I mixed 3 tbsp of Dawn in one gallon of water plus a rounded tablespoon of cayenne pepper. Sprayed all the tomato fruits in the big garden. The intent is to scare off stink bugs sitting on top the fruit and poking holes in it.
I mixed more Liquid Copper at 2 tbsp/gallon and sprayed all the tomatoes in the big garden and the herb garden.
Depending on how the plants react, may add garlic powder to the mix.
