Prometrax CS

Technological nuances of Prometrex CS formulation

The active ingredient of Prometrex CS is prometryn (500 g/l), formulated by Adama Agan Ltd., Israel, as a suspension concentrate. Unlike powder-based formulations, this liquid technology ensures the creation of a stable colloidal system that prevents sedimentation in the sprayer tank and nozzle clogging. This is a critical technical advantage for a soil-applied herbicide, where uniform field coverage is the primary determinant of efficacy.

Mechanism of selective action

Prometrex CS acts as a systemic soil-applied herbicide, absorbed by the roots and shoots of germinating weeds. The prometryn molecules inhibit the photosynthetic process (Hill reaction), resulting in the death of susceptible annual broadleaf and grass weeds before they emerge. Its high selectivity allows for safe use in crops such as carrots, coriander, soybeans, sunflower, beans, peas, and potatoes, provided the labeled application rate of 2–4 L/ha is strictly followed.

Operational guidelines for field application

• Soil barrier stability: The product’s effectiveness is highly dependent on soil moisture. Moisture activates the active ingredient, creating a persistent chemical barrier that keeps fields clean for 6–8 weeks.
• Application window: Designed for pre-emergence use, the herbicide works best when applied immediately after sowing, before the crop emerges.
• Quality assurance: The advanced suspension technology from Israeli R&D minimizes phytotoxicity risks. To maintain crop safety, the regulatory limit of one application per season must be strictly observed. As a Class 3 hazard product, it requires standard safety protocols during tank mixing and application.

Integrating Prometrex CS into the crop protection cycle eliminates weed competition at the most vulnerable early growth stages. Its physical stability ensures precise field-scale control, providing a reliable foundation for yield protection without the need for intensive mechanical weeding.
