Tree Health 101: Fungi, Bacteria, and Viral Impacts

Written by Moon Valley Nurseries | 10/20/2023
When it comes to tree health and issues, it is essential to understand the distinctions between fungi, bacteria, and viruses. These three microorganisms can cause harm to trees, but they operate differently, and their impact varies. 
 
Fungi are one of the primary culprits behind tree diseases. They are multi-cellular organisms that thrive in warm and moist environments. They can be both beneficial and detrimental to trees, depending on the species. Fungi obtain their nutrients by breaking down organic matter, such as dead wood. However, certain fungal species can attack live trees and cause diseases like root rot, cankers, and powdery mildew. Moon Valley Nurseries knows it’s crucial to identify and treat any fungal infections promptly to prevent the spread to other trees.
 
Bacteria are single-celled organisms that can either be beneficial or harmful to trees. There are good bacteria that can promote tree health and growth, aiding in nutrient absorption and disease prevention. However, there are also harmful bacteria that cause diseases like fire blight and bacterial leaf scorch. These diseases can lead to significant damage and even death of the infected trees. At Moon Valley Nurseries, it’s vital to maintain a proper balance of beneficial bacteria and monitor for harmful bacteria to protect the overall tree health.
 
Viruses, unlike fungi and bacteria, are not considered living organisms. They are essentially genetic materials enclosed in a protein coat. Viral infections in trees can cause a range of symptoms, including yellowing leaves, stunted growth, or abnormal barks. The transmission of tree viruses primarily occurs through vectors like insects or infected pruning tools. While scientists are still studying the full extent of viral impact on tree health, it’s evident that early detection and prevention are crucial. Moon Valley Nurseries implements strict hygiene practices and regular monitoring to prevent viral infections on our farms and in our nurseries.
