Metrix WG

Technical Potential of Metrix WG

The formulation is based on metribuzin (a triazine chemical class), which exhibits a distinct systemic effect. Its technical value lies in its ability to inhibit photosynthesis by blocking electron transport in photosystem II. This makes Metrix WG an essential tool in intensive farming for controlling annual broadleaf and some grass weeds.

Molecular Mode of Action

The product is absorbed by both the root system and leaves of weeds, moving via the xylem to the meristematic tissues. The choice of "water-dispersible granules" as the formulation is driven by technological efficiency: they provide high stability of the spray solution, minimize dust during tank mixing, and ensure precise dosing. Once in the soil, the active ingredient forms a "protective barrier" that prevents the emergence of subsequent weed flushes.

Practical Application Details

• Selectivity: The herbicide selectively targets the metabolism of specific species without suppressing the crop (soybeans, potatoes, tomatoes) when used according to the guidelines.
• Soil Control: The high sorption capacity of metribuzin allows it to remain in the top layer of the soil, providing prolonged protection until row closure.
• Application Timing: This is a pre-emergence herbicide. Its use as a soil barrier requires sufficient soil moisture for the activation of active ingredients.

The application rate ranges from 0.5 to 1.0 kg/ha (depending on the soil texture and weed species composition). It is critical to note its Class 2 hazard rating: using personal protective equipment is mandatory when handling the concentrate. A strict limitation is set to a maximum of one application per season to prevent resistance development and to comply with environmental safety standards.
