Occurrence of Melampsora euphorbiae on Euphorbia lagascae in south‐east Spain

Abstract

Melampsora euphorbiae (Schub.) Castagne is reported for the first time on Euphorbia lagascae, a spurge which is a native of south‐east Spain and has seed oil rich in vernolic acid. In Spanish trials, rust caused by M. euphorbiae was the major disease of this potential crop.

Melampsora euphorbiae, a new rust disease found on Euphorbia rigida in Turkey

“…E. rigida is also planted in Europe as a garden ornamental, but there are no known records of rust infection. The rust has been recorded previously on E. lagascae in Spain (Villalobos & Jellis, 1992) and E. esula in northern China (Wang et al ., 1994). The fungus has been screened for use as a biological control agent against the weeds E. esula and E. cyparissias in the USA (Bruckart & Dowler, 1986).…”
