Abstract
In Basrah, grapevines suffer from dieback. Lasiodiplodia theobromae and Neoscytalidium dimidiatum were isolated from diseased grapevines, Vitis vinifera L. and identified based on morphological characteristics and DNA sequence data of the rDNA internal transcribed spacer (ITS) region. The results of the pathogenicity test conducted under greenhouse conditions for L. theobromae and N. dimidiatum reveal that both species were the causal agents of grapevines diebacks in Basrah, Southern Iraq. A brief description is provided for the isolated species.
Key words: grapevine, dieback, Lasiodiplodia theobromae, Neoscytalidium dimidiatum, internal transcribed spacer (ITS), rDNA, Iraq.
