Feb 2, Bacterial wetwood sometimes called slime flux is a water-soaked condition of wood, occurring in the trunk, branches and roots of many shade and ornamental trees and more often trees over ten years old.
Wetwood is most prevalent in Siberian and American Elm but can attack numerous other trees. The disease occurs in the crotches or where there are wounds on trees.
This disease is a major cause of rot in the trunks and branches of hardwood trees. Slime flux is caused by a bacterial infection in the inner sapwood and outer heartwood areas of the tree and is normally associated with wounding or environmental stress, or both.
In elm trees, bacteria Enterobacter cloacae are the cause of slime flux, but numerous other bacteria have been associated with this. Bacterial Wetwood. Bacterial wetwood on elm (Ulmus) Bacterial wetwood, also known as slime flux, is caused by an infection of one or more of several bacteria.
It results in a water-soaked, oozing or bleeding condition of wood, which occurs in the trunk, branches and roots of shade and ornamental trees. It is normally not serious in most trees but is a chronic disease, which causes. The elms in our area commonly ooze from a disease known as Bacterial Wetwood or Slime Flux.
It does not kill the tree, but it can be a nuisance during the growing season as the tree drips water from the truck. I have attached a link to a fact sheet with more information. The branch connection shows that there may be included bark. Following an introduction to elms and their cultivation, a detailed account of biotic diseases includes wilts, yellows, bacterial wetwood, cankers, foliar diseases, root rot and damping-off, discoloration and decay, virus and virus-like diseases and mistletoe disease.
Abiotic diseases include nutrient deficiency, meteorological factors, chemical toxicity and mechanical damage.

disease. The microorganisms that have been associated with disease are commonly found in soils and probably enter through wounds above and below the soil line. Over a period of time, which may be several years, the number of microorganisms increases in the wood, causing the water-soaked symptoms of wetwood.
Large amounts of gases may. Do not prune elm trees between mid-April and mid-October. Disease, pests, and problems. European elm flea weevil is a minor problem. Wetwood can occur. Disease, pest, and problem resistance. Very good resistant to Dutch elm disease, elm yellows and elm leaf beetle.
Native geographic location and habitat. Of hybrid origin. Bark color and texture. It is associated with ring shake and honeycomb, two lumber defects.
Ring shake in elm leads to the term “onion elm” in the lumber trade. Another bad outcome of wetwood, which occurs in a small subset of species, is a condition known as slime flux [3, 6, 10]. This occurs when the gasses produced anaerobically by the bacteria cause pressure to build up, expelling the liquid, which may damage.
Dutch Elm Disease (fungus – Ceratocystis ulmi): Symptoms may appear on one or more branches on any part of the tree in contrast to phloem necrosis where tops of infected trees show first abnormalities. Leaves on individual branches wilt and turn yellow; in some instances leaves wilt very rapidly, dry out, then fall while still green.
Fortunately, the propagation of hybrid, disease-resistant trees shows promise. Elm claims about 20 species in the temperate regions of the world.
The most well known include the stately American elm (Ulmus Americana) and the slippery elm (Ulmus rubra) of the United States, and the English elm (Ulmus procera) in Europe and Great Britain.
The most common evidence of wetwood is bleeding or “fluxing” of sap from the trunk or larger limbs of a tree. Often this fluxing is associated with a wound, but has also been observed where no obvious wound existed. Bacteria associated with wetwood are common in soil and water Stain associated with bacterial wetwood disease on the trunk.
Bacterial wetwood most commonly affects elm and poplar, but can also be a serious problem on aspen, maple, and mulberry. Bacterial wetwood leads to discolored, rancid-smelling areas on tree trunks.
What does bacterial wetwood look like. Trees suffering from bacterial wetwood are characterized by having areas where liquid oozes from their trunks. Wetwood and slime flux are common on elm.
That disease complex was discussed in issue 4 of this newsletter. There is no control for wetwood, but it is not fatal to a tree. The bacteria associated with the infection are common in our soil and probably infect from the soil.
Most old elms in the state are infected with wetwood. Yes, bacterial wetwood is most common in maple, elm, oak, poplar and birch trees.
But, since so many different bacteria can spark wetwood, it can also happen to lots of other trees. Is bacterial wetwood harmful. Damage done by bacterial wetwood depends on the condition of your tree. For most trees, the stained bark is as bad as it gets. A year-old American elm tree stood condemned, finally succumbing, it seemed, to the disease that has killed off hundreds of thousands of other elms in.
Some bacteria target specific hosts. One example is Enterobactor cloacae, which is the causal agent of bacterial wetwood in elm. Species of Clostridium, Bacillus, Klebsiella, and Psedomonas have been identified as the causal agents in various other trees.
Disease Cycle. The disease cycle begins when bacteria infiltrate the sapwood. Tree disease control service — when performed by a certified Utah arborist — can help your trees overcome the effects of slime flux.
Also known as wetwood, slime flux is a common bacterial disease that infects many popular northern Utah species, including elm. Bacterial wetwood on ornamental trees Wet wood (or slime flux) is a common condition on poplar, elm, birch, maple, apple, mountain ash and other ornamental trees.

The main symptom of slime flux (often called wet wood) is the oozing of sour-smelling sap from the tree's trunk, cracks and branch crotches. The sap is more prevalent during the spring and early summer when the tree is growing more rapidly. The sap drips down the bark and causes a gray-white streaking on the trunk and branches.
The cedar elm is susceptible to Dutch Elm disease, wetwood, blackspot and anthracnose. Dutch Elm Disease. Dutch Elm disease has decimated the elm tree population. Cedar elms are not as affected as other elm species, but are still in danger.
The disease is a caused by a fungus that is spread by the elm bark beetle as it tunnels under the bark. Wetwood, or slime flux—Various microorganisms. Wetwood is caused by several species of bacteria; yeast organisms may also be involved.
Wetwood is especially common in elm and poplar, but it affects many other plants, including box elder, fruitless mulberry, hemlock, magnolia, maple, and oak. Would that be the same as slime flux. I have Insects and Diseases of Woody Plants but it must be an earlier edition (?) because there's no mention of a flux infection on p.
but I did find a reference to Bacterial Wetwood/Slime Flux on p of my book that sounds similar. Dutch elm disease is a widespread and often fatal disease to American elm trees.
It is often spread from tree to tree through roots that have grown together. Aphids, scale, leaf miners and elm leaf beetle are common insects that also plague American elms. The Siberian and Chinese elms are often confused.Elm trees (Ulmus spp.) are one of the most widespread landscape plants, widely used as ornamental trees to embellish parks and streets of different countries including trees cultivation is seriously limited by biotic factors such as bacterial pathogens.
Recently, bacterial wetwood has been identified as a common disease on elm trees in Northwest Iran.
