Bananas produce antimatter7/9/2023 If infection occurs late in fruit production, the buds dry and blacken. The first signs of infection are yellow leaves that later brown and die. Sometimes, banana plant diseases are transmitted via insect pests but not in every case.īanana bacterial wilt may be transmitted by insects, but also by farm equipment, other animals, and on infected rhizomes. Otherwise, the land must be left fallow for up to three years. Nematicides, when properly applied, can protect a crop. There are many different types of nematodes, but they all love to feed on banana plants. Nematodes are a major problem amongst banana growers. ![]() Several different types of thrips are known to infest banana trees and can be controlled using insecticides, soapy water, and oil.

They attack many hosts, including coconuts. Treat the plant with neem powder to reduce their population and apply insecticide at the time of planting to control weevils.Ĭoconut scale isn’t just a banana plant problem. Eventual destruction and plant death follows. They tunnel through the corms, which can cause plants to wilt and topple over. Plant virus free material next time, control aphids, and remove susceptible host plants including weeds from around the tree.īanana weevils are nocturnal pests that slow plant growth and reduce fruit yields. If the banana becomes afflicted with banana mosaic, it is best to destroy it. Fruit will be distorted, sometimes with chlorotic streaking as well. This disease also presents with chlorotic mottling or stripes on foliage. That or plant less susceptible cultivars.Īphids can also transmit banana mosaic disease. There are no chemical controls to protect against the transmission of banana bunchy top, so the only control method is to prevent the transmission by ridding the plant of the aphids. Insecticides, soapy water, and horticultural oil can help mitigate the population of aphids, but if the plant already has bunchy disease, it is best to destroy the plant. The aphid population is often tended to by ants, so control of the disease involves treating for ants. The pest may also transmit banana bunchy top disease to the plant, resulting in chlorotic leaf margins, brittle leaves, and, as the name suggests, a bunchy top. An infestation of these aphids causes curled, shriveled foliage. These pests are soft-bodied, wingless, and almost black. ![]() Control of pests on bananas requires early identification.īanana aphids are an example of a pest that acts as a vector of disease. Some of these banana pests act as vectors of disease as well. There are quite a number of banana tree insects that can cause minor damage to a single plant or wreak havoc through an entire plantation. Any of the problems affecting bananas may afflict the home gardener as well, so it’s important to learn to identify banana pests and diseases so you can nip them in the bud. Any number of banana pests and diseases can derail a successful plantation, however, not to mention environmental banana plant problems such as cool weather and high winds.
