Product Introduction
As a biogenic agricultural fungicide, Lentinan SL is derived from mushroom polysaccharide extracts. It triggers crop systemic acquired resistance to suppress pathogen infection rather than direct microbe killing. It activates plant immune pathways to reduce disease incidence caused by viruses and fungi. It acts as a finished formulation directly usable for foliar application, helping growers enhance crop self-defense capacity and stabilize yield under biotic stress.

Health Benefits & Values
Induce Crop Systemic Acquired Resistance
Activates plant endogenous immune response to build broad-spectrum defense against fungal and viral pathogens.
Suppress Pathogen Multiplication Inside Tissues
Restrains pathogen proliferation and lesion expansion by strengthening cell wall barrier of host crops.
Alleviate Biotic Stress & Stabilize Crop Yield
Reduces disease damage and mitigates yield loss when crops are under infection pressure.
Good Plant Safety & Low Environmental Impact
Biologically sourced active component, gentle to target crops with low residual risk for green planting.
Excellent Tank-Mix Compatibility
Compatible with most neutral/acidic agrochemicals, convenient for combined application in field programs.
Core Value in Formulation Development
Ready-to-Use Soluble Liquid Formulation
Lentinan SL is a finished soluble liquid product, no further grinding or formulation processing required for end users. Simplifies field mixing and application workflow.
Immune-Activating Mode Complements Traditional
Fungicides Functions via plant immune induction instead of direct biocidal action. It can be tank-mixed with conventional fungicides to expand control spectrum and slow resistance evolution.
Stable Liquid Physical Properties
Uniform liquid system with good water dilution performance, free of dust risk compared with powder formulations.
Wide Crop Adaptability
Suitable for vegetables, fruits, grains and cash crops, supporting integrated disease management for multiple planting scenarios.
Low Residue Profile Fits Green Agriculture
Natural polysaccharide active ingredient, aligning with low-residue and food-safe crop production requirements.
End-Application Scenarios
Fungal & Viral Disease Integrated Management (Core Track)
Applied on vegetables, tobacco, fruits and grains for control of mosaic virus, powdery mildew and other fungal-viral compound diseases.
Foliar Spraying for Immune Enhancement
Regular foliar application to activate crop immunity before disease onset, serving as preventive treatment.
Tank-Mix Partner for Conventional Fungicides
Combined with chemical fungicides to strengthen overall control effect and reduce single-agent selection pressure on pathogens.
Stress Mitigation for High-Value Crops
Used on fruit trees and cash crops to reduce disease damage and maintain commodity quality during disease prevalent seasons.
Green Planting Regimes
Matches production requirements for organic and green agricultural systems with favorable toxicological and residue characteristics.
Application Advantages and Market Positioning
Distinct Immune-Inducing Biocide Mechanism
Different from fungicides that directly kill pathogens, Lentinan SL stimulates crop self-defense, bringing unique differentiated selling points for finished agrochemical products.
Synergistic Value in Integrated Pest Management
Works synergistically with traditional fungicides, helping formulators create resistance-management oriented disease control packages.
User-Friendly Liquid Formulation
Soluble liquid form features easy measurement and rapid dissolution, improving operation convenience for large-scale farms.
Market Fit for Low-Residue Agricultural Demand
Natural biological origin caters to rising consumer demand for safer agricultural products, suitable for high-value export crop planting.
FAQ (Technical Q&A)
Q1: How does it differ from conventional chemical fungicides in mode of action?
A: It is a plant immune inducer, not a direct biocide. It activates the plant's own systemic acquired resistance (SAR) pathways, stimulating defense enzymes and pathogenesis-related proteins. Conventional fungicides kill pathogens directly, while it strengthens the plant's self-defense capacity.
Q2: Is it effective when applied after disease symptoms appear?
A: Best results are achieved with preventive application before disease onset. As an immune inducer, it requires time for the plant to build up resistance. For established infections, tank-mixing with a contact fungicide is recommended.
Q3: What is the difference between this and amino-oligosaccharin?
A: Both are plant immune inducers, but they originate from different sources and activate different defense pathways. Lentinan is a β-1,3-glucan from shiitake mushrooms, while amino-oligosaccharin is derived from chitosan. They can be used in rotation to broaden immune activation.
Q4: Does it develop resistance like chemical fungicides?
A: No. Because it activates the plant's own immune system rather than targeting a specific pathogen protein, resistance development is unlikely. This makes it suitable for long-term integrated disease management programs.
Q5: Can it be tank-mixed with alkaline pesticides?
A: No. Avoid mixing with strong alkaline pesticides or fertilizers, as this may reduce efficacy. It is compatible with most neutral and acidic agrochemicals.
Q6: What crops have shown the best response?
A: Vegetables (especially cucurbits and solanaceous crops), tobacco, rice, and fruit trees have shown strong responses. Field trials on zucchini virus disease demonstrated up to 74% preventive efficacy-11.
Q7: How does temperature affect efficacy?
A: Optimal activity occurs between 15–30°C. Below 10°C, plant immune response slows. Above 35°C, application should be timed to early morning or late afternoon.
Q8: Is it approved for organic agriculture?
A: Lentinan is a naturally derived polysaccharide from shiitake mushrooms. It is recognized as a low-risk plant protection material in many jurisdictions. Check local organic certification requirements for specific approval status.
Q9: How does Lentinan SL affect beneficial insects and pollinators?
A: It has no direct insecticidal activity and is not toxic to bees or beneficial insects at recommended application rates. It can be integrated into IPM programs without disrupting biological control agents.
Q10: Can it be applied through drip irrigation?
A: It is designed for foliar application. Soil application is not recommended because the immune-inducing effect requires contact with plant foliage to activate systemic resistance.
