Can I mix Captan fungicide with liquid Liqui-Cop copper fungicide. I've read that such a mix helps reduce pest resistance.
Per the manufacturer, it is not recommended to mix Bonide Captan Fungicide and Bonide Liquid Copper Fungicide Concentrate together. If you need to use both products, the manufacturer recommends 48 hours between applications.
