🏷️ Ridomil Gold MZ 68 WG – Systemic + Contact Fungicide for Oomycete Diseases
📝 Product Description
Ridomil Gold MZ 68 WG (Syngenta) is a premium dual-action fungicide combining Metalaxyl‑M (40 g/kg) and Mancozeb (640 g/kg). The systemic agent (Metalaxyl‑M) is absorbed rapidly and offers internal protection including new growth, while Mancozeb forms a protective film over plant surfaces to prevent spore germination. This powerful formulation delivers both curative and preventative control against diseases like late blight (Phytophthora infestans) and downy mildew (Plasmopara spp.) across crops such as potato, tomato, vine, onion, cucumber, and more.
