I've tried all the bio remedies- parasitic flies of various species and
ladybirds. Now I'm facing millions of the greenflies- the air is thick


Are you sure they're greenfly? Most of them don't fly - they only have a
few flying individuals for dispersion. "Air is thick" sounds more like
whitefly, of which I too have a mega-infestation.

and
they are swarming over everything, tomatoes, courgettes, cucumbers, herbs,
and fruit has pretty well stopped growing. I've been a committed organic
gardener for years- but this has got beyond a joke- any tips? It is a
large
greenhouse- 18 feet by 10, full of plants.

No, definitely greenfly. I'm an entomologist. There are lots and lots of
flying adults- but millions upon millions of larvae. I've never seen such a
bad infestation. I've spent a fortune on bio remedies- now I'm pointing
towards the chemical shelf at the local garden centre.
