When pests attack banana plant it destroys the crop. It can either make the plant dead, or infest the plant and the fruit it bears. These possible effect can lead to spread of disease.
What is the pest and disease of banana?
The banana aphid is a serious pest of banana due to its ability to transmit banana bunchy top virus (BBTV). Aphid excretion of “honeydew” provides a nutritional substrate for sooty mold fungi, which affects fruit quality and physically block photosynthesis. Banana aphid populations are often tended by ant species.
What might be the effects to the banana plants during strong typhoons and heavy flooding?
Almost all banana plants may be downed and a large number of trees may be uprooted. Rice and corn crops may suffer heavy losses.
What are the pests of banana?

What is killing my banana plant?
Nematodes: Nematodes are a common banana plant pest. They cause rotting of the corms and act as a vector to the fungus Fusarium oxysporum. There are a number of different species of nematode that like bananas as much as we do. Commercial farmers apply nematicides, which when properly applied, will protect the crop.
How do you protect bananas from pests?
At planting, a certain amount of insecticide such as Furadan, Pimicid, Mocap and Dursban should be systematically applied around the suckering of the planting hole. In the case of established plantations, the insecticides should be applied to the soil around the base of the banana stool.
How do you protect bananas from insects?
Bunches, pseudostem and the suckers should be sprayed chlorpyriphos.
Cultural method:
- Use thrips-free planting material or tissue-cultured bananas and, if possible, hot water treatment prior to planting.
- Destroy all the volunteer plants and that could act as a source of thrips to spread to other plantings.
What is the environmental impact of bananas?
Major environmental problems arise from the production of bananas for export or from large-scale commercial production of bananas for local markets. These include habitat conversion, soil erosion and degradation, pollution from agrochemical use, solid waste, and water usage.
How do you control banana aphids?
Aphids can be killed by their natural enemies, or with sprays of registered insecticides, or with insecticidal soaps or liquid dish washing detergents and vegetable oils (see below). Ants protect the aphids from their enemies, and ants feed upon the sweet honeydew that aphids produce.
What might be the effects to the plants during strong typhoons and heavy flooding?
Excessive rain can cause plants to drown, and it also causes soil erosion.
Why is my banana plant rotting?
The disease is caused by a subspecies of the soil-borne bacterium Pectobacterium carotovorum. It survives in moist soils and in crop debris. It is spread between trees via rain and irrigation water but also by infected plant material. Mainly young plants (root suckers) are affected by the disease.
What is eating my banana leaves?
The banana weevil (Cosmopolites sordidus) is an invasive insect that infests banana trees, feasting on the trunk and leaves. The weevil hides inside the leaf sheath during daylight hours and does its damage in darkness. The banana weevil is native to southeast Asia but is now found in banana crops around the world.
Do banana trees attract pests?
For the home grower, however, spider mites (Tetranychus urticae Koch) and banana aphids (Pentalosa nigronervosa) are the most likely banana tree insect pests. Spider mites can become a problem with container-grown banana trees when brought indoors.
How do I save my banana plant?
Give it a good watering in the spring to encourage new growth. It may not get as big as a plant that overwinters with its stem, but at least it will be alive for a new season. Hardy banana tree types will normally come back fine but may need pruning of any dead growth if it was left on.
Why is my banana tree dying?
The first step to returning the banana plant to full health is to determine what’s wrong. Both too much and too little water can stress the plant, resulting in leaves turning brown due to the inability of waterlogged roots to circulate moisture and nutrients, or insufficient water for the roots to circulate.
What does banana disease look like?
yellowing of lower or older leaves, caused by the fungus blocking the water conducting tissue within the banana plant stem. lower leaves collapsing to form a ‘skirt’ around the plant. cut open, the stem is discoloured from yellow to red, through to dark brown or black, depending on how long the plant has been infected.
What are the problems in banana production?
This lack of genetic variety makes plants highly susceptible to pests, fungi and diseases, and therefore large quantities of insecticides and other pesticides are applied to the crops. In fact, bananas are sprayed with more pesticides compared to other tropical fruit because of the fruit’s thick peel.
Why do my bananas get holes in them?
So if your bananas are on the tree and cracking open, they have likely been left on too long and are overripe. If you have gotten your bananas at the supermarket, the reason for splitting is probably due to how they were processed as they were being held and ripened.
Why is my banana plant turning black?
Black leaf streak, or black sigatoka, is a fungal disease that is fostered by high humidity. Spores are spread by the wind. The first signs are red/brown spots on the underside of leaves and dark or yellow bordered spots with a gray center. Leaf surfaces eventually die, and fruit bunches do not develop properly.
Why are my banana plant leaves turning yellow and brown?
Chances are, your beloved Banana Plant is going through a state of dormancy and therefore is turning its leaves yellow and brown for a well-earned rest! Instead of tossing the specimen in the bin, simply keep it in the soil/pot and relocate the plant to a partially sunlit windowsill.
Why is my banana plant getting brown spots?
Black Sigatoka is a leaf spot disease of banana that can cut a tree’s fruit production in half. The fungal disease causes dark leaf spots that eventually enlarge and coalesce, causing much of the leaf area to turn yellow and brown.
