A foliar disease, causing necrotic spots and severe defoliation of Elaeagnus angustifolia , was detected in Tuscany, Italy, in 1979. The causal agent was identified as Septoria elaeagni. It was not pathogen to E. umbellata, E. pungens, E. multiflorum , and Hippophae rhamnoides. Ultrafiltrates from liquid cultures showed toxicity against E. angustifolia and some herbaceous species, non hosts of the pathogen. Disease was significantly more severe in an overhead irrigation system than when water was delivered to the soil alone.
