A new Leek pest?
 

Last year was when we first noticed it on a few plants but this year it's
much worse affecting the whole crop and those of fellow allotment holders on
our site. The white flesh of the leek , the bit you eat, has reddy coloured
streaks running right down inside it to the base, on closer inspection
something has tunnelled down the white flesh eating it as it goes and
leaving this reddy coloured stain. Removing all the damaged white leaves
means you end up with a tiny central section to eat.
This is not Leek Moth as we have had that pest for many years here, this is
something new and much more damaging.
I have asked the RHS Wisley for advice on what this is and control (some
hope!).
