Re: Fw: Re: What to do for mildew?

Well, Diann, what about the old baking soda formula?  Worked a treat
on my mildewed Phlox....was tested by Perdue (I think it was) for use
on roses for blackspot.

To 1 gallon of water, add:
3 tablespoons of baking soda,
1 teaspoon of horticultural oil
1 teaspoon of dishsoap (as in liquid, like Joy)
Apply every week to 10 days by spraying ... remove infected
leaves.   Also, spray the ground around the plant.

Have also read that cinnamon is an effective fungicide, tho' long
term use can be detrimental to root development.

Have also come across recommendation for using milk as a fungicide.
The following copied from a post I saved from somewhere last June:

"An article in the Oct 16th New Scientist describes the use of
milk as a fungicide to combat powdery mildew.

"Milk's fungicidal powers were discovered by Wagner Bettiol of the
environmental laboratory of Embrapa, the Brazilian Agricultural
Research Corporation, n Jaguariuna, north of Sao Paulo. Bettiol, who
was looking for cheap ways to control plant pests, observed that
byproducts from milk-processing factories killed powdery mildew on
courgettes. So he decided to simply spray fresh milk on the plants to
see if it had the same effect. To his surprise, he found that it did.
In fact, spraying heavily infected plants twice a week with a mixture
of one part cow's milk to nine parts water was at least as good at
stopping mildew as the chemical fungicides fenarimol and benomyl,
Bettiol discovered."

And the following from another save in July of 2000:

"Brazilian researcher Wagner Bettiol has discovered that a simple
mixture of one cup of milk mixed with 9 cups of water and sprayed on
mildew infected plants twice weekly will cure them more effectively
that the toxic fungicides commonly used. Bettiol's conclusion is that
the milk is germicidal and that it may stimulate plant resistance to
fungus and mildew."

I have not tried either cinnamon or milk, but pass these along FWIW.
I have used the baking soda formula with success, as I said, on Phlox
and on Pulmonaria.
