SKU A3289

Author(s) G. L. Worf, J. S. Stewart.

Russian olive (Elaeagnus angustifolia) is a small tree with beautiful, silver-gray foliage. The tree was once a valuable landscape plant, as it is well-adapted to urban environments and tolerates dry summers and low winter temperatures.

In 1974, Phomopsis canker was first confirmed in Wisconsin. Since then, the disease has become epidemic throughout the state, leaving infected trees looking ragged and unsightly and eliminating the Russian olive as a useful tree. This publication describes the disease and offers some ideas to reduce its effects (2 pages; Revised in 1999).
