Copper Spray?

[Grow 4 Food]

Someone suggested copper spray for tomatoe plants. Anyone know where to get it and what the best application is? I have checked a couple greenhouses but not having much luck in finding it.

Although copper spray can help with a lot of different situations there are usually better options. What is the exact problem you're having?

Planet Natural is a good source for coppers and other sprays.

My understanding is that copper spray is suppose to help with tomatoe getting a blight as they get farther along. But also the way I took it was that it needed to spray the plants very early for it to do any good.
