Coryneum canker caused by Seiridium cardinale (Coryneum cardinale) was observed for the first time in Israel in 1980 on native cypress trees (Cupressus sempervirens var. stricta and var. horizontalis). Since then, the disease has been recorded in various parts of the country, most often on trees grown in or near irrigated gardens. Lesion development on branches of garden-grown trees was markedly slower when they were inoculated in late summer than in late winter or spring. High relative humidity and bark maturity enhanced artificial infection of nursery seedlings.
