Composition and physiological mode of action
Isabion provides readily available organic building blocks that save plant metabolic energy.
Key physiological actions:
- Active constituents: Balanced blend of free amino acids (glycine, proline, glutamic acid) and bioactive short-chain peptides.
- Energy conservation: Supplies pre-formed amino acids that plants assimilate directly, saving cellular energy normally spent on nitrogen reduction.
- Stress mitigation: Proline and glutamic acid act as cellular osmolytes, protecting cell membranes during drought, frost, and heat stress spells.
- Chelating action: Natural peptides chelate micronutrients in the spray tank, enhancing foliar absorption of applied trace minerals.
Target crops and strategic application stages
Biostimulants deliver maximum benefit when applied at critical physiological growth stages.
Recommended application windows:
- Vegetative establishment: Applied 20 to 30 days after transplanting to accelerate root development and branch tillering.
- Pre-flowering stage: Enhances pollen viability, improves flower retention, and prevents blossom drop.
- Fruit setting and enlargement: Promotes uniform cell division, increasing fruit size, luster, and marketable grading in grapes, pomegranate, tomato, and cotton.
- Follow product label directions regarding dilution rates for foliar spray and drip fertigation.
Compatibility, handling and application guidelines
Isabion is compatible with most standard fungicides and insecticides, but should not be mixed with strongly alkaline products (like Bordeaux mixture) or sulfur sprays. Apply as a fine foliar spray during calm morning hours to optimize leaf stomatal uptake.

Common questions
What is the primary composition of Isabion biostimulant?
It is composed of a natural mixture of free amino acids and short-chain peptides derived from animal protein hydrolysis.
How does Isabion help crops recover from weather stress?
The amino acids act as cellular protectants and osmolytes, helping crops maintain cellular water balance during drought, frost, or heat waves.
Can Isabion be applied through drip irrigation?
Yes, it can be applied both as a foliar spray and through drip fertigation to stimulate root elongation and soil nutrient uptake.
