How do you control anthracnose in bananas?
Chemical fungicides, like imazalil, are commonly used to control anthracnose in bananas during the postharvest period in order to prolong the shelf life of fresh fruit.
What is the scientific name of banana?
MusaMusa / Scientific name
The first scientific term given to banana is Musa paradisiaca Linn. published in 1753 by Linnaeus in his book Species Plantarum, the origin of modern botanical nomenclature.

What is banana wilt?
Share. Banana Bacterial Wilt is a disease devastating East African Highland Banana crops.

What does crown rot look like?
Signs of Crown Rot Disease Infected areas may be discolored, usually tan or dark colored, which is indicative of dead tissue. As crown rot progresses, the plant will begin to wilt and quickly die, with younger plants being more susceptible to death. Foliage may yellow or even turn a red to purplish color as well.
How do you prevent crown rot in bananas?
Crown rot is controlled commercially by submerging hands or clusters of banana in fungicides solutions. Conversely, fungicide treatment is not acceptable to consumers of non-chemical bananas which encouraged banana processors and researchers to look for alternative methods of postharvest disease control.
What are the characteristics of anthracnose?
Anthracnose disease is induced by the fungus Colletotrichum lagenarium, and the characteristic symptoms include small, yellowish watery spots that enlarge rapidly to become brownish. Oblong lesions then develop on the stems often resulting in death of plants. On fruits, round black sunken cankers occur.
How do you identify anthracnose?
The symptoms of anthracnose are easier to identify once the tree has leafed out. You’ll notice small, circular or irregularly shaped dark or brown dead spots on the leaves, dead leaf margins and tips, and large dead blotches along the leaf veins or in-between the veins.

Are banana fruits resistant to Colletotrichum musae?
Virulency of some Colletotrichum musae to banana fruits and resistancy of some banana cultivars fruit to Colletotrichum musae. In: Indonesian Journal of Plant Protection, 1 (1) 33-37.
How many Colletotrichum isolates are found in anthracnose lesions of banana plants?
Thirty-eight Colletotrichum isolates were encountered in anthracnose lesions of five local banana cultivars, ‘berangan’, ‘mas’, ‘awak’, ‘rastali’, and ‘nangka’. Based on morphological characteristics, 32 isolates were identified as Colletotrichum gloeosporioides and 6 isolates as C. musae.
What is Colletotrichum musae?
Colletotrichum musae was isolated from dark-brown anthracnose lesions on commercial banana (Musa sapientum L.) to establish the causal agent of the symptom. The fungus grew fast and produced white aerial mycelium on PDA.
What is anthracnose in bananas?
Anthracnose is one of the leading causes of quality losses in banana fruit. It is caused by several species in the genus Colletotrichum. In the Philippines, Colletotrichum musae has long been known as the only anthracnose pathogen of banana in the Philippines, but molecular characterization is yet to be done.
