Searching for answers

Understanding Mighty Mustard’s® full potential as a biofumigant is an ongoing process. As one university researcher shared with us, “There’s a lot that we still don’t know.”


The nature of science

Researchers from around the country have conducted studies focused on Mighty Mustard’s® various biofumigation properties. While the mustards were effective in lab studies, some researchers weren’t able to duplicate the results in the field. For example, researchers at Kentucky State University and the University of California successfully reduced sclerotinia using isolated concentrations of IdaGold and Pacific Gold’s glucosinolates in lab experiments, but were unable to duplicate the results with Mighty Mustard® cover crops grown in outdoor test plots. Why? Researchers believe the concentrations of glucosinolates in the lab tests were far higher than those typically found in an average Mighty Mustard® cover crop.

"Replenish your soil"

"I am a great advocate for crop rotation and the importance of replenishing the soil with cover crops whenever possible."

"Mustard is an excellent cover crop/green manure because it is a fast germinating seed."
