Cedroz mode of action

Cedroz™ post-planting bionematicide is a suspension of capsules in an aqueous solution (CS) that contains a mixture of two active compounds: thymol and geraniol. These compounds, known as monoterpenes, are effective against nematodes through different mechanisms.

What are root-knot nematodes?

Root-knot nematodes are small, plant-parasitic nematodes (genus Meloidogyne) that cause root knot. Mostly found in areas with warm climates or short winters, root-knot nematodes are found in all agricultural regions worldwide and can affect hundreds of different plant species.

Their larvae infect plant roots, causing the development of root-knot galls that drain the plant’s photosynthate and nutrients. Severe infection in mature plants results in reduced yields, while infection in juvenile plants can be lethal.

How does Cedroz work against
root-knot nematodes?

Thymol and geraniol act against nematodes through different mechanisms. Due to their lipophilic nature, they accumulate in the cell membranes of the root-knot nematodes, disrupting their structure and causing a leakage of fundamental cellular substances (lysis).

When the cell membrane is disrupted, the monoterpenes (thymol and geraniol) interfere with the mitochondria, causing them to malfunction. As a result, the mitochondria can’t generate energy for the organism due to a depletion of adenosine triphosphate (ATP), the main carrier of cellular energy. This ultimately leads to the death of the cell.

How does Cedroz affect nematode cell membranes?

Mitochondria are membrane-bound organelles found in the cells of most eukaryotic organisms. Named after the Greek words for thread and granule, mitochondria are sometimes referred to as the powerhouse of the cell because they produce most of its energy.

Mitochondria facilitate the production of ATP, which is the main source of chemical energy in living organisms. Damage to the cell membrane leads to the depletion of ATP, preventing many cellular processes from occurring.
