The fungus was isolated by direct conidia procedure was carried out in aseptic conditions to amplified using Polymerise Chain Reaction (amplified at above 500 bp and results by using primer and bands were observed respectively. nucleotide BLAST analysis showed that ten isolates h blight disease and were deposited in the gene ban nucleotide sequences. The neighbour-joining and boo which makes to be a complex disease.
