Centor, KE (clethodim, 240 g/l)

Effective Control of Grass Weeds in Broadleaf Crops

"Centor, EC" (clethodim 240 g/L) is a high-performance solution for farms battling aggressive annual and perennial grass weeds. With a high concentration of the active ingredient, it effectively targets persistent weeds like couch grass (Elymus repens), barnyard grass, yellow foxtail, wild oats, and common windgrass. Developed by Jiangsu Fengshan Group and Nanjing Fengshan Chemical (China), this formulation ensures reliable and consistent performance for commercial farming operations.

Practical Application Scenarios

As a systemic post-emergence herbicide, "Centor" is a preferred choice for integrated weed management programs. Agronomists typically utilize it for:

• Technical Crop Protection: Essential for protecting soybean, sunflower, rapeseed, and flax fields where preventing grass competition is critical during the early stages of development.
• Vegetables and Potatoes: The product’s selectivity allows for safe use on potato and forage beet crops without compromising their growth potential.
• Control of Persistent Weeds: Unlike standard graminicides, the 240 g/L clethodim formulation is capable of tackling even overgrown grass weeds, provided the application rates (0.2–0.8 L/ha) are strictly followed.

The product acts via the leaf surface, ensuring rapid systemic absorption. It inhibits fatty acid biosynthesis, leading to the total destruction of both the aerial biomass and the root system (essential for rhizomatous weeds like couch grass). Designed for a single application, it offers a cost-effective solution for comprehensive field protection.

Technical Considerations for Agronomists

The emulsifiable concentrate (EC) formulation ensures excellent tank-mix solubility and even coverage across leaf surfaces. Despite its Hazard Class 3 rating, strict adherence to application guidelines guarantees high selectivity. To achieve optimal results, it is crucial to apply the herbicide during the active growth phase of the weeds, when they are most susceptible to the systemic action of clethodim.
