The Guide to Seed Treatment Stewardship

What should I do with unused treated seed?

“The Guide to Seed Treatment Stewardship” is the product of industry-wide collaboration between seed companies, seed treatment providers and universities – and it draws from data collected worldwide. Its purpose is to provide farmers and seed companies with critical information and up-to-date guidelines for managing treated seeds effectively to minimize the risk of exposure to non-target organisms – like pollinators, water supplies, and animals.

There’s no question that today’s seed treatments are enabling America’s farmers to realize greater yields, healthier crops and higher revenues than ever.  At the same time, precision seed treatment technology is reducing potential risks to the environment. But like farming itself, there’s a science to using treated seed successfully and in a way that maintains the delicate balance of nature.

“The Guide serves as an all-in-one resource that addresses every stage of a seed’s journey from treatment to planting – but it’s easy to understand and easy for farmers to refer to for answers to specific questions.”
– Andrew W. LaVigne, American Seed Trade Association
