Traver, EC, (Acetochlor, 900 g/L)

Mechanism of Action and Selectivity

Trever, EC is based on acetochlor at a concentration of 900 g/L. It is a systemic soil-applied herbicide belonging to the chloroacetamides class. Its primary function is the inhibition of protein synthesis and the disruption of cell division in the meristematic tissues of germinating weeds. Due to its systemic action, the preparation penetrates the weed via the coleoptile (in grasses) or hypocotyl (in broad-leaved weeds), arresting their growth before they emerge above the soil surface.

Technological Composition Features

The emulsion concentrate formulation ensures optimal distribution of the active ingredient within the topsoil layer, creating a consistent 'herbicide screen'. The choice of acetochlor at this concentration allows for effective control of annual grasses and a wide range of broad-leaved weeds, which is critical during the initial growth stages of corn, sunflower, and soybeans. The selectivity of the product relies on the capability of crop plants to metabolize acetochlor, neutralizing its effect within their tissues, making Trever safe when application protocols are followed.

Application and Regulations

The product is applied as a pre-emergence herbicide, necessitating thorough soil preparation prior to sowing. The absence of soil clods and sufficient soil moisture are the determining factors for the effectiveness of the 'herbicide screen'. The application rate is 1.5–3 L/ha, with a limit of one application per season. The high concentration of the active ingredient requires strict adherence to dosage guidelines based on soil type: minimal rates are used for light, low-humus soils, while maximum rates are reserved for heavy, high-humus soils.

• Hazard Class 2: application requires standard personal protective equipment.
• Action type: soil barrier preventing the 'second wave' of weeds.
• Manufacturer: F.Shandong Qiaochang Chemical Co. Ltd. (China), ensuring compliance with the stated 900 g/L concentration.
