Steinernema carpocapsae

[Mikey]

Has anyone used this nematode on cabbage white butterfly, and how successful has it been.

I'm not precious about gardening organically but I'm fully aware that adding or removing anything from the eco system can have detrimental affects.

I don't cover my brassicas and to be honest I'm not that keen on seeing swaythes of enviromesh all over allotment sites, but I don't have the time to patrol daily for caterpillars.

So is this a positive solution or a negative one?
