Product Overview
Wellyou Defender Potassium Phosphite is a high-efficiency systemic plant nutrition and protection solution based on phosphite technology. It delivers readily available phosphorus in the form of phosphite (P³⁺), combined with potassium and trace elements (Zn, B), to enhance plant resistance, nutrient uptake, and overall crop performance.
This product is designed for both nutritional support and plant defense activation, making it ideal for modern sustainable agriculture.
Guaranteed Analysis (w/v)
- Phosphorus (P₂O₅, as phosphite P³⁺): 520 g/L
- Potassium (K₂O): 340 g/L
- Zinc (Zn): 1 g/L
- Boron (B): 1 g/L
Key Features & Benefits
1. Fast Absorption & Systemic Movement
- Highly soluble and rapidly absorbed through leaves and roots
- Moves both upward and downward within the plant (xylem & phloem)
2. Dual Function: Nutrition + Protection
- Provides essential phosphorus and potassium nutrition
- Activates plant defense mechanisms (induced resistance)
3. Strong Disease Resistance Support
- Helps plants resist stress caused by:
- Downy mildew
- Phytophthora
- Pythium
- Enhances crop resilience under high disease pressure
4. Improves Nutrient Efficiency
- Enhances root activity and nutrient uptake
- Improves utilization of applied fertilizers
5. Enriched with Trace Elements
- Zinc (Zn): Supports enzyme activity and growth regulation
- Boron (B): Promotes flowering, fruit set, and cell wall formation
Mode of Action
Phosphite (P³⁺) acts differently from traditional phosphate:
- Directly participates in plant metabolic processes
- Stimulates plant immune response (phytoalexin production)
- Improves stress tolerance (biotic & abiotic)
