Terbi-S, CS, herbicide

Why farmers choose Terbi-S for corn protection

In intensive farming, weed control at the early stages of corn development is a key determinant of final yield. «Rangoli» offers a solution with «Terbi-S, SC» — a selective systemic herbicide that manages field maintenance before the crop even emerges.

The power of triazines in soil control

The primary active ingredient in this herbicide is terbuthylazine, belonging to the triazine class. Unlike many contact alternatives, Terbi-S works through the soil. Its main feature is the creation of a «protective screen» that suppresses germinating seeds of broadleaf and certain annual grass weeds. Due to its systemic action, the product blocks photosynthesis in weeds, leaving them no chance to compete with corn for moisture and nutrients.

Advantages and limitations

• Selectivity: Corn exhibits high tolerance to terbuthylazine, allowing for application without the risk of phytotoxicity, even under unfavorable weather conditions after planting.
• Pre-emergence control: Using the product before emergence eliminates the challenge of managing «waves» of weeds during the critical early growth period.
• Efficiency: A dosage rate of 4–4.5 L/ha allows for the creation of a stable concentration of the active substance in the topsoil layer.

It is important to note that Terbi-S is a single-application tool (maximum one treatment). It requires careful soil preparation: optimal effect is achieved when applied to well-tilled, moist soil. If soil cloddiness is high, the effectiveness may decrease as the protective layer becomes uneven.

Who is this solution for?

This product from «Rangoli» is optimal for farms practicing conventional or minimum tillage that aim to minimize corn field weed infestation in the early stages. This is a «foundational» herbicide: it is not intended for combating already established adult weeds, but it excels at preventing competition, ensuring a «clean start» for the corn.
