Combating broomrape: Why Impresis is a key tool for sunflower growers

For those cultivating herbicide-tolerant sunflower hybrids, selecting the right crop protection product is critical. Impresis, produced by Agrokhimichni Investytsii, is a potent systemic herbicide formulated with a classic combination of imazamox and imazapyr. This dual-active ingredient blend offers a powerful solution for fields plagued by both annual weeds and persistent parasitic plants.

Key Advantages of Impresis

• Broomrape Management: The standout feature of Impresis is its efficacy in controlling Orobanche (sunflower broomrape), making it an essential tool for fields with high parasite pressure.
• Broad-Spectrum Control: It effectively eliminates difficult-to-control weeds, including common ragweed, redroot pigweed, lambsquarters, cleavers, and field sow thistle.
• Systemic Action: As a post-emergence herbicide, it is absorbed through the leaves and translocates throughout the plant’s vascular system, inhibiting amino acid synthesis and preventing regrowth.

Operational Considerations

Impresis is a selective herbicide designed for post-emergence application, ideally when the sunflower crop is in the 2–4 true leaf stage. The water-soluble concentrate is designed for efficiency, with a standard application rate of 1.0–2.0 L/ha. While it provides excellent control in a single pass, farmers should be aware of the soil residual effects of imazapyr. Crop rotation should be planned carefully, as sensitive crops may require a specific waiting period before planting in the following season.

For agricultural producers aiming for high-intensity sunflower production, Impresis offers a reliable balance between efficacy and ease of use. It is the optimal choice for those needing to suppress weed competition and parasitic infection with a single, highly effective application.
