There are several synonyms for the term "abnormal plant swelling." Some of these include plant tumors, plant galls, plant knots, plant cysts, and plant burls. These abnormalities in the plant are often caused by viruses, bacteria, fungi, or insects that invade the plant's tissues and disrupt its growth patterns. Although they may look unsightly, some plant swollen growths are harmless, while others can cause serious damage to the plant's health. Understanding the different types of abnormal plant swelling and their causes can help gardeners and farmers take appropriate measures to prevent their plants from developing these growths and maintain healthy, productive plants.
