Land that was not naturally infested in the prehistoric era probably was infested by contaminated seed and plant material before man became familiar with the germ theory. There are a few quarantines in effect that may be helpful in

Resistance to root diseases and soilborne pathogens has played a major role, and in the future, will most likely play an even greater role in the sustained production of agricultural crops.

Quarantine regulation concerning plant material, soil, and seed may help prevent the spread of other soilborne pathogens, but there has been little research to determine whether or not such quarantines
