Breakthrough in Biopesticides: Laminaria japonica Polysaccharides (Laminarin) Set for ICAMA Approval in China

Updated on Apr. 20th, 2026

The Institute for the Control of Agrochemicals, Ministry of Agriculture and Rural Affairs (ICAMA) recently released its list of proposed pesticide registrations. Featured prominently is the biopesticide product submitted by Laboratoires Goëmar, a French leader in seaweed-based solutions.

This notification confirms that the product has successfully navigated the rigorous technical review process by ICAMA’s expert committee. Once the public notice period concludes, the product will be officially granted a registration certificate, marking its formal entry into the Chinese agricultural market.

Technical Profile: How Laminarin Works as a Plant Immunity Inducer

Laminaria japonica polysaccharides, commonly known as Laminarin, function differently from traditional chemical fungicides.

Mechanism of Action: Its molecular structure mimics pathogen cell wall degradation products. When applied, it triggers Systemic Acquired Resistance (SAR) in plants.

Preventative Defense: Instead of killing pathogens directly, it "primes" the plant's own immune system to defend against future invasions.

Target Diseases: According to the ICAMA filing, the product is indicated for:

  • Strawberry Gray Mold (Botrytis cinerea)

  • Cucumber Powdery Mildew (Podosphaera xanthii)

These diseases are notorious for developing resistance to conventional chemicals, making biological alternatives like Laminarin essential for sustainable farming.

The Future of Biopesticides in China

The proposed approval of this product validates the technical and commercial feasibility of registering advanced biological control technologies in China. It provides a "green" alternative for growers facing strict residue limits and resistance issues.

Key Benefits for the Chinese Market

  1. Resistance Management: A novel mode of action to supplement traditional fungicide programs.

  2. Environmental Safety: Low toxicity and residue-free, aligning with China's "Green Development" agricultural policies.

  3. Market Diversification: Expands the availability of plant immunity inducers beyond traditional categories.
