Nopasarán, KS (metazachlor, 375 g/l + imazamox, 25 g/l)

Clean fields with minimal effort

When working with Clearfield technology, weed pressure in winter rapeseed becomes a manageable task. Nopasaran, SC is the tool that allows you to clear the field in a single pass. What I value most about this product is its selectivity: it effectively eliminates lamb's quarters, amaranth, mustard, and cleavers, all while keeping the crop completely safe.

Application and Effectiveness

This product is a suspension concentrate with systemic action. Its core strength lies in the combination of metazachlor and imazamox. In practical terms, this means metazachlor provides soil-based control of new germination, while imazamox provides effective post-emergence control through the foliage. Crucially, as a post-emergence herbicide, it must be applied specifically after rapeseed emergence. A dosage of 1.2–1.5 L/ha ensures complete field control when timed correctly with weed growth stages.

Practical Advice for Growers

• Crop rotation: due to its systemic nature, carefully plan subsequent crops in the rotation.
• Timing: do not delay; treat weeds while they are young and most vulnerable.
• Pre-harvest interval: there is a 60-day safety period before harvest, so plan your harvesting schedule accordingly.
• Efficiency: one application per season is usually sufficient when applied correctly.

Product quality is backed by BASF production facilities in Europe and the USA. Given its Hazard Class 3 rating, standard safety precautions are required. However, the reliability and predictable results make this herbicide a foundational solution for those cultivating imidazolinone-resistant rapeseed hybrids.
