🌾 Quelex Complex Pak 4HA – Quelex 0.1 kg (Florasulam, Halauxyfen-Methyl) + Naceto 1 L (Diflufenican, Flufenacet)

Quelex Complex Pak combines Quelex (WG, leaf-acting, systemic) and Naceto (SC, soil/leaf) for comprehensive control of monocotyledonous and dicotyledonous weeds in winter and summer grains.

🌱 Benefits & Use

✅ Wide spectrum of action: cleavers, cornflower, poppy, chickweed, chamomile, shepherd’s purse, and others; grassy weeds including loose silky-bent (Apera spica-venti) thanks to flufenacet/diflufenican
✅ One pass is enough – clean crop stand in autumn or spring
✅ Fast effects: first symptoms within hours, dying off in days/weeks
✅ Gentle on following crops
✅ Convenience: Quelex = WG; Naceto = SC (both as concentrates)
