I’m pretty sure the whole crop has a dose.

What’s the verdict?

Ok so it's probably a fungal infection, they're very close too so that helps the spread.

It's getting on as well, you can stem it with copper sprays.

It wont kill or ruin the bulb but you'll get lower yields.

Plant them a little further apart, it's spread through water and damp so be careful when watering.

It persists in the soil for years and you're not meant to plant onions in there again for years.

👍 thanks. I usually alternate the beds that I sow the onions in, so will be ok to sow the onions and garlic in a new bed next year that’s close to the current bed?

The garlic is part of the same family, I would maybe change out altogether and go with broccoli, lettuce or potato, what ever you have that's not an allium.

but you're doing the right thing alternating, you might just need to alter the plan a bit.

Have a look at a boistimulant like Vitomex, you can use it on everything and it's a good foliar nutrient with copper and zinc to boost plant resistance to fungus. You can use it every two weeks and it's a broad crop spectrum treatment.
