Leaf blight was observed in anthurium crop in Tamil Nadu and Kerala states of India during 2011-2012. Initially, the symptoms were small circular to irregular brown spots with concentric rings on the leaves that gradually enlarged. Fungal isolates, obtained from infected leaf tissues were grown in pure culture and on the basis of cultural and morphological characteristics and ribosomal DNA spacer sequences, the organism was identified as Alternaria alternata (Fr.) Keissler. To our knowledge this is the first report of Alternaria leaf blight disease in Anthurium andraeanum in India. | Nội dung Text First report of alternaria alternata Fr.
