PY - 2020 DA - 2020/07/09 TI - Identification and Pathogenicity of Fungal Pathogens Associated with Stem End Rots of Avocado Fruits in Kenya SP - 4063697 VL - 2020 AB - Losses associated with stem end rot (SER) of avocado fruits have been reported in all avocado growing regions of the world. In Kenya, mature avocado fruits present SER symptoms during storage and marketing, but the disease causal agent(s) has not been established. This study aimed to identify the fungal pathogen(s) associated with avocado SER in Kenya and evaluate its pathogenicity. Fungal isolates were collected from symptomatic avocado fruits from randomly selected orchards and major markets within Murang'a County, a major avocado growing region in Kenya, between September 2017 and March 2018. A total of 207 and 125 fungal isolates, recovered from orchards and major markets, respectively, were identified morphologically and further confirmed by molecular techniques. The identified isolates were Lasiodiplodia theobromae.（39.8％）， Neofusicccum parvum.（24.4％）， nectria pseudotrichia（18.4％）， Fusarium solani.（7.2％）， F. oxysporum.（5.1％）， F. Equiseti.（3.9％），和 坎迪桑那州坎迪姆（1.2％）。 坎迪桑那州坎迪姆被从市场上的水果完全恢复过来。在致病性测试中， L. Theobromae.那 N.Parvum，和 N.Psudotrichia.导致最严重的血症症状。因此，它们被认为是肯尼亚鳄梨果仁欧二鹿果酱的主要病原体。据我们所知，这是肯尼亚鳄梨果实欧丁病原体的第一个报告。鉴于鳄梨果实对家庭收入和外汇的重大贡献在肯尼亚，这一信息很重要，无法进一步制定肯尼亚鳄梨水果采后丧失的管理策略。SN - 1687-918X UR - https://doi.org/10.1155/2020/4063697 Do - 10.1155 / 2020/4063697 JF - 国际微生物学杂志PB - Hindawi Kw - ER -
