Lesion: A localized area of damage or injury on a plant, often caused by diseases, pests, or environmental stress.
Lesions are like wounds on a plant, indicating that something is amiss. They can appear as spots, blotches, or sunken areas on leaves, stems, fruits, or other plant parts. Lesions can be caused by various factors, including fungal or bacterial diseases, insect or mite infestations, or even physical damage from sunscald or hail. Identifying the cause of a lesion is crucial for determining the appropriate treatment and preventing further damage.
For home gardeners, recognizing and addressing lesions is an important part of plant health care. Observing your plants regularly for signs of lesions can help you catch problems early on. If you notice lesions, consider possible causes, such as recent weather events, pest activity, or signs of disease. Consulting with a local gardening expert or extension service can help you diagnose the problem and determine the best course of action. Prompt treatment can often prevent the spread of diseases or further damage to the plant.
