Got frothy flux?

treeseer

This used to be a late-May/June disease here in NC, but it recently has been popping out earlier. Common bacterial infection in the included bark between buttress roots of oak and others. I'm wondering how wide the range of this disease is--NY? CA? Rare? Common? I know there was a spectacular flow from a pine in AZ not long ago.

Is what you calling frothy flux the same as slime flux or bacterial wetwood?

treeseer

Different species of trees have different types of slime flux disease. The type that is found higher up in wounds and crotches of elms and poplars are considered relatively benign. They seldom seem to aggressively damage the bark. What damage occurs is well above ground level and considered correctable. They are located in Zones 2 and 4 as defined in Dr. Kim Coder’s Hazard Tree Evaluation form, published in 1990. On older oaks the disease is quite different; it is typically found between buttress roots. This is Zone 1, where damage and disease are considered critical. Previous physical damage or previous insect injury is seldom noted at infection sites on the trees studied. Like included bark in a crotch, the bark between buttresses seems to be squeezed. One theory is that the tree opens itself up to infection by wounding itself when bark is included, and the bacteria enter from the soil. This is confirmed by Dr. Alex Shigo in Modern Arboriculture: “Included bark between roots and root stubs are common underground infection courts.”
