Mustard
Brassica nigra
Mustard as a cover crop:
Acts as a natural bio fumigant
Generally winterkills (at 26 degrees F)
Easy to kill with herbicides and tillage
Provides alleopathy weed control
Helps “clean up” problem fields where nematodes are a problem
Hinders the germination/survival of ryegrass and other cover crops…may be used to clean up a problem cover crop ryegrass field
New varieties are superior to VNS or wild mustard for nematode or weed control/suppression
