PHOSTER — Concentrated Phosphite (PO3) Bio-stimulant
PHOSTER is a highly concentrated Phosphite (PO3) formulation designed to stimulate lateral root development and maintain a positive transpiration stream. Highly plant-available, PHOSTER provides significant advantages for growers aiming to produce nutritionally balanced, healthy, and high-yielding crops.
The Phosphite Advantage: Bio-stimulation vs. Nutrition
It is important to distinguish between Phosphites (PO3) and standard Phosphates (P2O5):
- Phosphates (P2O5): Essential macro-nutrients used for plant energy and structure.
- Phosphites (PO3): Smaller, highly mobile molecules that act as true bio-stimulants.
While Phosphite is not utilized directly as a food source, it triggers powerful physiological responses that enhance nutrient uptake, internal transport, and overall plant performance.
Key Benefits for Crop Performance
Enhanced Root Architecture:
Promotes active lateral root growth, allowing plants to explore a greater soil volume to access water and essential nutrients more effectively.
Nitrogen Efficiency:
Boosts the activity of the enzyme nitrate reductase. This helps the plant convert nitrate into amino acids and proteins more efficiently, reducing energy waste.
Natural Resilience:
Reduces overall plant stress, creating a more naturally resilient and nutritionally balanced crop that is less prone to pest and disease outbreaks.
Why Choose PHOSTER?
PHOSTER delivers a powerful performance boost with its highly concentrated, plant-available formula. It is specifically designed to maximize uptake and deliver visible results, making it the smart choice for growers seeking stronger growth and improved outcomes across a wide range of fruiting and flowering horticultural crops.
Build stronger roots. Improve nutrient efficiency. Grow with PHOSTER.
It is recommended to apply PHOSTER as part of an INM (Integrated Nutrition Management) strategy. Typical application rates are between 0.75 – 1.5 L/ha.

Callos
CALLOS utilises complexing technology which increases calcium uptake via the leaf with less risk of scorch, more commonly associated with calcium based foliar, or reacting with other salts found in solution or on the leaf surface. Meaning more is available for rapid uptake by the plant. This low nitrogen formulation also prevents weak and leggy growth at a time when plants need to be focusing on flower and fruit formation.

Triad
A perfect combination of essential plant micro elements designed to promote strong hard growth and build up a plant’s natural resilience to pest and disease. Powered by Flex complex nutrient uptake technology, nutrients are supplied as a complexed molecule consisting of amide nitrogen and carbon chains. Ensuring all elements are taken up evenly and rapidly, increased nutrient use efficiencies ensures that the nutrients applied get exactly to where they are needed most by the plant.
