Central

Systemic Control of Grass Weeds: Technical Insight

"Central" is formulated as an emulsifiable concentrate containing clethodim, a highly selective post-emergence herbicide. It functions as an ACCase inhibitor, blocking fatty acid synthesis—a vital metabolic process in grass weeds such as quackgrass (Agropyron repens) and green foxtail. Unlike contact herbicides, its systemic nature allows for rapid leaf penetration and translocation to active growth points, including the rhizomes of perennial grasses.

Mechanism of Action and Crop Safety

The selectivity of clethodim ensures that broad-leaved crops, including soybeans, canola, sunflowers, flax, carrots, onions, and fodder beets, remain unaffected. By targeting a biological process specific to grass species, the herbicide effectively shuts down weed development shortly after application, with complete necrosis typically occurring within 7 to 10 days. The dosage of up to 0.5 L/ha provides a cost-effective solution for field-wide weed management.

Operational Advantages

• Systemic Efficacy: Capable of controlling weeds that have progressed beyond early growth stages, thanks to its ability to reach established root systems.
• Strategic Application: Designed for post-emergence leaf treatment, offering flexibility in responding to specific weed pressure during the growing season.
• Safety Profile: With a re-entry and pre-harvest interval of just 1 day, it integrates seamlessly into high-intensity agricultural cycles.

Manufactured by Shanghai Shengnong Pesticide Co. Ltd. (Shanghai, China), "Central" represents a precise technological solution for modern agronomy, focusing on targeted weed control without the risk of phytotoxicity to the primary crop.
