Bananas may be one of the most popular fruits sold in the United States. Grown commercially as a food source, bananas also feature prominently in warm region gardens and conservatories, making striking additions to the landscape. When planted in areas with plenty of sun, bananas are not all that hard to grow, but problems with banana plants are bound to crop up nonetheless. What kinds of banana plant pests and diseases are there? Keep reading to find out how to solve problems with banana plants.
Aphids are a common pest that can wreak havoc on many plants, including the beloved abyssinian banana tree These tiny sap-sucking insects reproduce quickly and spread diseases, stunting the growth of affected plants. While chemical pesticides may seem like the easiest solution, their toxicity makes them a less than ideal choice for edible plants like banana trees
The good news is there are many effective organic and natural methods to get rid of aphids on abyssinian banana trees. In this comprehensive guide, we’ll explore several techniques to eliminate existing aphid infestations and prevent future attacks on your prized banana trees.
Identifying Aphids on Abyssinian Banana Trees
The first step is learning how to spot aphids on your abyssinian banana trees. Here are some telltale signs of an aphid infestation:
-
Small soft-bodied insects – Usually light green or black in color, from 1-3mm in length. Aphids tend to cluster on the undersides of leaves and along stems
-
Curled, distorted, or yellowing leaves – Aphids pierce plant tissues and suck out sap, causing stunted growth and discoloration.
-
Sticky honeydew residue – Aphids secrete excess sugary fluid called honeydew. Ants are often present feeding on it.
-
Presence of cast aphid skins – Look for small white molted exoskeletons left behind as nymphs mature.
Carefully inspect the undersides of leaves, stems, and developing fruits to spot aphids early before extensive damage occurs.
Organic and Natural Aphid Treatments
Once detected take prompt action against invading aphids using these safe organic remedies
1. Strong Water Sprays
Powerful sprays of water can blast aphids off leaves and stems. Focus on undersides of foliage and where branches meet the main stem. Repeat as needed until populations subside.
2. Natural Predators
Ladybugs, lacewings, hoverfly larvae, and other beneficial insects feed on aphids. Attract them to your garden by planting pollen and nectar sources like daisies, yarrow, and dill. You can also purchase live predators to unleash on infested plants.
3. Horticultural Oils and Insecticidal Soaps
These organic pesticides smother and kill aphids on contact, while being safe for most plants. For abyssinian banana trees, stick to gentle soaps and lighter horticultural oils.
4. Neem Oil
Derived from the neem tree, this traditional botanical insecticide coats plants with a residue that repels and kills aphids. Use neem oil as a foliar spray or soil drench.
5. Diatomaceous Earth
This powder composed of crushed fossils cuts and dehydrates the waxy outer layer of soft-bodied insects like aphids. Lightly dust leaves, taking care to avoid flowers.
6. Kaolin Clay
Also called white clay, kaolin clay forms a slippery barrier preventing aphids from traversing and colonizing plants. Mix with a bit of mild soap and apply to stems and leaf undersides.
7. Sticky Traps
Yellow and blue sticky cards or tape traps aphids flying in to colonize plants. Strategically place them around infested abyssinian banana trees to monitor and decrease populations.
Preventative Aphid Control Measures
Proper cultural practices can discourage aphids from attacking your abyssinian banana trees in the first place:
-
Remove heavy aphid infestations by pruning affected leaves and stems.
-
Dispose of all plant debris harboring overwintering aphid eggs.
-
Use drip irrigation instead of overhead watering to keep foliage dry.
-
Apply nitrogen fertilizer conservatively to avoid excessive succulent growth that attracts aphids.
-
Allow space between plants for airflow and sunlight penetration to slow pest spread.
-
Use a row cover, netting, or floating fabric to create a physical barrier against aphids.
-
Plant nectar-rich flowers and herbs to nourish predators of aphids like lady beetles and lacewings.
-
Use reflective mulches like aluminum foil under abyssinian banana trees to confuse and repel incoming aphids.
-
Apply kaolin clay or horticultural oils before bud break in spring to deter aphids.
Aphids can be challenging to control but are rarely fatal to established abyssinian banana trees. Implementing organic sprays, introducing predators, and improving cultural practices are effective long-term solutions for protecting your banana grove. Consistent monitoring and early intervention at the first signs of infestation are key to keeping abyssinian banana trees lush, productive, and free of sap-sucking aphid pests.
Growing Banana Plant Problems
Bananas are monocotyledonous herbaceous plants, not trees, of which there are two species– Musa acuminata and Musa balbisiana, native to southeast Asia. Most banana cultivars are hybrids of these two species. Bananas were most likely introduced to the New World by southeast Asians around 200 B.C. and by Portuguese and Spanish explorers in the early 16th century. The majority of bananas are not hardy and are susceptible to even a light freeze. Extreme cold damage results in the dieback of the crown. Leaves will also naturally shed in exposed areas, an adaptation to tropical storms. Leaves may droop from under or overwatering while brown edges indicate a lack of water or humidity. Another growing banana plant problem is the plant’s size and propensity to spread. Keep that in mind when locating a banana in your garden. Along with these concerns, there are many banana pests and diseases that may afflict a banana plant.
A number of insect pests can affect banana plants. Here are the most common:
- 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. Otherwise, the soil has to be cleared, plowed, and then exposed to the sun and left fallow for up to three years.
- Weevils: The black weevil (Cosmopolites sordidus) or banana stalk borer, banana weevil borer, or corm weevil is the second most destructive pest. Black weevils attack the base of the pseudostem and tunnel upward whereupon a jelly-like sap oozes out from the entry point. Different pesticides are used commercially depending upon the country to control black weevils. Biological control utilizes a predator, Piaesius javanus, but has not been shown to have any truly beneficial results.
- Thrips: Banana rust thrips (C. signipennis), as its name suggests, stains the peel, causing it to split and exposes the flesh which then begins to rot. Insecticidal dust (Diazinon) or a spraying of Dieldrin can control thrips, which pupate in the soil. Additional insecticides combined with polyethylene bagging are also used to control thrips on commercial farms.
- Scarring beetle: The banana fruit scarring beetle, or coquito, invades the bunches when the fruit is young. The banana scab moth infests the inflorescence and is controlled with the use of an injection or dusting of pesticide.
- Sap-sucking insects: Mealybugs, red spider mites, and aphids may also pay a visit to banana plants.
There are quite a number of banana plant diseases that can afflict this plant as well.
- Sigatoka: Sigatoka, also known as leaf spot, is caused by the fungus Mycospharella musicola. It is most commonly found in areas of poorly draining soil and areas of heavy dew. The initial stages show small, pale spots on the leaves that gradually enlarge to about a half inch (1 cm.) in size and become purple/black with gray centers. If the whole plant is infected, it looks as if it has been burned. Orchard grade mineral oil can be sprayed on the banana every three weeks for a total of 12 applications to control Sigatoka. Commercial growers also use aerial spraying and systemic fungicide application to control the disease. Some banana cultivars also show some resistance to Sigatoka.
- Black leaf streak: M. fifiensis causes Black Sigatoka, or Black Leaf Streak, and is much more virulent than Sigatoka. The cultivars that have some resistance to Sigatoka show none to Black Sigatoka. Fungicides have been used to try and control this disease on commercial banana farms through aerial spraying but this is costly and difficult due to scattered plantations.
- Banana wilt: Another fungus, Fusarium oxysporum, causes Panama disease or Banana Wilt (Fusarium wilt). It begins in the soil and travels to the root system, then enters the corm and passes into the pseudostem. Leaves begin to yellow, starting with the oldest leaves and moving in towards the center of the banana. This disease is lethal. It is transmitted through water, wind, moving soil, and farm equipment. On banana plantations, fields are flooded to control the fungus or by planting a covercrop.
- Moko disease: A bacterium, Pseudomona solanacearum, is the culprit resulting in Moko Disease. This disease is the chief disease of banana and plantain in the western hemisphere. It is transmitted via insects, machetes and other farm tools, plant detritus, soil, and root contact with ailing plants. The only sure defense is to plant resistant cultivars. Controlling infected bananas is time-consuming, expensive, and resistant.
- Black end and Cigar tip rot: Black end stems from another fungus causes anthracnose on the plants and infects the stalk and fruiting end. Young fruit shrivels and mummifies. Stored bananas afflicted with this disease rot. Cigar tip rot starts in the flower, moves to the tips of the fruit, and turns them black and fibrous.
- Bunchy top: Bunchy top is transmitted via aphids. Its introduction almost wiped out the commercial banana industry in Queensland. Eradication and control measures along with a quarantine area have managed to stamp out the disease but growers are eternally vigilant for any signs of bunchy top. Leaves are narrow and short with upturned margins. They become stiff and brittle with short leaf stalks that give the plant a rosette look. Young leaves yellow and become wavy with dark green “dot and dash” lines on the undersides.
These are just some of the pests and diseases that can afflict a banana plant. Vigilant attention to any changes in your banana will keep it healthy and fruitful for years to come.
