Diamond back moth

Debris netting, which quite a few of us use, seems to keep them out.

Have used enviromesh before but it's very unwieldy to use on such a large area with the blue hoops.  Is debris netting any more pliable? Think I might just give up on tall brassicas at least..

I understand that this moth is immune to pesticides, so you might find them ineffective. Good old soapy water might reduce the caterpillars a bit though.

Bumblejo, debris netting is relatively easy to use. We sewed two pieces together by hand to creat a section wide enough to use over taller brassicas. Here is what we have no (Obviously the green thing, not the fruit cage in the background lol!) The edges are weighted down by planks of wood.

Thanks Sunshineband, that's impressive. How did you build the structure underneath?  May have to have a rethink for next year....

It is 8 metal poles from the sides of an old bunk bed, pushed about 30cm into the ground, with canes along the sides and crossways all held together with cable ties. I did have butterfly netting on it, and this will go back on for the Winter as the debris netting will be too wind resistant the structure might well sag to one side: our site has very high winds in the Winter. The long sides are two overlapping canes secured with, yes ... double helping of cable ties.
Here is a photo of it with the butterfly netting in place, so you can see the Heath Robinson style structure lol. (This is back in May so the plants are quite small)

Thanks for the pic, it looks great.  Will have a go at that next time.  Wonder if anyone I know has got some bunk beds they don't want! We did actually use some of our own made of wood to build shelves in the shed a while back, There are so many ways to recycle stuff on an allotment..

There certainly are!  Fence pins work well as uprights too, as they can be driven a decent way into the ground, but make an enclosure a little short for PSB though. Even this one gets "extended" in the Winter by tall canes with bottles on the end of them to raise the netting at their end. Keeps the pigeons at bay too
