摘要

In February and November 2002, a severe outbreak of a foliar disease was noted in the main producing Swiss chard (Beta vulgaris var, cicla) areas in the Hatay province of Turkey. In this region, disease was observed in 90-95% of fields inspected Symptoms began as small circular, light brown spots with definite dark brown border on both sides of the leaf. The circular spots increased in size (up to 4-6 mm in diameter), developing into depressed lesions, which were brownish in colour and bordered by a purple margin. As lesions matured, the centre of the spots became whitish grey to black, due to the production of conidia and conidiophores.
