Cornwall UK.(50N 5W)300ft.

I tried hydrogen peroxide at 875 ppm.
I saw a referance to zerotol that said the dilution rate was 1/300 and worked back from that.
It also said something like zerotol contains minimal surfactant for use on waxy or hairy leaves I think pumpkins would come under that category and that it wouldn't need an additional one.
H2O2 seems to have killed powdery on the newly infected areas not so sure about the established areas though.
The idea of spraying three times in 24hours might fix this.

I found some medical research into disinfectants containing H2O2 + Peracetic acid and it said that the H2O2 was better at killing spores and the peracetic acid was better at killing bacteria.

Also do not mix H2O2 with Sulphuric Acid as it can cause spontaneous human combustion.You don't want to do that do you.

lol hahahaahah
perhaps add it to something that the o will bind to and wash into the roots. something nonreactive,etc,,,,,.
i wonder what the natural defences of AGs are??? they fare better than howdens.yet the howdens have stout solid stems.

That mineral oil is just a warm fuzzy way of saying "petroleum distilates". Or Horticultural spray oil by another name.
