Determination of fungal and bacterial disease agents of apricot trees growing in Hatay province
Fungal and bacterial diseases occur widely and pose serious impacts on apricot (Prunus armeniaca L.) production in Turkey. A disease surveys were conducted to identify the fungal and bacterial causal disease agents associated with root and foliar diseases in the main apricot orchards in Hatay province. The disease agents were isolated from the root, stem, leaf and fruit of infected trees. The results of fungal isolations from diseased apricot roots taken at regular intervals over the entire growth period have indicated that Rhizoctonia solani Kühn. [Rhizoctonia root rot], Verticillium dahliae Kleb. [Verticillium wilt] and Macrophomina phaseolina (Tassi) Goidanich [Charcoal rot] were the most frequently encountered and widespread soil-borne fungal disease agents identified on wilting and dying trees growing in all locations. Majority of the diseased trees were infested by the more than one disease agents. Wilsonomyces carpophilus (Lév.) Adask., J.M. Ogawa & E.E. Butler [Shot hole], Botrytis cinerea Pers. [Gray mold], Podosphaera pannosa var. persicae (Walls.) de Bary [Powdery mildew], Sclerotinia sclerotiorum (Lib.) dBy. [Green fruit rot], Monilinia fructicola (G. Winter) Honey [Brown rot], Cladosporium carpophilum Thüm. [Scab], Alternaria alternata (Fr.) Keissler [Alternaria leaf spot] were the most frequently observed foliar and fruit fungal disease agents. Bacterial disease agent Pseudomonas syringae pv. syringae (Burk.) Young, [Bacterial canker] were also isolated from leaves and fruits of apricot plants with minor importance in the region.
