Dave Rosenberger, retired plant pathologist from Cornell, shared this information about spraying Cueva copper plus Double Nickel biofungicide against shoot blight. Here’s what Dave said:
Fire blight is causing problems across a broad swath of the mid-Atlantic and Northeast.  Dealing with fire blight at this time of year is always difficult.  Penn State Extension just published an excellent article by Dr. Kari Peter that is worth reading (click here). Of particular interest is her comment that Keith Yoder found that applications of Double Nickel plus Cueva (a copper product) helped to arrest spread of fire blight during summer in a test he conducted last year and reported in Plant Disease Management Reports.  Keith applied Double Nickel at 8 fl oz/100 gal of dilute spray plus Cueva at 2 qt/100 gal, and he made those applications at roughly monthly intervals.
If you are going to apply copper, be sure to apply it only during excellent drying conditions.
