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.
“…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).…”
