Abstract
AbstractAvocado (Persea americana Milll.) holds a pivotal position in global fruit crops, contributing significantly to the economies of tropical and subtropical regions. However, the rising incidence of diseases poses a substantial risk to avocado production. This comprehensive study investigated the disease landscape in Antalya, the largest avocado cultivation area in the Türkiye. A survey of 2537 avocado trees across 11 regions from 2020 to 2021 revealed alarming disease incidences, particularly in the eastern regions of Gazipasa and Alanya. Dieback, branch canker, anthracnose, and soil-borne root rot were identified as the primary diseases affecting tree canopies, twigs, and branches. Morphological and molecular analyzes unveiled a spectrum of pathogens, with Colletotrichum gloeosporioides dominating in the Mediterranean region. Notably, Phytophthora cinnamomi emerged as a severe threat, causing root rot and decline in avocado trees. Fusarium solani and Fusarium oxysporum, known for their association with tropical fruit crops, were identified in the western parts of Antalya. Additionally, we have detected Neofusicoccum parvum, Lasiodiplodia theobromae, and Neopestalotiopsis rosae in collected samples from avocado trees. The identified pathogens exhibited varying levels of severity in branch canker and anthracnose on avocado branches and leaves. Furthermore, pathogenicity evaluations shed light on the potential of these pathogens to induce severe symptoms, emphasizing the urgency for effective control measures. The exploration of cultural and biological control strategies are crucial for mitigating the impact of branch canker, dieback, and anthracnose diseases, ensuring the sustainability of avocado cultivation in the region.
