Cedroz formulation technology

Research has proven the importance of terpenes in crop protection. However, commercial use has previously been limited due to their high volatility, phytotoxicity, and poor solubility, which make these compounds difficult to extract and formulate. Sustaine® microencapsulation, patented by Eastman collaborator Eden Research PLC, provides a unique, environmentally friendly solution that enables terpenes to be used effectively in crop protection.

"We are seeing increasing consumer demand and a policy push for products that support sustainable agriculture with greatly reduced or no pesticide residues and with no or very low preharvest intervals, all while maintaining efficient crop management and production. Without products such as Cedroz, consumers could very well be facing a future deficit in the availability of quality, pesticide-free food.”

High-tech microencapsulation and gradual release

This natural technology is based on yeast cells that are a by-product of numerous commercial production processes. The capsules are microspheres characterized by a protein, lipid, and polysaccharide fraction that constitutes a porous structure. In the formulation phase, they incorporate two active terpenes—thymol and geraniol—inside the capsules.

The innovative system promotes suspensibility without using emulsion solvents. Once applied to the soil, the capsules provide modulated and gradual release of the terpenes through their microporous walls.

When Cedroz is applied via the irrigation system, a mixture of both free and encapsulated terpenes will enter the soil. The already-free terpenes have a knockdown activity against the nematodes present in the soil.

After irrigation, the amount of water is very low and, due to a particular equilibrium, no more terpenes are released, keeping the remaining terpenes in the capsules.

Further irrigation will allow the remaining terpenes to release into the soil.

The lethal effect of Cedroz on nematodes

An in vitro test demonstrated the lethal effect of Cedroz on root-knot nematodes (Meloidogyne). Watch the following video to find out more.
