- About 90% of Peru's ginger production occurs in the Junín region, where suitable conditions for growing ginger plants are found.
- In March 2024, a significant portion of ginger plants in Junín showed severe disease symptoms, including yellowing and necrosis, leading to water and nutrient transport issues and potential plant death.
- Culturing diseased tissue revealed Ralstonia solanacearum species complex (RSSC) as the cause, confirmed through PCR methods, and isolates indicated characteristics of biovar 3 and phylotype I, with DNA sequences submitted to GenBank.
Article Synopsis
- Post-harvest diseases like fruit crown rot in bananas are mainly caused by two fungi: Colletotrichum gloeosporioides and Lasiodiplodia theobromae.
- A study conducted in El Oro province involved collecting banana hands and observing disease symptoms, where ten hands showed initial signs of fruit crown rot during postharvest processing.
- Pathogenicity tests identified a single fungal isolate (C1) as responsible for causing disease in banana crowns, showing distinct mycelium growth and symptoms on inoculated fruits over a 20-day incubation period.
