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.
