Q.How Do I Store A Copper And Horticulture Oil Mix? I Made A Mixture In A Pressure Sprayer And Only Used Half Of It, Can I Store It
in the container and use again in 6months? Will it go bad or start to destroy the plastic container?

You can store these, indefinitely, but not in plastic. This will need to be stored in glass.
