I have a vine that is Very badly infected with what looks like powdery mildew. I have purchased Mancozeb Plus Fungicide And Miticide. Should I cut back infected canes and leaves prior to treating?

Thank you for contacting Yates.
For heavy infection, it is best to prune off the most affected leaves and stems before spray thoroughly with mancozeb plus.
