Hi I have had a wonderful year on my allotment,as regards crops.With only
one failure,namely my leek crop.
I raised from seed 2 varieties,as usual one early and one winter.
Both crops were doing well until recently,When I got a bad attack of Rust,
Likewise there is a small grub burrowing into some of the leeks.(It is not
Onion Fly)
These leeks look tatty as regards foliage but good white stalks underneath
if you watch out for the Grub.
Any advice?

Lots of wood-ash in the ground seems to keep the common pest diseases at
bay. I seem to recall that exhibition growers used to use soot and may still
do so, but that is obviously bad if the leeks are for consumption.
