Quantis Biostimulant: Composition, Abiotic Stress, and Foliar Use

Quantis is a specialized foliar biostimulant developed by Syngenta to protect field and horticultural crops against abiotic stress like heat, drought, and cold. Formulated with amino acids, short-chain peptides, and organic osmoprotectants, it activates the plant natural resilience mechanisms.

Last reviewed: 10 November 2026

Bio-Molecular Composition and Stress Alleviation

Quantis contains fermented organic carbon, free amino acids, peptides, potassium, and calcium compliant with the Fertilizer (Control) Order biostimulant regulations. It triggers antioxidant enzyme pathways (superoxide dismutase, catalase) to scavenge damaging reactive oxygen species produced during heat and water stress.

This bio-chemical buffering preserves cellular turgor and enzymatic functions under extreme weather conditions.

  • Mitigates thermal shock: Maintains membrane stability and photosynthesis when temperatures exceed normal physiological thresholds.
  • Flowering and fruit retention: Minimizes flower drop and fruit shedding caused by moisture stress during critical reproductive phases.
  • Osmotic balance: Bioavailable potassium and organic solutes maintain cell turgor pressure during dry spells.

Foliar Application Timing and Tank Compatibility

Quantis is most effective when applied preventatively 24 to 48 hours before an anticipated heat wave, dry spell, or during key phenological transitions (flowering, fruit set, grain filling).

Its high foliar bioavailability allows rapid leaf absorption without leaving phytotoxic surface residues.

  • Apply via uniform foliar spray during cool hours of the day using standard knapsack or tractor-mounted boom sprayers.
  • Compatible with most standard fungicides and insecticides; perform a jar test prior to wide-scale tank mixing.
  • Ensure thorough spray coverage on both upper and lower foliage for maximum peptide absorption.

Common questions

What is Syngenta Quantis used for in agriculture?

Quantis is a foliar biostimulant applied to protect crops from environmental stresses like excessive heat, cold spells, and drought periods.

How does Quantis help during flowering and fruit setting?

It provides bioavailable amino acids and osmoprotectants that stabilize cellular membranes and reduce flower abortion caused by abiotic stress.

Is Quantis classified as a chemical pesticide or a plant biostimulant?

Quantis is classified as a biostimulant under the Fertilizer Control Order (FCO) framework, containing organic nutritional components rather than synthetic toxic molecules.
