JINMAI® Seaweed Oligosaccharides is a highly concentrated plant biostimulant derived from premium deep-sea brown seaweed (Ascophyllum nodosum). Through advanced physical cell disruption combined with targeted enzymatic hydrolysis, large seaweed polysaccharides are converted into low-molecular-weight oligosaccharides with significantly enhanced biological activity and plant absorption efficiency.
Compared with conventional seaweed extracts, this refined formulation provides a more active and bioavailable source of natural plant stimulants. It contains a balanced spectrum of bioactive compounds including alginic acid, polyphenols, betaine, seaweed polysaccharides, mannitol, and naturally occurring plant growth regulators (PGRs). These compounds work synergistically to stimulate plant metabolism, improve nutrient assimilation, and strengthen the plant’s internal defense system.
By promoting root development, activating enzymatic pathways, and enhancing plant resilience to environmental stress, JINMAI® Seaweed Oligosaccharides supports healthier crop development and contributes to improved yield quality across a wide range of agricultural crops.

Key Features
Product Efficacy
⦁ Promote Crop Growth
Seaweed oligosaccharides activate key metabolic pathways within plants, increasing the production of endogenous hormones such as indole-3-acetic acid (IAA). This stimulation enhances cell division and elongation, resulting in faster vegetative growth.
Additionally, the product improves the activity of metabolic enzymes such as lipase, amylase, and protease, which play critical roles in nutrient transformation and energy utilization. As a result, crops show improved seed germination rates, stronger root systems, and more vigorous early-stage development.
⦁ Enhance Crop Resistance
Bioactive compounds in seaweed extracts help regulate abscisic acid (ABA) levels, improving plant tolerance to environmental stress conditions such as drought, salinity, and low temperatures.
Seaweed polysaccharides also form a natural protective layer around plant proteins and cell membranes, helping maintain structural stability under stress conditions. This mechanism delays premature aging of plant tissues and maintains photosynthetic activity during adverse conditions.
⦁ Inhibit Plant Pathogens
Seaweed-derived compounds act as natural elicitors that activate plant immune responses. They stimulate the synthesis of defense molecules such as phytoalexins and regulate salicylic acid signaling pathways involved in plant disease resistance.
Through these mechanisms, crops become better equipped to defend against common fungal, bacterial, and viral pathogens. Regular application can reduce infection rates and improve the overall health and resilience of the crop ecosystem.

FAQ
1. What are seaweed oligosaccharides and why are they beneficial for crops?
Seaweed oligosaccharides are low-molecular-weight carbohydrates derived from marine algae. Due to their small molecular structure, they are easily absorbed by plants and can stimulate physiological processes such as root growth, hormone regulation, and stress tolerance.
2. How is this product different from ordinary seaweed extract?
Traditional seaweed extracts often contain larger polysaccharide molecules that plants absorb slowly. JINMAI® Seaweed Oligosaccharides undergo enzymatic degradation to produce smaller molecules with higher biological activity, allowing plants to absorb and utilize them more efficiently.
3. Can seaweed oligosaccharides be used together with fertilizers or pesticides?
Yes. Seaweed biostimulants are generally compatible with most fertilizers and crop protection products. When mixed with fertilizers, they can enhance nutrient uptake efficiency; when combined with crop protection programs, they can improve plant recovery and resilience.
4. When is the best time to apply seaweed oligosaccharides?
The product is most effective during key crop growth stages such as seedling establishment, vegetative growth, flowering, and early fruit development. It is also beneficial before or after environmental stress events such as drought, frost, or transplanting.
5. Is this product suitable for organic or sustainable agriculture?
Because it is derived from natural marine seaweed and does not contain synthetic growth regulators, seaweed oligosaccharides are widely used in sustainable farming systems and environmentally friendly agricultural programs.
