Do you have a home made recipe for soap shield that is safe to use on plants to control certain insects? I think that it is made with ivory liquid.

The recipe for Insecticidal soap is 1 teaspoon of real soap, not a detergent, in 1 quart of water. You only need about 1 percent soap solution to be effective and you do not need oil or anything else. What makes the insecticidal soap effective is the fatty acids from the animal fats the soap is made from which is why you need real soap and not a detergent. Those fatty acids dissolve the targeted' insects exoskeleton which is what dehydrates it.
