First report of Puccinia hemerocallidis in South Africa
In February 2007, rust symptoms were observed on Hemerocallis spp. plants (daylilies) in a garden near Paarl in the Western Cape Province of South Africa. In November 2007, similar symptoms were also observed on Hemerocallis spp. plants in a garden near Franschhoek. In February 2008, more diseased plants were found in nurseries in Stellenbosch, Buffeljagsrivier and George (all in Western Cape Province). The rust fungus was identified as Puccinia hemerocallidis (EPPO A1 List). It is noted that the alternate host, Patrinia spp. is not endemic in South Africa and apparently not sold by nurseries. This is the first report of P. hemerocallidis in South Africa.
The situation of Puccinia hemerocallidis in South Africa can be described as follows: Present, first found in 2007 in several gardens and nurseries in the Western Cape Province.
