Product Introduction
Oligosaccharins Technical is a bio-derived agrochemical fungicide raw material, specially developed for formulators to manufacture finished pesticide formulations. It is enzymatically degraded from chitin raw material, featuring low molecular weight and excellent water solubility. Unlike pharmaceutical-grade oligosaccharide materials for health supplement, this agricultural technical works mainly by triggering crop systemic acquired resistance and interfering pathogen reproduction. It delivers preventive activity against fungal, bacterial and viral diseases, and can be processed into SL, WP and WDG for integrated crop disease management.

FAQ (Technical Q&A)
Q1: How should it be dissolved for formulation use?
A: Dissolve in dilute acidic aqueous solutions such as acetic acid, citric acid, or formic acid. It is insoluble in neutral water and alkaline solutions. For formulation, prepare an acidic stock solution first, then dilute with water to the target concentration.
Q2: What is the optimal pH range for formulation stability?
A: The formulation should be maintained at pH 3.0–6.0. Avoid strongly alkaline conditions, which may cause degradation or precipitation. For tank-mixing, test compatibility with alkaline pesticides before large-scale application.
Q3: Can it be processed into WDG and WP?
A: Yes. It can be processed into soluble liquid (SL), wettable powder (WP), water dispersible granule (WDG), and seed coating formulations. The low molecular weight and water solubility make it suitable for these dosage forms.
Q4: How does the degree of polymerization affect agricultural activity?
A: Low molecular weight fractions (DP 2–10) have better plant cell receptor binding capacity and are the core active segments for triggering crop immune response. Higher DP fractions may have reduced immune-inducing activity.
Q5: Can it be tank-mixed with copper-based fungicides?
A: Avoid mixing with strong alkaline agrochemicals. For copper preparations, a small pre-mix test is recommended. Chitosan can enhance copper ion uptake, so synergistic effects may be observed, but precipitation risk should be checked.
Q6: What is the recommended shelf life and storage condition?
A: Shelf life is 2 years when stored sealed in a cool, dry, shaded warehouse. Avoid strong alkaline environment and prolonged high temperature exposure. The product is stable to light and heat under normal storage conditions.
Q7: Does repeated field application trigger pathogen resistance?
A: The multi-pathway mode of plant immune induction and mild pathogen inhibition has low resistance risk. It is suitable for long-term rotation disease management programs and can be tank-mixed with chemical fungicides to delay resistance evolution.
Q8: How does it perform when combined with microbial fertilizers?
A: It is compatible with most microbial agents under proper pH conditions. It will not kill beneficial microbes, supporting integrated formulas combining disease prevention and soil improvement.
Q9: What is the key difference between Oligosaccharins Technical and pharmaceutical-grade chitosan oligosaccharide?
A: Pharmaceutical grade is refined for human health supplements with strict molecular specification for human metabolism. This agricultural technical is optimized for plant immune elicitation and pathogen inhibition, designed for crop protection formulation.
Q10: What is the recommended application timing for disease prevention?
A: Apply before disease onset or at the early symptom stage. For viral diseases, apply at the seedling stage and repeat every 7–10 days. Spraying in mild temperature and low sunlight conditions helps ensure uniform coverage.
