Cadophora luteo-olivacea has been reported as an emerging postharvest pathogen of pome fruit and kiwifruit with the potential to have a significant economic impact. To date, the biology and epidemiology of C. luteo-olivacea has been poorly investigated. Therefore, the present study aims to gain knowledge on C. luteo-olivacea biology, by analyzing the parameters that can influence the fungal growth and virulence and by getting information about the sensitivity to fungicides. A mycelial growth study at different temperatures was conducted with five C. luteo-olivacea isolates belonging to different host plants (apple and kiwifruit). The optimum fungal growth was observed in a temperature range between 20 °C and 25 °C, with C. luteo-olivacea isolates from kiwifruit that resulted in faster growth than apple isolates. The pathogenicity of C. luteo-olivacea isolates was evaluated on detached apple and kiwifruit twigs, on 'Golden Delicious' and 'Fuji' apples, and on 'Hayward' and 'Sungold' kiwifruit, stored both at 0 °C and 20 °C. The pathogenicity on fruit and on woody twigs was variable, depending on the host cultivar, with a minor effect related to the fungal isolate. Moreover, the efficacy of ten different plant protection products (PPPs) against the conidial germination of the isolates was determined. Few PPPs were found to be effective (e.g. fludioxonil, dithianon, and cyprodinil) against C. luteo-olivacea. These results represent a starting point for further research on the biology and epidemiology of C. luteo-olivacea and the development of effective management strategies.

据报道，Cadophora uteo-olivacea是一种新出现的仁果和猕猴桃采后病原体，有可能产生重大的经济影响。迄今为止，对C. uteo-olivacea的生物学和流行病学的研究还很少。因此，本研究旨在通过分析影响真菌生长和毒力的参数以及获取有关杀菌剂敏感性的信息，获得有关C. uteo-olivacea生物学的知识。对属于不同寄主植物（苹果和猕猴桃）的五种黄橄榄分离物进行了不同温度下的菌丝生长研究。在 20 °C 至 25 °C 的温度范围内观察到最适宜的真菌生长，从猕猴桃中分离出来的C. uteo-olivacea比苹果分离物生长得更快。在 0 °C 和 20 °C 储存条件下，对分离的苹果和猕猴桃嫩枝、“Golden Delicious”和“Fuji”苹果以及“Hayward”和“Sungold”猕猴桃评估了 C. uteo-olivacea 分离株的致病性。对水果和木本树枝的致病性各不相同，具体取决于宿主品种，与真菌分离株相关的影响较小。此外，还确定了十种不同的植物保护产品（PPP）对分离株分生孢子萌发的功效。很少有 PPP（例如咯菌腈、二噻农和环丙环胺）对C. uteo-olivacea有效。这些结果代表了进一步研究黄花橄榄的生物学和流行病学以及制定有效管理策略的起点。
