| Abstract | ||
| This study was aimed, for the first time isolation and identification of the most important black foot disease causal agents in Nineveh grapevine nurseries. The isolation from diseased grape young plants showed that there were the fungi: Cylindrocarpon destructans (Zinssmeister) Scholten, and it‚s telomorph Ilyonectria radicicola (Gerlach and L. Nillsson) P. Chverri and C.Salgado, comb. nov.; C. macrodidymum Halleen, Schoers and Crous, Campylocarpon fasciculare Schroers, Halleen and Crous, Campyl. pseudofasciculare Halleen, Schroers and Crous, as the main causal agent of disease . Isolation for C. destructans fungus gave the highest percentage from diseased grape young plant root (16.17%) and stem (17.07%). The fungi C.macrodidymum, Campyl.fasciculare, Campyl. pseudofasciculare, and I. radicicola (Telomorph for C. destructans) were recorded for the first time in Iraq. The Pathogenicity test proved to be that all fungi were pathogenic to grapevine cutting (cvs. Shadasoda, local seedless and hallawanii) causing black foot in nursery while the highest disease severity caused by C. destructans on three cultivars. | ||
