This is not part of the Orchard Spray Kit, however it can be mixed with the above ingredients for the dormant spray and fall holistic spray if desired. The main reason we offer this form of copper (sulfate pentahydrate) is because it provides effective prevention of peach leaf curl approved for certified organic use. Some folks also use Copper Spray as a fungicide to prevent blight in tomatoes and black spot in roses. Be sure to read the label for dosage and precautions.
