Isolation And Identification of Common Fungal Pathogens Invading Sweet Potatoes (Ipomoea batatas) Sold in Choba Market, Port Harcourt, Nigeria

This research was aimed at isolating and identifying common fungal pathogens invading sweet potato tubers. Tubers were collected from Choba Market, Port Harcourt in Obio/Akpor Local Government Area of Rivers State. Fungal isolates morphologically identified. The Deoxyribonucleic acid the most isolates, SP-1 SP-2 molecularly characterized using Internal Transcribed Spacer 4 5 molecular markers. sequence aligned Basic Alignment Search Tool for Nucleotide 2.8.0 version National Centre Biotechnology Information database. weight 573 base pairs Lasiodiplodia theobromae 521 Pichia kudriavzevii. Based on similarity, it observed that tubers isolate 99.25% identical to 99.70% These findings showed kudriavzevii are some causal It is projected this result will provide information disease control approach improving post-harvest losses potato. study improve available aid reducing deteriorating activities fungi Sweet Potato
