Securing Winter Rapeseed: Pre-emergence Weed Control

For agronomists, protecting winter rapeseed during its early growth stage is the foundation of a successful yield. Kolozon, EC from Rangoli, acts as a soil-applied herbicide designed to eliminate competitive weeds before they can even establish themselves in the field.

Targeting the Main Threats

The active ingredient, clomazone, is known for its high efficiency against problematic broadleaf weeds that typically threaten young rapeseed stands. By creating a protective barrier in the soil, Kolozon targets:

• Common lambsquarters and shepherd's purse;
• Common chickweed;
• Cleavers, a notorious competitor for nutrients;
• Purple dead-nettle and field pansy.

Practical Application Insights

Kolozon is a selective, systemic, pre-emergence herbicide. It is designed to be applied to the soil immediately after sowing, before the crop emerges. By doing so, the product establishes a 'shield' that is absorbed by emerging weed sprouts, halting their growth at the root level.

The application rate ranges from 0.5 to 1.0 liters per hectare, depending on soil type and the expected weed density. Being a selective herbicide, it effectively manages the weeds while remaining safe for the rapeseed crop when the instructions are followed. Note that it is intended for a single application per season, making it a powerful tool for a 'clean start' strategy.

Why Choose Kolozon?

Agricultural operations rely on Kolozon for its targeted approach. By preventing weed competition during the early growth period, you ensure that the rapeseed has optimal access to moisture and nutrients, which is vital for winter hardiness. Classified as a Class 3 hazard, it fits well into standard modern agricultural workflows, requiring only basic safety precautions.
