I did a google search and here is what I found:

Garden Cure-All Tonic
At the first sign of insects or disease, mix up a batch of this Tonic to set things right.

4 cloves of garlic,
1 small onion,
1 small Jalapeno pepper,
1 tsp. of Murphy's Oil Soap,
1 tsp. of vegetable oil, and
Warm water.

Pulverize the garlic, onion, and pepper in a blender, and let them steep in a quart of warm water for 2 hours. Strain the mixture and further dilute the liquid with three parts of warm water. Add the Murphy's Oil Soap and vegetable oil. Using my Weed Sprayer, mist-spray your plants with this elixir several times a week.

Powdery Mildew Solution
Many plants are susceptible to powdery mildew, especially during times of high humidity or constant rain. An effective treatment for controlling powdery mildew is to mix 1 gallon of warm water with 3 tablespoons of baking soda and 1 tablespoon of Murphy's Oil Soap. Mix all ingredients well and spry the effected plants with the mixture on both sides of the leaves. Spray every 7-10 days until the fungus has completely disappeared.

There are more. Do a search and you will see.

Thanks plantynut.

Anyone else have some recipes?

Has anyone found the Murphy's Oil soap recipe for powdery mildew? I've been trying to find it...

Umm, Victorian Bellefonte, Plantynut provided one in his post above. :)

The other day in the grocery line, a lady asked me what I was going to do with the Murphy's I was buying.

"Spray my gardenias for whiteflies."
