Pineapple is a major crop in Kenya, with the country being one of the top producers of the fruit in Africa. However, the crop is facing a significant challenge in the form of plant-parasitic nematodes. These small roundworms are causing significant reductions in yields in commercial production around the world, and Kenya is no exception.
Plant-parasitic nematodes are a major pest affecting pineapple production in Kenya. These pests cause damage to the roots of the pineapple plant, resulting in stunted growth, reduced yields, and even plant death. The nematodes are particularly problematic in areas with sandy soils, which are common in pineapple-growing regions of Kenya.
Efforts to control plant-parasitic nematodes in pineapple production in Kenya have been ongoing, but the pests remain a significant challenge for growers. Effective management of nematodes requires a combination of cultural, biological, and chemical control measures. However, finding a balance between effective control and environmental sustainability remains a challenge for growers.
Overview of Pineapple Production in Kenya
Pineapple is an important cash crop in Kenya, with the country being one of the major producers of the fruit in Africa. The crop is mainly grown in the coastal region of Kenya, with the most common varieties being the Smooth Cayenne, MD2, and Sweet Gold.
Pineapple production in Kenya is mainly done by small-scale farmers, who account for about 70% of the total production. The remaining 30% is produced by large-scale commercial farms. The crop is grown both for local consumption and export, with the main export markets being Europe, the Middle East, and the United States.
Despite the growth in production, pineapple farming in Kenya faces several challenges, including pests and diseases, inadequate infrastructure, and poor market access. One of the major pests affecting pineapple production in Kenya is the plant-parasitic nematodes, which cause yield reductions and affect the quality of the fruit.

Common Pests Affecting Pineapple Production
Pineapple production in Kenya is affected by various pests that cause significant damage to the crops, leading to low yields and poor fruit quality. Here are some of the common pests that pineapple farmers in Kenya need to be aware of:
- Mealybugs: These insects are common in pineapple fields and can cause significant damage to the plants by sucking sap from the leaves and fruit. Mealybugs also excrete honeydew, which attracts ants and can lead to the growth of sooty mold.
- Nematodes: Plant parasitic nematodes are another significant pest that affects pineapple production in Kenya. These microscopic worms live in the soil and attack the roots of the pineapple plants, causing stunted growth and reduced yields.
- Fruit flies: Fruit flies are a major problem for pineapple farmers in Kenya, as they lay their eggs in the fruit, causing it to rot and become unsellable. The larvae of the fruit fly can also cause damage to the fruit, making it unmarketable.
- Thrips: Thrips are tiny insects that feed on the leaves and fruit of pineapple plants, causing them to turn yellow and become distorted. Thrips can also transmit viruses that can cause significant damage to the plants.
To control these pests, pineapple farmers in Kenya need to implement integrated pest management (IPM) strategies that involve the use of biological, cultural, and chemical control methods. These methods include the use of beneficial insects, crop rotation, soil solarization, and the application of pesticides.
However, the use of pesticides should be done with caution, as overuse can lead to the development of pesticide resistance and environmental pollution. Pineapple farmers in Kenya are encouraged to seek advice from agricultural extension officers and other experts to develop effective pest management strategies that are safe and sustainable.
Identification and Management of Pineapple Pests in Kenya
Pineapple production in Kenya is affected by various pests, including nematodes, mealybugs, scale insects, thrips, fruit borers, and bud moths. Identifying and managing these pests is crucial to ensure high yields and quality of pineapples.
Nematodes: Plant parasitic nematodes are a major problem in pineapple production in Kenya. They cause yield reductions, and there are currently no methods of controlling the disease. The pineapple variety Smooth Cayenne appears to be moderately resistant to the disease. To manage nematodes, farmers can use crop rotation, resistant varieties, and soil fumigation.
Mealybugs: Mealybugs are small, soft-bodied insects that suck sap from the pineapple plant. They secrete honeydew that attracts ants and promotes the growth of sooty mold. To manage mealybugs, farmers can use insecticides, biological control agents, and cultural practices such as pruning and removing infected plants.
Scale insects: Scale insects are another problem in pineapple production. They feed on the sap of the plant and secrete honeydew that attracts ants and promotes the growth of sooty mold. To manage scale insects, farmers can use insecticides, biological control agents, and cultural practices such as pruning and removing infected plants.
Thrips: Thrips are tiny insects that feed on the leaves and fruits of the pineapple plant. They cause scarring and deformation of the fruit, which reduces its quality and marketability. To manage thrips, farmers can use insecticides, biological control agents, and cultural practices such as removing weeds and debris from the field.
Fruit borers: Fruit borers are the larvae of moths that bore into the fruit and feed on the flesh. They cause damage to the fruit, which reduces its quality and marketability. To manage fruit borers, farmers can use insecticides, pheromone traps, and cultural practices such as removing infested fruits from the field.
Bud moths: Bud moths are the larvae of moths that feed on the buds and shoots of the pineapple plant. They cause damage to the plant, which reduces its growth and yield. To manage bud moths, farmers can use insecticides, pheromone traps, and cultural practices such as pruning and removing infected plants.
By identifying and managing these pests, farmers can ensure high yields and quality of pineapples in Kenya.
Impact of Pest Infestation on Pineapple Production in Kenya
Pineapple production in Kenya is a significant contributor to the country’s economy, with the crop being exported to various countries around the world. However, pests and diseases are a major challenge facing pineapple farmers, with plant-parasitic nematodes being one of the most significant pests affecting production.
These small roundworms cause significant reductions in yields in commercial production around the world, and Kenya is no exception. According to a report by NIBIO, plant-parasitic nematodes are one of the biggest challenges for pineapple producers in Kenya, causing yield reductions and economic losses.
In addition to nematodes, other pests and diseases that affect pineapple production in Kenya include mealybugs, scale, pineapple red mites, heart rot, root rot, fruit rot, and butt rot. These pests and diseases can cause damage to the plant’s leaves, roots, and fruits, leading to reduced yields and quality.
Pest and disease management is, therefore, crucial in ensuring high-quality pineapple production in Kenya. Farmers need to implement effective pest and disease control measures, including the use of resistant varieties, crop rotation, and the use of appropriate pesticides and fungicides. Additionally, good cultural practices such as proper soil management, irrigation, and drainage can help reduce pest and disease incidence.
In conclusion, pests and diseases are a significant challenge facing pineapple production in Kenya, with plant-parasitic nematodes being one of the most significant pests affecting production. Effective pest and disease management practices are essential in ensuring high-quality pineapple production and economic sustainability for farmers in Kenya.
