root rot

Root rot is a plant disease characterized by the decay of a plant's roots, primarily caused by soil-borne fungi and other microorganisms like Oomycota. Plants affected by root rot often show a loss of vigor, stunted growth, yellowing leaves, and wilting, and they may not respond to fertilization or watering. This condition can lead to the gradual death of trees and other plants.12

Preventative measures include using disease-free or resistant plant varieties, ensuring well-drained soil with ample organic matter, and practicing crop rotation for annuals and biennials. Proper plant care, such as adequate fertilization and watering, along with controlling pests and weeds, also helps maintain plant health and prevent root rot.1
