Abstract
The present embodiments generally relate to methods of non-destructively imaging plant root damage by insect root herbivores and evaluating the efficacy of insecticidal materials associated with the roots of plants against the insect root herbivores, useful for automated high throughput bioassays.
Claims25
A method of non-destructively determining the resistance of candidate plant roots to insect herbivory, comprising subjecting root tissue of the candidate plant comprising at least one insecticidal material associated with said root tissue to at least one insect root herbivore, obtaining a non-destructive image of roots of said candidate plant, wherein the candidate plant roots are substantially embedded in the soil, and determining the resistance of the candidate plant roots to insect herbivory based on injury to the root tissue.
A method of non-destructively assaying the efficacy of an insecticidal material to insect root herbivory, comprising subjecting root tissue of a candidate plant comprising at least one insecticidal material associated with said root tissue to at least one insect root herbivore, presenting the candidate plant to a non-destructive imaging apparatus, obtaining a non-destructive image of roots of said candidate plant, and generating a root nodal injury score.
