Biological control and cross infection of the Neofusicoccum spp. causing mango postharvest rots in Spain. Guirado-Manzano, Lucía Tienda Serrano, Sandra Gutiérrez Barranquero, José Antonio De-Vicente-Moreno, Antonio Cazorla-López, Francisco Manuel Arrebola-Díez, Eva María Frutas - Almacenamiento - Enfermedades y daños Mangos - Enfermedades y plagas Hongos fitopatógenos Mango is one of the main subtropical crops growing in southern Spain. Spanish mango fruit production can be efficiently transported to the rest of Europe, and these mangoes are very appreciated for their quality and flavour. However, postharvest rots have been detected in stored mango fruits, making their commercialization difficult. The causal agents associated with such rot symptoms have been isolated and identified. Because the mango crops used to share the same growing area with avocado crops, fungal presence on surrounding asymptomatic avocado fruits was also analysed to detect potential cross infections. Artificial inoculation with Neofusicoccum parvum and N. mediterraneum was able to reproduce rot symptoms in mango but was also able to induce rots in avocado fruits. To approach a biological control strategy against these rot-producing fungi, two very well-known antagonistic biocontrol bacteria, Pseudomonas chlororaphis PCL1606, and Bacillus velezensis UMAF6639, were tested. The obtained results revealed that both bacteria can control the fungal rots on stored mango and avocado fruits under controlled conditions. Additionally, the strain B. velezensis UMAF6639 showed the ability to persist on the fruit surface of adult commercial trees in experiments under open field conditions, helping to prevent the appearance of these postharvest diseases. 2024-04-10T10:54:37Z 2024-04-10T10:54:37Z 2024-04-10T10:54:37Z 2024-02-11 journal article Guirado-Manzano, L.; Tienda, S.; Gutiérrez-Barranquero, J.A.; de Vicente, A.; Cazorla, F.M.; Arrebola, E.
