I have a large catoneaster which all of a sudden has been covered in
white fluffy mildew, it will however come off with a high pressure
hose
pipe but reappears days later even worse than before. Is there any
product that can be used to eradicate this unsightly stuff. Any
advice
welcome. thanks chris...

You could try a soil-drench of horticultural oil or Neem oil to bind
the
mildew spores to the soil, otherwise they'll just reinfect the plants
again & again. The leaves of all susceptible plants can be sprayed
with
dilute milk, which works on powdery mildew far better than any
commercial
fungicide (but doesn't work on other types of fungus).

What dilution would you recommend. Is there any preference for the type
of
milk, i.e., whole, 2%, skim ...?

Any kind of milk -- skim is fine -- deluted with five parts water.


Thanks! I am plagued with powdery mildew late in the summer. I assume that
it is best to use it as a preventive treatment rather than wait until the
mildew appears?
