KVELKES 200, WG

Synergistic Formulation: Advanced Weed Control

QUVELEX 200, WG represents a high-tech approach to selective weed management, utilizing a three-component system: florasulam, halauxifen-methyl, and the safener cloquintocet-mexyl. The core innovation is Arylex™ active (halauxifen-methyl), a novel arylpicolinate chemistry. Unlike older auxin herbicides, it maintains high biological activity at temperatures as low as +2°C, providing a distinct advantage for early spring application in winter and spring cereals.

Technical Composition and Functionality

• Halauxifen-methyl: Functions as a synthetic auxin, causing rapid, irreversible physiological disruption in target weed tissues. Its low use rate makes it an environmentally efficient tool.
• Florasulam: Targets the acetolactate synthase (ALS) enzyme, inhibiting essential amino acid synthesis, which prevents cross-resistance development in common weed species.
• Cloquintocet-mexyl: Acting as a safener, it accelerates the metabolism of the active ingredients within the crop plant, ensuring the safety of wheat and barley even under harsh environmental conditions.

Practical Application Metrics

Formulated as water-dispersible granules, the product offers superior handling and mixing stability. With a recommended application rate of 0.05–0.075 kg/ha, it provides a cost-effective solution for controlling stubborn broadleaf weeds, including common ragweed (Ambrosia artemisiifolia), cleavers (Galium aparine), and common chickweed (Stellaria media). As a post-emergence herbicide, QUVELEX 200, WG targets weeds selectively, allowing for safe application during critical growth stages of cereals without inducing phytotoxicity. A single application per season effectively secures the crop’s nutrient uptake by eliminating weed competition.
