Where the heck did you get that from, Robert, it was banned years ago except under special licenced conditions.

Bet you've got creosote stashed somewhere, too, haven't you?!
To answer your question, in the (hopefully) small quantities you have used it will be safe to eat your cabbages. However, if you read up on its properties, you will see that it is highly toxic to birds, fish, and, of course, insects. It is mainly used, under licence, as a post-harvest protector against insect damage. Symptoms of exposure are nausea, dizziness, confusion (a bit like whisky), and high level exposure is very dangerous, but so is drinking petrol, so don't be too alarmed. I personally wouldn't use it for the harm it does to wildlife, and the few caterpillars and whitefly on the cabbages aren't worth the risk

And for goodness sake don't pour it down the drain. Get it disposed of safely.

It is rumoured that there is a whole container load of Lindane sunk in the English Channel (washed overboard from a ship). If it ever leaks, the experts think it will wipe out all marine life in the Channel.
Hope it is only a rumour. Terrible stuff.

HAHA THANKS FOR YOUR COMMENTS SOMETHING HAS BEEN NIBBLING AT THE CABBAGE AND I DON'T THINK IT'S SLUGS I CAME ACROSS AN OL D BOOK ON VEGETABLES TO SEE WHAT I COULD USE SAFELY AND IT WAS RECOMMENDING THIS

Post harvest protector - on the plants that remain in the ground or the cabbages we are going to eat??

Nah, for grains (rice, maize, etc) against a whole host of beetles and weevils, in storage. Worrying isn't it?

THANKS FOR YOUR COMMENTS

Heavens above, the things they don't tell us.
