I'm not going to be much help, as my only response is that exactly the
same
happened to me the only time I ever succeeded in growing a turnip or two.


My dad did manage to cut away enough from each one to make a very small
amount of soup, though!


Using Google, I have now found a good deal of advice from an American web
page.http://www.ehow.com/how_5632827_rid-...s-turnips.html
Scrupulous garden hygiene,
Mechanical barriers to prevent the fly gaining access to the root
Do not compost the infected plants
Expensive insecticides - if you can find one you trust not to poison the
family.

And I thought in my innocence, that I could just pop a few seeds in and with
a little water and weeding enjoy nice flavourful stews in the Autumn. Wrong
again!

Not so easy this gardening lark, is it?

Sow some more now, the seed's cheap - 'Milan Purple top' away from
your damaged ones. If the late summer monsoon happens you might just
get some nice turnips. The fly has more than one brood and you can
sometimes get a crop between broods.
