Broccoli

These are a couple runty broccoli seedlings that I planted out, thought they might pick up once in the ground but now they look like they are infected with something, any ideas what's wrong with them?

Thanks

I would say it's probably the flea beetles http://rhs.org.uk/advice/profile?pid=510

Have a look on your plants and see if you can see any tiny beetles. They jump when disturbed like a flee, which I would imagine is where they got the name from!

I think I can even see one in the first picture, although hard to tell with that resolution.

  Indeed, I should look more carefully. What should I use to get rid of them, that won't hurt the plants, as they are so young? Is it too late to net them?

Thanks
