Root and crown rot of agaves

Disease Information

Root and crown rot of agaves

Symptoms and damage

Several soil borne pathogens including a species of the bacterium

Erwiniaand the fungus Fusariumhave been implicated in root and crown rots of agaves. Disease is usually in concert with infestations by the agave weevil, and currently it is thought that weevil feeding enables these pathogens to enter and cause disease when they normally would not

be pathogenic on healthy plants.

Management

there is no control for the bacterial and fungal

infections once the microbes have entered the plant.
