We have small flies on our grape leaves. We have about 1/3 of an acre and so far about 5 plants are infected. Can you recommend a soap mixture that would get rid of the flies and not hurt the grapes?

I sug to mix 1 teaspoon of liquid soap to 1 quart of water, in a spray bottle.I get them at Dollar store for a dollar, if that's not strong enough add more soap, good luck.
"Liquid soap" meaning something like Ivory soap, not harsh dish detergents. I use Dr. Bronner's liquid soap which can be found in some health food stores, supermarkets, or drug stores.
Your "flies" I imagine are Whiteflies. You could also just purchase and organic product like Safer's insecticidal soap and not chance using regular soaps that that can burn leaves once exposed to sun.

Check with www.Jerrybaker.net. He gives you recipes for tonics for pests in the garden, as well as other issues. Most of the ingredients you already have in your home, so the cost is reasonable. I purchased a 20 page phamplet from him more than 25 years ago and had such great success, that I have purchasd several other books.
