Why it matters
A more stress-tolerant crop loses less to weather and recovers faster, protecting yield and quality.
When it appears
Before and during heat/drought; and for recovery.
What drives it
- Reduced turgor and growth under water deficit
- Root function and water-use efficiency
- Osmotic adjustment in tissues
- Timing of stress relative to set and fill
How to manage it
- Irrigate steadily; build deep roots.
- Support with Grow Boost, Kelp Boost, and Armour Boost (silicon).
Recommended Vegalab program
Kelp Boost, Charge BioBoost and Root Boost — encapsulated biostimulant and rooting support to improve resilience and water-use efficiency under deficit.
Results you can mention: in citrus field trials, Sun Boost increased tree vigour and bloom; the firmness, cracking and stress products are positioned on cell-wall/calcium and biostimulant modes of action — keep this copy educational where specific-crop trial figures aren't yet available.
| Role | Product | Use |
|---|---|---|
| Abiotic stress | Grow Boost | Reduces stress from abiotic factors |
| Biostimulant | Kelp Boost | Stress & recovery support |
| Tissue strength | Armour Boost | Silicon for stress-resistant tissue |
Apply ahead of and during dry periods on the label interval; support rooting early in the season for deeper water access.
