PROMAN 500 SC

Metobromuron: Soil-Applied Defense Mechanism

At the core of "PROMAN 500 SC" is the active ingredient metobromuron (500 g/l). Belonging to the urea derivative class, it acts as a potent inhibitor of photosynthesis. Upon application to the soil, the product molecules are absorbed by weed seeds and sprouts, effectively blocking electron transport in photosystem II. For farmers, this means the suppression of weeds at the "white thread" stage, preventing competition before the crop even emerges.

Why the SC Formulation Matters

The manufacturer, Certis Belchim B.V., developed this product as a Suspension Concentrate (SC). This technical decision is vital for a soil-applied herbicide: the micro-particles are evenly dispersed within the spray tank, preventing sedimentation and ensuring the formation of a stable, uniform "film" on the soil surface. This structure bonds effectively with soil colloids, minimizing the risk of leaching into deeper soil layers, even during moderate rainfall.

Selective Performance and Practical Application

As a selective systemic herbicide, "PROMAN 500 SC" demonstrates high crop tolerance when used on soybeans, sunflowers, and potatoes. When applied correctly at a rate of 2–3 L/ha, the product effectively manages annual broad-leaved and specific grass weeds. A crucial technical detail: a single pre-emergence application establishes a defensive barrier essential for the first 3–5 weeks of the growth cycle—the phase where crops are most vulnerable to competition for moisture and soil nutrients.

• Action Type: Soil-applied, pre-emergence herbicide.
• Hazard Class: 3.
• Target Pests: A broad spectrum of annual broad-leaved and select annual grasses.
