Buctril Universal 560 EC

Synergy of Active Ingredients: How "Buctril Universal 560 EC" Works

The success of controlling stubborn broadleaf weeds in grain and corn crops lies in the precise combination of two components: 2,4-D (in ester form) and bromoxynil. This combination transforms the product into a tool with a dual mechanism of action, which is essential for controlling resistant species.

Technical Breakdown

• 2,4-D (systemic component): Acts as an auxin-like herbicide, causing metabolic disruption and abnormal tissue growth in weeds. The substance penetrates leaves quickly and translocates to growth points.
• Bromoxynil (contact component): Inhibits photosynthesis at the photosystem II level. This component "burns" the vegetative mass, providing a visual effect within hours of application.

The combination of systemic and contact action compensates for the individual limitations of each component. Bromoxynil ensures rapid results even in cooler weather, when the systemic action of 2,4-D might be slower. Conversely, 2,4-D ensures the complete destruction of the root systems of auxin-sensitive weeds.

Application and Agronomic Features

The product is formulated as an emulsifiable concentrate, ensuring excellent leaf coverage and wetting. Due to its selectivity, the herbicide effectively targets a wide spectrum of weeds, ranging from common lambsquarters and redroot pigweed to cleavers and smartweed. The recommended dosage is 0.7–1.0 L/ha. It is important to adhere to the regulation: only one application per season is allowed, with a pre-harvest interval of 45 days.

As a post-emergence herbicide, "Buctril Universal 560 EC" is most effective during early growth stages. This is critical for reducing competitive pressure on winter wheat, winter barley, and corn, helping to secure crop yields from the start.
