At the risk of seeing Mickie bald or having the red font start blinking and hissing, experience with this recipe tells me that, once you have the master solution mixed, you may want to move from the standard 2 TB of the master solution + 1 cup of water to, instead, 2 TB of the master solution mixed with up to 8 cups of water. The mix is, of course, not nearly as strong but, in very high temps, it does not burn the leaves and seems almost as effective. A friend tried the solution full strength in the early evening and cooked the edges of her squash leaves. It got rid of the bugs but now her garden looks unsightly.
