Abstract
A method for improving the sensitivity of an assay to determine the pathogenicity of a plant root pathogen using a soil amendment is presented. The method involves growing the plant root in the presence of a soil amendment after exposure of the plant root to the pathogen. A method of breeding plants is also provided.
Claims9
A method of evaluating a plant for resistance to a plant root pathogen comprising:
- a) exposing a dissected portion of a root of a plant to a pathogen, wherein the dissected portion of the root of the plant is on a root culturing substrate at least partially covered by a soil amendment selected from:
- cat litter, oil absorbents, grease absorbents, calcined diatomaceous earth, crushed aggregates, and calcined clay for a period of time;
- and
- b) measuring the plant's resistance to the plant root pathogen.
