fungicide - edible plants
 

Can someone advise me on a fungicide for edible plants (courgettes). My
plants suffer badly from powdery mildew (or at least they did last year).
All the spray fungicides in the shops seem to be systemic & cannot be used
on vegetables etc.

Help please ?

Thanks

I think there are varieties that are resistant to powdery mildew. They
sometimes state this on labels from garden centres and on seed packets
e.g. from mr fothergill's:
Cucumber 'Marketmore' (code number 715). I have seen resistant
varieteies from other seed supliers as well.

Powdery mildew seems to be more of a problem when the plants are under
water stress. Try watering more generously and more regularly and see if
that cures the problem before resorting to chemical means. Also consider
whether you really need to eradicate it - is it significantly reducing
yields? If not, removing badly affected leaves may keep some level of
control on the problem.
