Key Benefits
- Stimulates root development and early seedling vigour
- Enhances natural plant defence mechanisms against abiotic stress (drought, salinity, heat, cold)
- Improves nutrient uptake efficiency and reduces fertiliser requirements
- Increases chlorophyll content, photosynthesis rate and overall crop quality
- Promotes uniform flowering, better fruit set and reduced fruit drop
- Improves shelf life and marketability of produce
- Fully biodegradable and non-toxic to humans, animals, beneficial insects and soil microorganisms
