Quadris Ridomil Gold SL is a broad-spectrum fungicide suspension concentrate used primarily in potatoes to control various soil-borne and foliar diseases. It contains two active ingredients: azoxystrobin (77.1%) and mefenoxam (22.9%). It is designed for in-furrow applications, where the product is applied in a water spray into the furrow just before seeding. This product is effective against a range of pathogens including Rhizoctonia solani, Phytophthora infestans, and various blights and rots. When using this product, technicians should be aware of rotational restrictions; for example, there is a 0-day planting time from the last application for certain crops like Brassica and carrots, while others require longer intervals. Handling requires specific Personal Protective Equipment (PPE), including chemical-resistant gloves of barrier laminate, butyl rubber, nitrile rubber, or neoprene rubber (all > 14 mils), long-sleeved shirts, long pants, and shoes plus socks. Users must avoid application during temperature inversions and high wind speeds to prevent drift. The label emphasizes that the product is phytotoxic to certain apple varieties if drift occurs. Always follow the specific use rates based on row spacing as detailed in the application tables to ensure efficacy and compliance with the Worker Protection Standard (WPS).
