Phosphite (H₂PO₃⁻), a reduced form of phosphate, is a biostimulant that enhances plant development and improves crop stress tolerance. Recent studies have shown that foliar application of phosphite promotes root biomass and nutrient uptake efficiency, particularly in wheat.
Boosting Root Architecture
Non-invasive 3D X-ray imaging of root systems directly in the soil has revealed that phosphite significantly enhances root architecture, leading to improved root mass. This contributes to greater nutrient and water absorption capacity, especially important in wheat cultivation under stress conditions.

Enhancing Nutrient Use Efficiency
Biochemical and physiological analyses have shown that phosphite increases the activity of nitrate reductase (NR), improves photosynthesis, and boosts stomatal conductance. This means better nitrogen and carbon assimilation, vital for plant productivity.

Improving Abiotic Stress Tolerance
Under nutrient deficiency, drought, or heat stress, phosphite-treated wheat showed improved photosynthetic efficiency and more stable PSII systems. This suggests phosphite helps plants better tolerate adverse environmental conditions.
🌿 Featured Product: FOSFOGUARD from Bimco International
FOSFOGUARD is a systemic potassium phosphonate (KH₂PO₃) compound that functions both as a fungicide and a biostimulant. It strengthens plant immunity, disrupts pathogenic fungi, and acts as a foliar fertilizer enriched with phosphorus and potassium.
It also promotes beneficial soil fungi and enhances nutrient uptake. FOSFOGUARD supports healthier root systems and boosts natural plant resistance against diseases and stress.
Recommended Dose:
200–300 ml per 100 liters of water (0.20–0.30%), applied every 7–10 days in 2–3 treatments.
❓ Frequently Asked Questions
Q1: What is phosphite and how does it differ from phosphate?
A: Phosphite is a reduced form of phosphate that acts as a plant biostimulant, while phosphate is an oxidized form primarily used as a traditional nutrient source in fertilizers.
Q2: How does phosphite improve stress tolerance in wheat?
A: It enhances root growth and boosts nitrate reductase activity and photosynthesis, helping the plant absorb nitrogen and carbon more efficiently under stress conditions.
Q3: What makes FOSFOGUARD effective?
A: Its systemic action and dual benefit—as a pathogen control agent and nutrient source—make it ideal for enhancing plant defenses and root health.
