Triactiv c.e.

Three-component formula for beet crop weed control

"Triaktiv K.E.", manufactured by Zhejiang Agrin Company Ltd., is a selective systemic herbicide engineered for the management of difficult-to-control dicot weeds in sugar, table, and fodder beet crops. The formulation relies on the synergism of three active ingredients: desmedipham, phenmedipham, and ethofumesate.

Technical Breakdown of the Formulation

• Desmedipham & Phenmedipham System: These carbamate-based substances act by blocking photosynthesis within weed tissues. They penetrate the leaf surface rapidly, disrupting electron transport, which halts growth and eventually leads to the necrosis of sensitive species like common lambsquarters and redroot pigweed.
• The Role of Ethofumesate: As a benzofuran derivative, this active ingredient provides crucial residual soil activity. It inhibits cell division in meristematic tissues, which is vital for suppressing weeds that are still in the germination phase. This makes the preparation a versatile tool against multiple flushes of weeds.

Operational Performance

The product is formulated as an emulsifiable concentrate, ensuring high solubility and stability in the spray tank. Its selective nature allows for safe post-emergence application on the crop. To achieve optimal results, farmers should adhere to the application rate of 1–3 liters per hectare, depending on the weed growth stage and density.

Key Application Parameters:

• Target Spectrum: Common lambsquarters, redroot pigweed, shepherd's purse, purple dead-nettle.
• Maximum Seasonal Applications: 3.
• Pre-Harvest Interval (PHI): 56 days.
• Hazard Class: 3.

By leveraging the systemic mechanism and combining distinct chemical classes, "Triaktiv K.E." provides a reliable solution to minimize weed competition during the critical early growth stages of beets, without causing damage to the crop itself.
