Advanced Weed Control with Zefir 300, SL

Zefir 300, SL, manufactured by the Hong Kong-based company 'Three Delta Company International', is a specialized systemic herbicide designed for effective crop protection. Built around Clopyralid, a powerful active ingredient known for its precision, this product has become a reliable asset for managing fields of winter wheat, winter barley, maize, and fodder beet.

Targeting Tough Weeds

The primary strength of Zefir 300 lies in its selective action. It targets difficult-to-control perennial weeds, effectively penetrating the vascular system to reach the root structures. This is particularly vital for farmers battling infestations of:

• Cirsium arvense (Canada thistle)
• Sonchus arvensis (Perennial sow thistle)
• Matricaria inodora (Scentless chamomile)
• Centaurea cyanus (Cornflower)
• Acroptilon repens (Russian knapweed)

Application Strategy

As a post-emergence foliar herbicide, Zefir 300 allows for flexible application timings during the growing season. The water-soluble concentrate (SL) formula is easy to prepare and ensures stability within tank mixes. With a recommended application rate of 0.1–0.3 L/ha and a limit of one application per season, it offers a highly efficient and cost-effective solution for large-scale agricultural use.

Classified as a Hazard Class 3 product, Zefir 300 prioritizes both effectiveness and careful management. By choosing this selective herbicide from 'Three Delta Company International', producers gain a tool that eliminates competitive pressure from weeds, allowing crops to maximize their yield potential without the risk of significant phytotoxicity when applied according to the label requirements.
