PARUS 500, KS, herbicide

Why Parus 500 SC is the choice for a weed-free start

During the sowing of sunflowers and corn, farmers face a tough choice: rely on a single component or use a comprehensive solution. Parus 500, SC from the Ukrainian manufacturer «Promin-Agrokhim» is a soil-applied herbicide that handles the hard work of clearing fields before the crops even emerge.

The Power of a Double Strike

The key differentiator of this product is its combination of two active ingredients: terbuthylazine and metolachlor. This blend makes it a powerful systemic tool with selective action:

• Metolachlor inhibits the germination of annual grasses and certain broadleaf weeds, creating a reliable «barrier» in the topsoil.
• Terbuthylazine boosts this defense, effectively targeting a wide range of broadleaf weeds that often escape single-active-ingredient treatments.

Unlike cheaper mono-preparations, «Parus 500» works holistically, significantly reducing the risk of secondary weed infestation. This is critical for high-pressure fields where missing even one wave of weeds can result in a 20–30% yield loss.

Application and Performance

As a pre-emergence herbicide, Parus 500 requires proper soil preparation. A level field surface and sufficient moisture in the topsoil are prerequisites for optimal performance. Application rates range from 1.0 to 3.0+ L/ha depending on soil type (on heavy clay soils with high humus content, dosages should be increased to ensure a consistent protective layer).

Why it stands out:

• Selectivity: The crop remains safe while the herbicide clears the surrounding space.
• Extended Residual Control: A single application ensures field cleanliness during the early, critical growth phases.
• Convenient Formulation: The suspension concentrate dissolves easily, prevents nozzle clogging, and ensures uniform field coverage.

Although it is classified as a Hazard Class 3 chemical, strict adherence to application protocols ensures effective control of annual grasses and broadleaf weeds without phytotoxicity risks for corn or sunflowers. It is an ideal choice for operations focused on intensive farming looking to eliminate weed competition before the active vegetation stage begins.
