This presentation summarizes common banana diseases caused by fungi, bacteria, viruses, and nematodes. It provides details on the symptoms, causal organisms, disease cycles, and favorable conditions of three key diseases: anthracnose, crown rot, and fruit rot. Anthracnose is caused by Colletotrichum musae and infects young fruits, leading to dark brown spots and sunken lesions. Crown rot, caused by Colletotrichum musae, Fusarium spp. and Botryodipiodia theobromae, causes blackening of the crown tissue and rotting during transportation. Fruit rot is caused by Botryosphaeria ribis and has similar symptoms to anthracn

- 5. Disease name Causal Organism Anthracnose Colletotrichum musae Black leaf streak (BLS) or Black Sigatoka Mycosphaerella fijiensis Brown spot Cercospora hayi Crown rot Colletotrichum musae Damping-off Deightoniella torulosa Fruit rot Botryosphaeria ribis Leaf rust Uredo musae Yellow Sigatoka Mycosphaerella musicola Sheath rot Nectria foliicola Leaf spot Leptosphaeria musarum Fungal Disease
- 6. Disease name Causal organism Bacterial wilt Pseudomonas solanacearum Finger tip rot (gumming) Pseudomonas spp. Rhizome rot Erwinia carotovora Xanthomonas wilt (BXW), Banana bacterial wilt, enset wilt Xanthomonas campestris pv. musacearum Bugtok Pseudomonas solanacearum Bacterial Disease
- 7. Disease name Causal organism Bunchy top Banana bunchy top virus Streak Banana streak virus Bract mosaic Banana bract mosaic virus Banana mild mosaic Banana mild mosaic virus Viral Diseases
- 8. Disease name Causal organism Nematode root rot (burrowing nematode) Radopholus similis Root-knot Meloidogyne arenaria Meloidogyne incognita Meloidogyne javanica Spiral nematode root damage Helicotylenchus multicinctus Helicotylenchus dihystera Nematode Disease
- 9. Anthracnose of Banana Causal organism: Colletotrichum musae
- 10. Symptoms 1. Infects the young fruits at the distal ends 2. Skin turns dark brown to black 3. Lenticular or diamond shaped Fig: Anthracnose of banana
- 11. Ripe fruit Symptom 1. Initially brown spots appear and later become sunken 2. Tip rot may develop and can rot the entire fruit but the pulp is not usually affected
- 12. Disease cycle: 1. Conidia of Colletotrichum musae primarily over winters on dead banana & banana plantation microflora 2. In high humid weather and high temperature(27-300c), infects banana flowers petioles & leaves 3. Spores spread through wind and affect fruit of banana .
- 13. Disease Cycle
- 14. Suitable factors for Anthracnose of Banana 1. High temperature (27-30° C) & high relative humidity 2. Moist and warm weather during the reproductive stages 3. Poor drained soil 4. Wet periods for a long time (12 hours or more)
- 15. Control Measures 1. Clean cultural practices 2. Harvesting at morning because low temperature helps to minimize disease 3. Avoid injury during transport
- 16. Chemical control: 4. Spraying the bunches with 1% Bavistin/ Tilt 0.05% solution or any other copper fungicide 4 times at 15 days interval . 5. Dipping in Mancozeb 0.2% for 2-3 minutes after harvest
- 17. Crown Rot of Banana Causal Organism: Colletotrichum musae Fusarium spp, Botryodipiodia theobromae
- 18. Symptom of Crown Rot of Banana 1. Initially blackening of the crown tissue of the fruit 2. The rot may spread into the crown during transportation 3. Rotting is most noticeable if transport time exceeds 7 days
- 19. Fig: Crown Rot
- 20. Suitable factors for Crown Rot High temperature Poor transport facilities Wet periods for a long time
- 21. Control: Dipping or spraying the harvested hands with 0.05% Bavistin
- 22. Fruit Rot of Banana Causal Organism:Botryosphaeria ribis
- 23. Fruit Rot of Banana Anthracnose of banana and fruit of banana is more or less similar. In the later stage of anthracnose the whole fruit become rotting. It is called the fruit rot.
- 24. Green fruit become rotting in the inner side Pulp of banana become rotting in the ripening stage
- 26. Suitable factors for Fruit Rot of Banana 1. High temperature 2. High relative humidity 3. Moist and warm weather during the reproductive stages 4. Wet periods for a long time
- 27. Control Measures 1. Clean cultural practices 2. Harvesting at morning because low temperature helps to minimize disease 3. Avoid injury during transport
