Reply To: Onion thrips on leeks?

Could it be leek moth? I’m in France where the moth causes a great deal of damage similar to your description. There has been discussion about them on this forum, so clearly a problem in the UK too. No part of the lifecycle occurs in the soil. Local friends recommended alternating rows of carrots with leeks, but sadly, that did not help. I’ve found the only solution is to cover my leeks with mesh until the end of September.
