A water-soluble chitosan oligosaccharide hydrochloride that primes the plant’s own immune system turning crops into active participants in their own protection.
01 — The Molecule
What Chitosan AG Is
A low-molecular-weight chitosan oligosaccharide hydrochloride — < 3,000 Da, 2–20 glucosamine units.
- Fully water-soluble clean dissolution, no nozzle clogging
- Rapidly absorbed via roots and leaves
- Tank-mix friendly with NPK, humic / fulvic, amino-acid biostimulants, Trichoderma, Bacillus

03 — In The Field
Benefits for broccoli & peas
- Stronger emergence & seedling vigor
- Lower root & foliar disease pressure
- Better abiotic stress resilience
- Supports yield & quality potential
How to use it in existing programs
Four entry points across the broccoli & pea calendar from seed to canopy designed to slot into the spray plans, fertigation lines and biocontrol stacks you already run.
| # | Method | Rate (% w/v) | Primary benefit |
|---|---|---|---|
| 01 | Seed treatment | 0.1 – 0.2 % | Early vigor + seed and seedling defense from day zero |
| 02 | Root drench | 0.2 % | Root-zone immunity + transplant establishment |
| 03 | Drip irrigation | 0.01 – 0.025 % | Low-dose continuous rhizosphere support |
| 04 | Foliar spray | 0.4 – 1.0 % | Leaf-level defense priming during disease pressure |
Formulation Note
A defense-eliciting co-input — not a fungicide replacement
Position Chitosan AG alongside conventional chemistry to help reduce fungicide and pesticide load and concentration over time.
“May partially replace selected applications where field trials, labels and local regulations support it.”
Before broad deployment
- Confirm tank-mix & formulation stability
- Verify water quality and target pH
- Validate crop safety on broccoli & peas
- Check local regulatory & label fit
