A soil borne pathogen is a disease-causing agent which lives both in soil and in a plant host, and which will tend to infect undiseased plants which are grown in that soil.[1] Common soil borne pathogens include Fusarium,[1] Pythium,[1][2] Rhizoctonia,[1] Phytophthora,[1] Verticillium,[1] Rhizopus,[2] Thielaviopsis,[2] and nematodes[1] including Meloidogyne.[3][4]
