteria that play a role in certain diseases.
• Reduces the need for contact pesticides and increases the overall efficiency of disease control.
• Easy application by foliar spraying or irrigation.
• Common application rate for foliar spraying: 300–500 g per 1,000 liters of water.
• Under severe conditions, soil drench/irrigation at an appropriate concentration is also used to control root diseases.
• The best time of application is before disease onset or at the early stages of symptom appearance.
• The interval between spraying cycles is usually 14 to 21 days.
• The pre-harvest interval (PHI) varies by crop, typically 7 to 21 days.
