5. Key Benefits

  • Extreme biostimulant activity at very low dose
  • Outstanding tolerance to drought, heat, cold, salinity, and transplant shock
  • Dramatic improvement in fruit size, color, sugar content, and storage life
  • Strong induction of natural plant defense pathways
  • Significant increase in root mass and nutrient-use efficiency
  • Ideal for ultra-low-volume and aerial (drone) applications

6. Compatibility & Mixing

  • Highly compatible with most agrochemicals and fertilizers
  • Avoid direct mixing of concentrated product with calcium nitrate or pH >11 solutions
  • Jar test mandatory for new tank mixes

7. Storage & Shelf Life

  • Store between 5–35°C, protect from direct sunlight and freezing
  • Shelf life: 60 months from manufacturing date
  • Shake vigorously before use

8. Packaging

  • 250 ml, 500 ml, 1 L, 5 L, 20 L, 200 L, 1000 L IBC

9. Safety
