State
A fungal plant pathogen damages crop or ornamental plants by direct tissue decay, by producing toxins, or both, sometimes causing widespread agricultural loss.
Show
Dutch elm disease, caused by a fungus vectored by elm bark beetles, blocks a tree's vascular system and has devastated elm populations.
Watch for
A fungal pathogen's toxin can damage a crop's quality where the fungus itself destroys little plant tissue.
