I visited The Botanical Gardens of Wales earlier this year, really enjoyed it, had a nice chat to the head gardener who told me he use Dipel on all brassicas to keep the dreaded cabbage white off, now this sounded really good to me.
I have searched and searched and although I have found it it's over £50 to purchase :o :o has anyone else any experience of either using or buying this and finding a cheaper source?
I just checked the PSD Pesticides Register and there are no products with the active ingredient bacillus thurigensis var. Kurstaki approved for amateur use and only one for professional use, which is probably the one you found.
Thanks Ceres, at £54 I think I have to give it a miss :'( :'( :'(
