from that link..............

The purchaser and/or end users are responsibile for ensuring that these products are used in line with industry Approved Codes of Practice. All operators must be trained and certificated in using and applying any Ministry Approved professional product.

If you have not got the necessary certification it would be illegal to use it.

Ah, i guess i won't be doing that then.
If i use it with a watering can would that make it legal, or am i being silly?

[mumofstig]

Still illegal without a certificate 

Just buy some from a garden centre

OK, will do. If you hadn't have told me i would have bought it :s
