Lazurit

Why Lazurit remains a benchmark in potato and soybean protection

When it comes to controlling a wide range of broadleaf and grass weeds, Lazurit from ZAT Firma Avgust (Vurnary) holds its ground as a time-tested solution. Its primary advantage is versatility. It is a systemic herbicide based on metribuzin that can be applied both pre-emergence (soil application) and post-emergence, working directly on leaf surfaces.

Key Benefits

• Selectivity: The product is ideal for use on potato, tomato, soybean, and corn crops, providing weed control without suppressing the crop when used at the recommended rates (0.5–1.0 l/ha).
• Dual Action: Metribuzin is absorbed by both roots and leaves, ensuring reliable control of aggressive weeds such as white goosefoot, black nightshade, field mustard, and shepherd's purse.
• Wide Application Window: Depending on the weed and crop growth stages, you can adjust the application strategy, which is critical in volatile weather conditions.

Usage Details

The strength of Lazurit lies in its systemic nature, but it is important to observe Class 3 safety protocols. It must be handled with appropriate protective measures. A significant advantage for farmers is the short pre-harvest interval—only 1 day—allowing for rapid response to new weed flushes. It is a workhorse for farms that prioritize clean fields with predictable costs.

Limitations and Considerations

Despite its high efficacy, Lazurit requires strict dosage adherence. On light, low-humus soils, dosages should be reduced to prevent crop phytotoxicity. Additionally, it is not a standalone cure-all for deep-rooted perennial weeds, which may require tank mixtures for complete control.
