Summary
Korean (Korea Republic) spinach growers reported leaf symptoms resembling a type of downy mildew infection or physiological degeneration. In November 2007, spinach plants showing symptoms of powdery mildew were found in an organic farming garden in Busan, Korea. Initial symptoms were pale greenish, circular discolorations with a white fluffy covering on the upper and lower surfaces. Lesions expanded and coalesced to produce large areas of yellowing and chlorosis, occasionally with a necrotic centre. This is thought to be the first record of Oidiopsis haplophylli on spinach and on Chenopodiaceae.
