How to Reduce Heat Stress in Crops

Heat stress stalls photosynthesis, aborts flowers and fruit, and degrades quality across crops. As extreme-heat events become more common, holding set and finish through hot spells protects both yield and grade.

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

  • Photosynthesis shutdown at high temperatures
  • Flower and fruit abortion under heat
  • Transpiration demand and water stress
  • Oxidative stress in tissues

How to manage it

  1. Irrigate steadily; build deep roots.
  2. Support with Grow Boost, Kelp Boost, and Armour Boost (silicon).

Recommended Vegalab program

Kelp Boost and Charge BioBoost — encapsulated biostimulant actives that support osmotic balance and antioxidant defence to help crops hold function through heat.

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.

Apply ahead of and through forecast heat events on the label interval; combine with irrigation and, where used, shading.

Product claims, rates, and availability vary by jurisdiction; always follow the applicable label.

Frequently asked questions

Can a product stop heat damage?

It can’t remove the heat, but supporting osmotic balance and antioxidant defence helps crops hold set and quality through stress spells.
