BeneficialDisease ManagementSupported
Horseradish root exudates contain allyl isothiocyanate, a biofumigant that suppresses soil-borne pathogens including Verticillium dahliae and Rhizoctonia solani that affect potato.
Plant horseradish at the corners or ends of potato beds. Keep it contained -- horseradish spreads aggressively.
