Pruning to reduce overwintering disease inoculum:Removal of infected canes, cordons, trunks, or fruit during dormant pruning can be especially important in the management of Phomopsis Cane and Leaf Spot, Eutypa dieback, and black rot. An understanding of how these pests overwinter leads to the removal in infected tissues, which significantly reduces the primary inoculum available for the upcoming season. This significantly reduces disease pressure and thus, the amount of fungicide needed for management. (From Grape IPM in the Northeast, T. Weigle and J. Kovach, Number 211, 1995)
