Swollen Potato Lenticels: What Are They and How to Manage Them

Have you ever encountered a potato that has bumps on its surface? These bumps are called lenticels, and they are commonly found in potatoes. However, some potatoes may have swollen lenticels, which could be an indication of a bigger problem. In this article, we will discuss what swollen potato lenticels are, why they occur, and how to manage them.

What Are Swollen Potato Lenticels?

Swollen potato lenticels are raised bumps or blisters that appear on the surface of the potato. Lenticels are small pores in the skin of the potato that allow air to enter the tuber. While lenticels are normal, they should not be raised or swollen.

Swollen lenticels are often a sign of stress or damage to the potato. They can also be a symptom of disease or poor storage conditions. If left unchecked, swollen lenticels can lead to rotting or decay of the potato.

What Causes Swollen Potato Lenticels?

Swollen potato lenticels can be caused by several factors:

• Waterlogging: If the soil that the potato was grown in has poor drainage, excess water can accumulate around the roots. This can cause the plant to produce more lenticels, which can result in swollen lenticels.
• Stress: Potatoes that are exposed to extreme temperature changes or drought conditions can develop swollen lenticels as a response to stress.
• Insects and Pests: Insect infestations and damage from pests like rodents can cause damage to the potato's skin, which can result in swollen lenticels.
• Fungal and Bacterial Diseases: Certain fungal and bacterial infections can cause swollen lenticels. For example, black dot disease is a fungal disease that causes small black spots to form around the lenticels, which can then become swollen.
• Poor Storage Conditions: Potatoes that are stored in humid or damp environments are prone to developing swollen lenticels.

How to Manage Swollen Potato Lenticels

If you notice that your potatoes have swollen lenticels, it is important to take action to prevent further damage. Here are some steps you can take to manage swollen potato lenticels:

1. Check for Disease and Pests

If your potatoes have swollen lenticels, check for signs of disease and pests. Look for black spots, discoloration, and other abnormalities. You may need to consult a professional if you suspect that your potatoes are infected.

2. Improve Soil Drainage

If waterlogging is the cause of swollen lenticels, you may need to improve the drainage of the soil. This can be done by adding organic matter to the soil or installing drainage tiles.

3. Store Potatoes Properly

Potatoes should be stored in a cool, dry, and well-ventilated area. Avoid storing them in humid or damp environments, as this can promote the growth of bacteria and fungi.

4. Control Temperature and Humidity

Keep the temperature and humidity levels consistent in the storage area. Fluctuations in temperature and humidity can cause stress to the potatoes, which can result in swollen lenticels.

5. Handle Potatoes Carefully

Handle potatoes carefully to avoid damaging their skin. Rough handling can cause bruises and cuts, which can lead to swollen lenticels.

Swollen potato lenticels are a common problem that can be caused by various factors. If left unchecked, they can lead to rotting and decay of the potato. By taking the appropriate measures, such as improving soil drainage, storing potatoes properly, and handling them carefully, you can manage swollen potato lenticels and prevent further damage to your crop.
