Centur

Mechanism of Action and Selectivity of "Centur"

"Centur" is a selective graminicide based on clethodim, developed by DVA Chemicals Co. Ltd. (China). The core technical advantage of this product lies in its systemic action on grass weeds, penetrating the leaf surface and rapidly translocating to meristematic tissues and the root system. The active ingredient inhibits lipid synthesis, leading to the immediate cessation of growth in targeted weeds within hours of application.

Technical Specifications

• Formulation: Emulsifiable concentrate, ensuring high stability of the tank mix and optimized adhesion to the waxy cuticle of grass leaves.
• Action Type: A systemic, post-emergence selective herbicide. This formulation allows for use on sugar beet, soybean, sunflower, flax, and potato crops without the risk of phytotoxicity to the main crop.
• Weed Control Spectrum: The product demonstrates high technical efficacy against couch grass (Elymus repens) and a wide range of annual and perennial grass weeds.

Application Best Practices

The effective use of "Centur" requires strict adherence to the application protocol. The application rate ranges from 0.2 to 0.8 L/ha, depending on the weed species composition and growth stage. Application is performed in a single pass over actively growing weeds. A critical technical constraint is the pre-harvest interval (PHI) of 60 days, which must be accounted for in crop protection planning. Due to its selective action, "Centur" is an essential tool in integrated weed management programs for broad-leaved crops where mechanical weeding is inefficient or unfeasible.
