I think our allotments have a serious outbreak of this on onions,
shallots, etc. Perhaps it was the weather.

Advice seems rather drastic.
https://www.gardenfocused.co.uk/fruitarticles/pest-disease/allium-leaf-miner.php
says "When the onions have been infested there is no treatment for them,
chemical or otherwise. Remove all parts of the infected plants and burn
them."

I thought I might cut them off at ground level and see what grows back.
Nothing ventured, nothing gained.

Any other suggestions?

In future I will either start growing under fine net, or get them
started indoors, and plant out in May.

Bill

The other line moves faster.
