Mustard Seeds - Nemagon
Nemagon is a natural bio-fumigant for root-knot nematode.
What is bio-fumigation? Well, there are a lot of big words and some fancy jargon, but it condenses down to this: Bio-fumigants are plants that, when grown, then chopped or mowed and tilled into the soil, release a compound that suppresses certain diseases and/or pests. Nemagon has higher levels of this compound than other mustards.
