Fytosave

The versatile Biocontrol solution with COS-OGA
for sustainable agriculture

Fytosave represents an alternative approach to biocontrol, utilizing an elicitor-based strategy to reinforce plant immune responses mainly against powdery mildew and some downy mildew. Unlike conventional fungicides relying on direct pathogen suppression, Fytosave ( with COS-OGA) enhances the plant’s natural defense mechanisms, making it a sustainable and effective tool in integrated pest management (IPM).

At the heart of Fytosave’s efficacy is its active substance, COS-OGA, a patented complex of oligosaccharides derived from chitosan (COS) and pectin (OGA). This unique molecular structure interacts with plant receptors to trigger systemic acquired resistance (SAR) pathway. These responses activate key physiological processes, such as the production of antimicrobial compounds, reinforcement of cell walls, and the modulation of defense-related gene expression. As a result, plants become more resilient to pathogen attacks ; lowering the need for synthetic chemical inputs.

By leveraging COS-OGA technology, Fytosave offers an environmentally friendly alternative that not only mitigates disease pressure but also helps reducing chemical residues in agricultural products. Its effectiveness has been validated over a dozen of years, in multiple field trials, proving its ability to improve overall crop health while maintaining compatibility with existing crop protection programs.

How Fytosave’s COS-OGA Biocontrol protects crops ?

This biocontrol helps plants defend themselves naturally against diseases like powdery mildew. Instead of killing the fungus directly like chemical sprays, it strengthens the plant’s immune system, making it more resistant to attacks. It works by encouraging the plant to produce natural protective substances, similar to how vaccines help our bodies fight off infections. This method is safer for the environment and prevents fungi from developing resistance, which can happen with traditional chemical treatments.

Fytosave proven performance in viticulture and beyond

Field trials have demonstrated Fytosave’s high efficacy, particularly in viticulture and horticulture:

Can be applied in combination with anti-powdery mildew and anti-downy mildew treatments at standard doses (2 to 4 sequential applications).

Up to 85% disease suppression in vineyards against powdery mildew.

Ideal for integration with sulfur-based and conventional mildew control programs, allowing reduced chemical inputs while maintaining crop protection.


Fytosave application protocol :

  • Target Crops: Vineyards, vegetables, small fruits and other authorized crops.
  • Dosage: 2-4 L/ha per application, depending on the crop.
  • Optimal Timing: Applied preventively at key phenological stages (pre-flowering, flowering, post-flowering) for maximum efficiency.
  • Maximum Applications Per Year: up to 8, depending on the crop.
  • Pre-Harvest Interval (PHI): 0-3 days, ensuring compliance with strict market requirements.
  • Re-Entry Interval (REI): 6 hours.
