When feasible disinfest pruning too

When feasible disinfest pruning tools by swabbing
the cutting blades with a solution of 7 parts rubbing
alcohol and 3 parts water between each cut. Avoid the
use of mulches that promote high moisture around
the plants, and remove tree leaves that cover the
planting in the fall. After the above cultural practices
are completed, fungicide sprays may still be needed in
some cases to prevent further spread of the disease.
