Question natural fungicides?

I have a large row of red tip photinias(N.Texas) that regularly experience black spot/fungal diseases. I'm wondering if there is a natural/homemade/cheaper
fungicide recipe available for spraying .
Weekly spraying can be costly !

My opinion is that the best treatment for the problematic, disease-prone red-tip photinia is a chain saw. I dislike plants that require constant attention, treatment, and such. It is rare to see a stand of them that has not died back periodically from these ailments.

Some informative sites:

Hope this helps.

Thanks ,I generally like the plant,provides a nice barrier . I agree ,it has fallen out of favor !
It looks like I need a little more P and K per one article.
I did a google search and found many links to "natural" choices.

To control fungal diseases, such as powdery mildew and black spot, mix one teaspoon of baking soda in one quart warm water. Add one teaspoon liquid dishwashing soap. Apply to leaves as a spray or drench the leaves of smaller plants with a watering can. Possibly this will help.
Good Luck
