Ridomil Gold Fungicide
Ridomil Gold fungicide (Metalaxyl-M 4% + Mancozeb 64% WP) is a globally trusted dual-action fungicide developed by Syngenta for effective management of devastating diseases like Late Blight and Downy Mildew.
It combines the powerful systemic action of Metalaxyl-M with the broad-spectrum contact protection of Mancozeb, offering both preventive and early curative control. Ridomil Gold is widely recommended for high-value crops such as potato, tomato, grapes, and vegetables where disease pressure can significantly reduce yield and quality.

Ridomil Gold Features and Benefits
Dual-Action Protection:
Metalaxyl-M moves systemically inside the plant, protecting new growth from within, while Mancozeb forms a protective barrier on the plant surface.
Systemic “Inside-Out” Defense:
Metalaxyl-M is absorbed by roots and leaves and transported upward (acropetal movement), controlling fungal infections at early stages.
Broad-Spectrum Multi-Site Protection:
Mancozeb acts on multiple enzyme sites of fungi, reducing the risk of resistance development.
Preventive and Early Curative:
Best applied before infection or at the very first appearance of symptoms for maximum effectiveness.
Rain Fastness:
Becomes rainfast within approximately 2–3 hours after spraying.
Resistance Management Tool:
Combination of site-specific and multi-site fungicide chemistry makes it suitable for integrated disease management programs.
Mode of Action Explained
-
Metalaxyl-M: Inhibits RNA polymerase in fungi (Oomycetes group), stopping fungal growth and spread inside plant tissues.
-
Mancozeb: Disrupts fungal enzyme activity by reacting with sulfhydryl groups, preventing spore germination and fungal development.
This complementary action ensures both internal and external protection.
