There are a number of advantages to using Oxidate instead of Captan fungicide. First of all, you can use it all through the growing period without worrying about stopping use before the harvest. You can also use it on organic crops since it is approved by both the EPA and the OMRI. It is effective not only against fungus, but also against many other diseases that might affect your crops. There is no mutational resistance to Oxidate either, which can make it more effective in treating the diseases that are affecting your crops. It is even exempt from pesticide residue regulations.
