KUSA — Researchers at Colorado State University think they have found a solution to the ever-growing problem of peach trees dying due to cytospora: spraying latex paint and the fungicide Topsin.
Cytospora is a fungus that attacks tree bark and wood and kills the tree by stopping water transport. The disease typically takes about four years to kill the tree, and it doesn't affect all trees in the orchard at once.
Colorado trees are more susceptible to the fungus because of the state's cold, dry climate, which causes bark on the trees to crack, making them more susceptible to the fungus.
