Abstract
A method for conferring plant tolerance to severe diseases, specifically caused by a viruses vectored by soilborne fungi, wherein a non-virulent or mildly virulent virus is transmitted to the plant and renders the plant tolerant to disease caused by a more virulent virus. The protective virus is transmitted to a host plant via a viruliferous soilborne fungus which is coated onto seed and thereby produces a disease tolerant plant.
