Abstract

False mildew is a serious disease of safflower crops in the Yaqui Valley, Mexico, and is
caused by infection with a fungus belonging to the genus Ramularia. In the present study, a fungus
isolated from leaf lesions was grown under different growth conditions in order to study its
mycelial growth and spore production, determining that the solid medium of Septoria tritici at
18 °C of incubation and photoperiod of 12 h light-dark, were the most suitable conditions for
the fungal development. The isolated was morphologically identified as Ramularia
cercosporelloides, but genomically as Cercosporella acroptili, therefore cannot be concluded
which species causes this disease. Also, in the periphery of false mildew were found the presence
of Alternaria tenuissima and Cladosporium cladoporioides
