Occurrence and Characterization of Phyllosticta plantaginis

During 2009 to 2011 in southeastern Poland the species Phyllosticta plantaginis was isolated from leaves of ribwort (Plantago lanceolata L.) showing the symptoms of small, regular, necrotic spots. Six isolateswere randomly chosen from the fungus population and their morphology and conditions for growth and sporulation were studied .In addition, the growth of isolates was compared on seven different agar media at 24°C. The temperaturerange of 16°C to 28°C was considered optimal for the growth of this fungus; 20°C to 28°C was the optimal for the formation of pycnidia and conidia.
