Mighty Mustard®: From our family farms to yours
All Mighty Mustard® varieties were bred conventionally by Dr. Jack Brown, Professor of Breeding and Genetics at the University of Idaho. Mighty Mustard is grown and distributed by Pacific Northwest Farmers Cooperative, a family of farms based in Genesee, Idaho.

Plants are a lot smarter than people.
Dr. Jack Brown
Kodiak, Pacific Gold and White Gold all contain high levels of glucosinolates. These chemical agents, found in all brassicas, deliver a deadly punch to many soilborne pathogens, nematodes and weeds. Some chemical companies incorporate a synthesized version of glucosinolates into pesticides and fungicides. But as Dr. Brown says, “Plants are a lot smarter than people.”
Mighty Mustard® delivers multiple soil-building benefits that chemical treatments can’t. Because it’s all-natural cover crop seed, Mighty Mustard® isn’t always as effective as chemical treatments. But if you’re interested in working with nature instead of against it, Mighty Mustard® is what you’re looking for.
