A cure for powdery mildew in the garden?

I saw this just not on craigslist and haven’t stopped to look this up anywhere else. Could this work?

1 tsp baking soda
1 qt of water
a few drops of liquid soap

spray the leaves once a week top and bottom.

We’ll have to see.

Liquid soap does spell doom for aphids. So if you have the bad type of aphids on your plants, a spray bottle filled with soapy water will do. But it also kills ladybugs and other beneficial insects.

  1. The liquid soap is seldom used for its pesticidal qualities, but for its ability to help the other components in the mixture to adhere to the plant.

    Nothing works on those Asian beetles but hand picking. Have a wide mouth water-lined container in one hand as you knock/drop the beetles into the liquid with the other. Let them drown or pour onto hard surface and begin stomping.
