Protecting Sunflower Yields with «Hriznyi Ekspert»

In modern sunflower farming, particularly with hybrids resistant to tribenuron-methyl, selecting the right herbicide is a critical step for protecting potential yields. «Hriznyi Ekspert» (by Nertus) is a selective, systemic post-emergence herbicide designed to eliminate broad-leaved weeds without stressing the crop.

How It Works

The active ingredient, tribenuron-methyl, acts by inhibiting the acetolactate synthase (ALS) enzyme, which is essential for cell division in weeds. Because it is systemic, the product is absorbed through the leaves and travels through the plant, ensuring complete control. Visible effects—such as chlorosis and necrosis—are typically seen within 5 to 10 days, while growth stops almost immediately after application.

Target Weeds

This herbicide is highly effective against a wide range of common threats in sunflower fields, including:

• Problematic weeds like Ambrosia artemisiifolia (common ragweed) and Amaranthus retroflexus (redroot pigweed).
• Mustard varieties: field mustard and wild radish.
• Other common weeds: common lambsquarters, shepherd's purse, common chickweed, and purple dead-nettle.

Operational Benefits

«Hriznyi Ekspert» comes in the form of water-dispersible granules, which are favored by farmers for their ease of mixing and superior solubility in spray tanks. When applied during the 2–6 true leaf stage of the sunflower, the herbicide allows the crop to gain a significant head start over any weed pressure.

Why choose this product? For agricultural producers relying on tribenuron-resistant genetics, «Hriznyi Ekspert» provides a cost-effective, high-impact solution. By focusing on a single application per season, you can effectively manage field hygiene and ensure the crop has optimal access to water and nutrients. It is a proven, reliable choice for those looking for consistency in their crop protection strategy from a trusted Ukrainian manufacturer, Nertus.
