“The collaboration between Ceradis and WinField is a testament to both company’s commitment to the future of biotechnology and a shared goal in delivering effective and environmentally friendly solutions to growers,” says Jan Stechmann, Vice President of Marketing and Sales. “CeraMax is what the industry has been asking for while aligning perfectly with WinField United’s BioVerified program.”

CeraMax is a biological seed treatment for the prevention of soil-borne fungal diseases like Rhizoctonia spp and Fusarium virguliforme, the causal agent of Sudden Death Syndrome (SDS). Containing the active ingredient Natamycin, CeraMax empowers the genetic potential of crops to increase early-season vigor for a stronger and more uniform emergence at the start-up of the season.

Registered by the Environmental Protection Agency as a bio-fungicide seed treatment for soybeans, corn, and wheat, CeraMax offers the first-of-its-kind technology with stewardship and seed safety attributes not offered with most synthetic seed treatments. CeraMax also serves as economical alternative to synthetic seed treatments with high return on investment.

WinField United, which has an established track record for bringing innovations to growers, is marketing and selling CeraMax in soybean-producing areas most impacted by SDS.

For the 2024 season, CeraMax is available through WinField United retailer network and Direct Enterprises, Inc., in Westfield IN.
