Other claims from this paper (10)
- Observation Dark depressed spots up to 10 mm in diameter are recorded on Giant Cavendish banana fruits in Costa Rica.
- Observation Pits first appear in the field, usually on almost mature bananas bunches.
- Association Pits increase in number during cold storage and ripening.
- Association Disease is maximal during and for a short time after heavy rainfall.
- Observation Pyricularia grisea was consistently isolated from typical pits on banana fruit.
- Intervention effect Pitting disease was reproduced by inoculating banana fruit in the field with conidia of P. grisea from pure culture.
- Observation Conidia of the pathogen germinate within 1–2 hr in a film of water on the peel of immature banana fruit.
- Observation The infection hypha is suggested to penetrate the cuticle but not the epidermis cell wall.
- Observation After harvest the fungus invades the epidermis and underlying tissues of banana fruit to cause a pit.
- Observation The symptoms of the banana pitting disease are identical with those described earlier for pitting disease.
