A field survey was conducted in Algeria to assess the state of dieback
in some vineyards and identification the fungal pathogens associated
with necrotic wood lesions. Field surveys conducted during spring
seasons in 2006 and 2012 revealed that an average disease incidience was
25 % , the indice of disease severity varied of 0.5-2%, based on
herbaceous symptoms.
Some sections of wood cultivar, collected from four
localities vine showed many kinds of necrosis, central sectoral(brown
colour), necrosis sectoral(grey colour) and central light brown. Wood
samples were collected and used for isolation and then placed on
potato-dextrose (PDA) medium. The results showed that the presence of
wood fungi mostly affected the vine trunk were isolated and the fungi
were identified morphologically as Botryosphaeria species and
Fomitiporia mediterranea. This articles available at: Volume 4, Number 6, June 2014 – IJAAR
