It's back again, the dreaded asparagus beetle and their grubby offspring. Over the years I've sprayed, put up physical barriers, encouraged ladybirds and their larvae, picked and squished. Spraying is most effective, provanto, but not kind to other biologicals though.
I've seen asparagus beetle nematodes advertised this year, through dragonfli. I'm going to give them a go but wondered if anyone else has tried them and has any tips or success / failure stories
Thanks in advance
Chris
