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). If the fungus
cannot first of all be be sprayed off entirely or wiped off by hand
without leaving damaged leaves, then the plants have to be cut back to
start over, & treated with dilute milk as they develope.

Good air circulation through the plants is also necessary. Powdery mildew
especially likes areas where plants have gotten overcrowded, & when plants
are stressed by such things as droughtiness, sun-stress, overcrowding.

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?
