The sudden oak death disease starts in the trees when the air carrying fungi settle on any part of the tree. This disease is very critical as it will not only adversely affect the oak trees but also harms the other trees and plants nearby.
Until now, more than one million oak trees and tanoak trees are declined during the last decade. Also, hundreds of other tree and plant species are susceptible to this fungus. Thus, it is an emerging tree healthcare problem, and hence an effective sudden oak death treatment is crucial.
