Metalaxyl-M 35% FS delivers systemic oomycete protection from the moment the seed is planted. By coating the seed with a precise, uniform film of the R-enantiomer active, it creates a protective zone around the germinating seedling — defending against Pythium, Phytophthora and downy mildew during the critical emergence window when seedlings are most vulnerable.
Mode of Action
Metalaxyl-M inhibits RNA polymerase I in oomycete pathogens, blocking ribosomal RNA synthesis and halting protein production. This Group 4 mechanism is highly specific to oomycetes, providing targeted protection against Pythium, Phytophthora and downy mildew without disrupting beneficial soil microorganisms.
FS Formulation Advantages
- Optimized Viscosity: Engineered for uniform seed coating with commercial treatment equipment — no runs, drips, or uneven patches
- Uniform Coating: Precise film formation ensures every seed receives the target dose for consistent stand establishment
- Bright Color for Visibility: Integrated colorant provides instant visual confirmation that seeds have been treated, preventing mixing errors and ensuring quality control
- Flowable Convenience: Ready-to-use liquid eliminates dust and handling hazards associated with powder seed treatments
Seed Treatment Application
- Application Rate: 100–300 mL per 100 kg seed, adjusted by crop and disease pressure
- Equipment Compatibility: Designed for standard commercial seed-treatment machines (batch and continuous)
- Tank-Mix Partners: Compatible with fludioxonil, thiram, mancozeb and insecticide seed treatments for comprehensive seedling protection packages
- Drying Time: Rapid drying on seed surface for immediate bagging and handling
Who It Is For
- Seed treatment companies building oomycete-protection product lines
- Seed coating brands targeting corn, soybean and vegetable stand establishment
- OEM clients needing FS-grade formulations with colorant and viscosity customization
- Distributors supplying integrated seed-treatment packages for emerging markets

Frequently Asked Questions
What is the difference between Metalaxyl and Metalaxyl-M?+
Metalaxyl-M is the biologically active R-enantiomer of metalaxyl. It provides the same fungicidal activity at approximately half the application rate of racemic metalaxyl, reducing the environmental load while maintaining full efficacy against oomycete pathogens.
Why is FS the preferred formulation for seed treatment?+
FS (flowable concentrate for seed treatment) is specifically engineered for seed coating: optimized viscosity ensures uniform film distribution on seed surfaces, bright colorants provide visual confirmation of treatment coverage, and the flowable form integrates seamlessly with commercial seed-treatment equipment.
Which crops and diseases does Metalaxyl-M 35% FS target?+
Primarily oomycete seedling diseases across a wide crop range: Pythium and Phytophthora damping-off in corn, soybean, sunflower and vegetables; downy mildew in millet and sunflower; and Phytophthora root rot in legumes. It is often tank-mixed with contact fungicides for broader seedling protection.
Can Metalaxyl-M 35% FS be combined with other seed treatments?+
Yes — it is commonly combined with fludioxonil, thiram, or mancozeb for multi-disease seed treatment packages. Agrospear can supply pre-formulated combinations or separate components for on-site blending per client specifications.
What is the minimum order to customize a formulation?+
MOQ is 20+ tons per approved formulation, subject to raw material and packaging requirements tons for standard volume production, with pilot runs from 5 tons (custom formulation or new packaging) and 20+ tons (new formulation requires dedicated registration; registration adds 60–90 days) for custom packaging tooling.
How long do samples and production take?+
Samples are ready in 7–14 days; batch production completes in 25–35 days after confirmed PO and deposit.
Can I change colors, artwork and the logo?+
Yes — label design, color coding, logo placement, packaging and accessories are all customizable on every formulation platform. Share your logo and we produce a visual proof before production.
How is quality controlled before shipment?+
Every batch passes a 100-point production checklist and a HPLC purity · GC residue · stability test specification test before packing; batches exceeding specification limits are auto-rejected.
