Isabion Syngenta Uses: Amino Acid Bio-Stimulant & Flowers

Isabion is an internationally recognized amino acid and peptide-based plant bio-stimulant manufactured by Syngenta through controlled enzymatic hydrolysis of natural animal collagen. Formulated to enhance nutrient uptake, alleviate abiotic stress, and stimulate flowering and fruit development, it is widely utilized across high-value horticulture and cash crops.

Last reviewed: 10 November 2026

Active composition and enzymatic origin

Isabion contains 62.5% biological organic matter, including a balanced spectrum of free L-amino acids (such as glycine, proline, and glutamic acid) and short-chain peptides. Because it is produced via enzymatic hydrolysis rather than harsh acid digestion, the biological L-conformation of amino acids is preserved intact, allowing immediate cellular absorption by plant leaves and roots.

  • Free L-amino acids: Preformed organic molecules that plants assimilate directly without expending metabolic energy.
  • Proline enrichment: Protects plant cell membranes and chlorophyll from drought and heat stress.
  • Natural chelation: Complexes with micro-nutrients in spray tanks, enhancing mineral absorption through leaf cuticles.

Key applications across commercial crops

  • Vegetables (tomato, chili, capsicum): Sprayed at flowering and early fruit set to prevent flower shedding and promote uniform fruit sizing.
  • Grapes and pomegranate: Enhances berry elongation, reduces fruit cracking, and improves sugar accumulation (Brix).
  • Field crops (cotton, pulses): Alleviates drought and waterlogging stress, accelerating crop recovery following adverse weather.

Recommended dosage and application advice

Apply as a foliar spray at 2 ml to 2.5 ml per litre of water (400 to 500 ml per acre) during morning or late afternoon hours. It can also be applied through drip fertigation at 1 to 2 litres per acre. Avoid mixing with heavy copper fungicides or sulfur sprays.

Common questions

What is the biological source of Syngenta Isabion?

It is derived from natural animal collagen through gentle enzymatic hydrolysis, preserving active L-amino acids.

How does Isabion help crops recover from weather stress?

It supplies ready-to-use amino acids that restore cellular osmoprotection and protein synthesis without draining plant metabolic energy.

Can Isabion be applied via drip fertigation?

Yes, it can be applied both as a foliar spray and through drip fertigation to stimulate root development and nutrient uptake.
