What is the recipe for spraying copper on tomato plants to stop blight?
Hello, my name is Greg.

You will mix 2-3 teaspoons of copper sulfate to a gallon of water. You will want to make about 1 gallon for every 10 tomato plants.

Be sure to use the spray mist setting on the spray bottle and spray from bottom to the top of the plant.

All the best in your gardening.
