Prometrax, KS (permethrin, 500 g/l)

Technological Precision in Soil-Applied Protection

Prometrex, SC from the Israeli manufacturer Adama Agan Ltd. is a specialized tool designed to create a reliable 'protective screen' on the soil surface. The product is based on prometryn at a concentration of 500 g/L, formulated as a suspension concentrate. This specific formulation ensures optimal stability of the active ingredient in tank mixtures and provides uniform coverage during application.

Mechanism of Action: Photosynthesis Inhibition

As a systemic, selective herbicide, Prometrex is absorbed by weeds primarily through the root system and developing sprouts. The active ingredient inhibits photosynthesis in the cells of susceptible plants, leading to their elimination before they emerge from the soil or at the 'white thread' stage. This makes it a preferred solution for safeguarding crops during critical early growth phases.

Target Spectrum and Selectivity

The product demonstrates high efficacy against a broad range of broadleaf weeds, including:

• Common ragweed (Ambrosia artemisiifolia);
• Common lambsquarters and redroot pigweed;
• Field mustard and shepherd's purse;
• Common chickweed, scentless chamomile, and common purslane.

The selectivity of Prometrex allows for safe use on coriander, carrots, soybeans, sunflowers, common beans, and potatoes. When applied at the recommended rate of 2–4 L/ha, it establishes a persistent barrier without causing phytotoxic stress to the target crop.

Practical Implementation Tips

The effectiveness of Prometrex is highly dependent on proper soil preparation. The field surface should be fine-textured without large clods to ensure a continuous and unbroken herbicide screen. Soil moisture is a critical parameter for success, as water is required to activate the active ingredient. Classified under hazard class 3, the product requires standard safety precautions. For best results, it should be applied as a single pre-emergence treatment.
