Buctril 327,5 EC, KE

Mechanism of Action and Selectivity

Buktril 327.5 EC is a high-performance contact herbicide featuring bromoxynil (327.5 g/L). The active substance inhibits photosynthesis in weeds by blocking electron transport in photosystem II immediately upon contact with the leaf surface. This specific mode of action provides the necessary selectivity required for application in onion crops, ensuring that the target weeds are eliminated while the crop remains unharmed.

Advantages of the Emulsifiable Concentrate Formulation

The emulsifiable concentrate (EC) formulation is engineered to optimize the penetration of the active ingredient through the waxy cuticle of broad-leaved weeds. Given the unique morphological structure of onion leaves, the ability of Buktril 327.5 EC to remain stable on the leaf surface and facilitate rapid systemic-like contact uptake is its primary technical advantage in professional agronomy.

Application Guidelines

• Type of Application: Post-emergence, foliar herbicide applied directly to growing weeds.
• Dosage: Optimal control is achieved at a rate of 0.5–1 L/ha. Effectiveness is highest when applied to young weeds at the 2–4 leaf stage.
• Treatment Frequency: Strictly limited to one application per season to manage resistance and adhere to environmental safety regulations.

Classified under Hazard Class 2, the product requires standard precautionary measures during preparation and handling. Its selective nature makes it a cornerstone for crop protection in onion production, offering a precise way to manage broad-leaved weed pressure without compromising crop development.
