Asparagus rust (Puccinia asparagi). This fungus causes reddish-brown warts on the stems. Too moist soil is often the cause.

Affected plants

Remedy

Cut off the affected stems and destroy them.

Prevention

Plant the asparagus in a windy spot: so that the wind has free play between the plants. Make sure the plants don’t dry out or get too much water. After harvesting, remove all plant rests.
