Product Introduction
Brown Algae Oligosaccharide is low-molecular-weight oligosaccharide extracted and degraded from brown seaweed. It acts as plant elicitor to trigger crop immune response, activates endogenous defense pathways and enhances plant tolerance against biotic and abiotic stress. It regulates plant growth rhythm, promotes root development and improves nutrient uptake efficiency. As a core bioactive raw material for agro-formulations, it helps crops resist adverse stress, improves flower and fruit retention and upgrades commodity quality for high-value planting.

Health Benefits & Values
Trigger Crop Endogenous Immune Response
Recognized by plant cell surface receptor CERK1, activates salicylic acid (SA)-dependent defense signaling and ABA-dependent stress tolerance pathways, inducing ROS accumulation and defense enzyme activities (SOD, POD, PPO, PAL, CAT), improving resistance against fungal and bacterial pathogens.
Enhance Multi-Dimensional Abiotic Stress Tolerance
Mitigates damage from drought, salinity, low temperature and high temperature, helping crops recover rapidly from stress.
Promote Root Development & Nutrient Absorption
Stimulates root hair proliferation, expands root absorption area and boosts uptake efficiency of mineral nutrients.
Regulate Reproductive Growth & Fruit Setting
Balances plant hormone levels, improves flower bud differentiation, reduces blossom and fruit drop and promotes uniform fruit development.
Improve Produce Quality & Postharvest Storability
Increases soluble solids and fruit firmness, optimizes fruit appearance and extends shelf life of harvested agricultural products.
Overdose Risk Awareness
High concentrations (≥0.75%) may inhibit crop growth; 1.00% concentration can cause osmotic stress and cell membrane damage. Overdose may temporarily delay growth but typically recovers within days. Follow recommended dosages strictly.
Core Value in Formulation Development
High-Activity Seaweed Bio-Stimulant Base Material
Low molecular weight for fast plant absorption, retains the unique elicitor activity.
Flexible Formula Matching
Brown Algae Oligosaccharide can be compounded with amino acids, polyglutamic acid, macro/medium/trace elements for diversified agro-product development.
Excellent Fertigation Adaptability
Fully water-soluble with low insoluble impurities, suitable for foliar spray, drip irrigation and root drench without nozzle clogging.
Wide Compatibility With Agro Inputs
Compatible with most water-soluble fertilizers and neutral agrochemicals, expands application scenarios of compound functional formulations.
Stable Bioactivity During Shelf Life
Consistent biological activity under proper storage, avoiding rapid degradation of seaweed oligosaccharide active ingredients.
End-Application Scenarios
Crop Stress Resistance & Immunity Boost (Core Track)
Applied to fruits, vegetables, and cash crops for crop defense activation.
Flower and Fruit Retention Management
Foliar spraying at budding and flowering stages for pollination and fruit uniformity improvement.
Seedling Cultivation & Transplant Stress Relief
Drench or spray at seedling phase to promote root growth and alleviate transplant shock after seedling transplanting.
Functional Agrochemical & Fertilizer Formulation Development
Serves as core seaweed bioactive raw material for manufacturing seaweed-based biostimulants and compound functional fertilizers.
High-Value Crop Quality Improvement
Widely used for orchards, berries and greenhouse vegetables to enhance fruit flavor, glossiness and commercial value.
Application Advantages and Market Positioning
Seaweed Oligosaccharide Biostimulant Positioning
Belongs to agricultural biological agent, focusing on immune elicitation and growth regulation.
Low-Molecular-Weight Rapid Absorption Advantage
Oligosaccharide fragments have higher bioactivity and are rapidly recognized by crops.
Dual Functions of Immune Activation & Growth Regulation
Simultaneously boosts crop disease resistance and coordinates vegetative and reproductive growth to achieve yield and quality improvement.
Wide Adaptability Across Crop Systems
Suitable for fruit trees, greenhouse vegetables, field crops and seedlings, compatible with modern precision fertigation and foliar application.
FAQ (Technical Q&A)
Q1: How does this product differ from common seaweed extracts?
A: Ordinary seaweed extract contains mixed macromolecular alginate and multiple nutrients. This product is degraded into low-molecular oligosaccharide fragments, with stronger elicitor activity to trigger crop immunity and stress resistance. It belongs to agricultural biological agent, not simple nutritional fertilizer.
Q2: What is the optimal application concentration and timing for foliar spray?
A: Recommended concentration is 0.05%–0.30%, with 0.20% showing optimal induced disease resistance. For field crops, apply 30g per mu (powder) or 60mL per mu (liquid) at nutritional growth stage, fruit swelling stage, or 3 days before stress events.
Q3: What are the symptoms of brown algae oligosaccharide overdose, and how to avoid it?
A: High concentrations (≥0.75%) may inhibit growth; 1.00% concentration can cause osmotic stress and cell membrane damage. Overdose may temporarily delay growth but typically recovers within days. Follow recommended dosages strictly.
Q4: What is the registration pathway for this products in China?
A: It can be registered either as a pesticide (plant immune elicitor) or as a fertilizer (organic water-soluble fertilizer / compound fertilizer containing ). Registration category depends on product positioning and claims. Verify the registration certificate before purchase.
Q5: Can it be tank-mixed with microbial inoculant fertilizer?
A: Alternate application or low-tank mixing is feasible. It can assist beneficial microbes to improve rhizosphere environment. Apply together for synergistic soil improvement.
Q6: What are the key quality indicators to check when sourcing this products?
A: Check oligosaccharide content (powder: ≥20%; liquid: ≥20g/L), water solubility, pH range, and compliance with GB 38400-2019 for heavy metal limits. For compound fertilizers, verify compliance with T/HSPP 0015-2024.
Q7: What are the storage requirements for this product?
A: Store sealed in a cool, dry, ventilated warehouse away from high temperature and strong sunlight to protect oligosaccharide bioactivity. Shelf life is typically 2 years under proper conditions.
Q8: What crops have shown the best response to this product application?
A: Field trials show strong responses on wheat, tobacco, tomato, cucumber, and fruit trees. It is particularly effective for induced disease resistance and abiotic stress tolerance at critical growth stages.
Q9: Can it be used in organic agriculture?
A: Yes, most grades are eligible for organic planting programs subject to local organic certification standards. Check with local certifiers for approval status.
Q10: What is the core market positioning?
A: As a type II seaweed-derived agricultural biological agent raw material, it delivers brown algae oligosaccharide elicitor for foliar feeding and fertigation. With the capacity to activate crop immunity and strengthen stress resistance, it acts as a premium seaweed bioactive base material for developing biostimulant and functional agro-formulation products.
