Asparagus beetle is the most widespread and damaging pest of asparagus during the summer months. Heavy infestations weaken the plants and cause a poor crop in the following spring.
Both the adult and larval stages of asparagus beetle eat the foliage of asparagus, they can also gnaw bark from stems, causing growth above the point of damage to dry up.
Burn old stems at the end of the year to destroy some overwintering beetles. Hand pick the beetles and larvae from plants when seen from late spring onwards. Light infestations are unlikely to affect cropping in subsequent years.
