Although control of Diplodia shoot blight is difficult, damage from the disease can be minimized. Selecting trees with some level of resistance is important. Certain species, such as Austrian pine, are very susceptible, whereas others, such as Scotch pine, tend to be less susceptible. Reducing stress is important in limiting damage. This involves supplying adequate water, particularly during droughts, and maintaining good fertility.
Control insects to limit tree damage and entry wounds for the fungus.
Do not crowd newly planted trees. Give them adequate space for development. Do not locate new plantings and nurseries near older trees which may be infected and serve as a source of spores. Removing or pruning infected branches may improve the appearance of individual trees but may not significantly reduce disease spread. Since new infections frequently are initiated from spores produced on cones, removal of cones can contribute to disease control, but it is tedious and may reduce the ornamental value of the tree.
