Quadris Ridomil Gold® Now Available for Use on Potatoes

Syngenta Crop Protection.


Greensboro, NC (May 17, 2006) – Quadris Ridomil Gold® fungicide has received federal approval from the U.S. Environmental Protection Agency (EPA) for use on potatoes. This new addition to Syngenta’s fungicide portfolio provides growers with a new, user-friendly twin pack of Quadris® and Ridomil Gold® for soil application in potatoes.

With Quadris Ridomil Gold growers receive the benefits of two proven products to protect against all four major classes of fungi and control soil borne disease and storage rots. A single application provides broad-spectrum control of pink rot, Pythium leak, black scurf (Rhizoctonia) and silver scurf.

A combination of systemic fungicides, Quadris Ridomil Gold is taken up by plant roots and moves into the plant thereby preventing disease infection before it starts. Quadris, containing the active ingredient azoxystrobin, is a broad-spectrum systemic fungicide providing activity against Rhizoctonia and silver scurf. Ridomil Gold, a systemic fungicide containing the active ingredient mefenoxam, provides protection against Pythium seedling diseases plus sensitive strains of the storage and tuber diseases Pythium leak and pink rot.

“Growers have been incorporating Quadris and Ridomil Gold into their disease management programs for years,” commented David Laird, Syngenta Crop Protection fungicide brand manager. “With Quadris Ridomil Gold, growers get the same great performance they’ve come to expect in a more convenient package and at an even better value.”

An at-planting application of Quadris Ridomil Gold replaces a 2-spray foliar program for storage rot control with a single application. This up-front application reduces concerns over weather delays later in the season where application timing may be a critical factor and adversely affected by weather delays.
