Black sigatoka is a leaf-spot disease of banana plants caused by the ascomycete fungus Mycosphaerella fijiensis (Morelet), also known as black leaf streak. It was discovered in 1963 and named for its similarities with yellow Sigatoka, which is caused by Mycosphaerella musicola (Mulder), which was itself named after the Sigatoka Valley in Fiji .
In plants affected by Fusarium, yellowing and wilting of the leaves typically progresses from the older to the younger leaves. [22] The wilted leaves may also snap at the petiole and hang down the pseudostem. In plants affected by Xanthomonas, the wilting can begin with any leaf and the infected leaves tend to snap along the leaf blade.
Colletotrichum musae is a plant pathogen primarily affecting the genus Musa, which includes bananas and plantains. It is best known as a cause of anthracnose (the black and brown spots) indicating ripeness on bananas.
Fusarium oxysporum f. sp. cubense (Pronunciation ⓘ) is a fungal plant pathogen that causes Panama disease of banana (Musa spp.), also known as Fusarium wilt.The fungi and the related disease are responsible for widespread pressure on banana growing regions, destroying the economic viability of several commercially important banana varieties.
Mycosphaerella musicola was first reported from Java in 1902 and by 1962 was found in most banana growing regions of the world. Although it is spread over short distances by conidia and ascospores, over long distances it is the movement of infected germplasm such as diseased leaves and suckers that is likely to be responsible.
Sometimes it helps to give the plant's pot a quarter-turn every week or so to straighten out its growth, but the better option is to increase light exposure. 5. Losing Variegation or Fenestration
"Segmented Banana" Chilling injury to fruit One of the less common plantain diseases is exostentialis clittellus referred to by most plantain and banana farmers as "segmented banana". This is a result of the peel forming tiny inter-fruit membranes which cause the banana to appear as though it has been sliced before it is peeled.
