Bacterial wetwood or slime flux is a common disease of many hardwood trees, such as maple, elm, cottonwood, and aspen. As determined by Dr. Alex Shigo's research, the best current advice is to maintain the tree's overall health so that the tree can isolate the spot and grow good wood around the diseased portion. There is still some debate about this practice, but the consensus now is to refrain from drilling holes. These gases build up pressure causing movement of interior liquids to the exterior of the trunk where they escape through wounds and cracks. That's the result of the . Another disease that also causes bleeding, called alcoholic flux, affects primarily willows. In willow, the bacteria tend to be limited to the tissue between the outer bark and the wood called the cambium. We teach, learn, lead and serve, connecting people with the University of Wisconsin, and engaging with them in transforming lives and communities. Slime flux, also known as bacterial wetwood, is caused by infection with a single or more bacteria. Bacterial wetwood (bacterial slime, slime flux) is a common disease that affects the central core of many shade and forest trees. In willow trees, the trunk or sections of a branch may froth or bubble with cream-colored foam with a distinct acidic, fermenting odor. 1 Bacterial wetwood is a common disease that affects the central core or bark of many shade and forest trees. If, however, the area is small, shape the bark removal with clean, smooth edges. The disease also affects species of apple, ash, birch, cherry, fir, honeylocust, linden, maple, oak, sycamore, plum, and poplars. When stressed or wounded, or if the pressure becomes too intense, the bark will release the wetwood fluid at any weak point, especially at wounds. An example of data being processed may be a unique identifier stored in a cookie. Alcoholic flux is primarily found in willow trees. Without immediate treatment, this bacterial disease spreads rapidly and affects other plants nearby. Slime flux is most common on large, older trees and in spite of its smell it is to some extent beneficial to the tree. There are several species of trees susceptible to it, and elm is definitely one of them. The other comment is correct about bacterial wetwood/slime flux. The emitted sap may have a reddish No effective methods exist to eliminate wetwood disease. Internally, bacterial wetwood can be associated with localized areas of wood decay. To limit the unsightly staining of bark caused by bacterial wetwood, try to identify where the ooze is exiting from the trunk and insert a long, plastic tube at this location to direct the ooze away from the trunk and to the ground at the base of the tree. Bacterial Wetwood (Slime Flux) in Trees by Carmen Sanogo, Department of Plant Pathology It is the time of the year when wetwood or slime flux might be observed on infected trees. They can be spread by absorption through wounds on roots, pruning cuts and wood-boring insects. Slime flux is identified by dark liquid streaks running vertically below an injury and a foul-smelling and slimy seepage running down the bark. In other cases, as with elm and cottonwood, infection results in wet gray to brown areas on limbs and trunk. Slime flux is caused by the infection of sapwood by several different bacteria. In the forest, practices that minimize wounding will reduce the spread of this disease. The long part of the oval should be parallel with the trunk or limb. This thick, slime-like fluid is often dark in color as it streams down branches or the main trunk. This site is maintained by Center for Agriculture, Food and the Environment in the College of Natural Sciences. Furthermore, if the slime flux continues to flow over a number of years, the liquid that is toxic to other organisms can discolor the bark, kill moss and lichens on the .

Keeping the tree healthy and practicing proper pruning techniques and plant health care are the best ways to keep the tree from being affected by this bacteria. There are no good control measures for wetwood. When that pressure builds, it creates cracks in the tree from which to escape, and with the cracks comes sap from the inside of the tree. 656 - Bacterial Wetwood and Slime Flux of Landscape Trees: . Affected trees will usually overcome the problem themselves and seal off the damage. Many such approaches have encouraged the drilling of holes in affected trees. Experience has often proven such methods to be ineffective. The liquid kills grass and other herbaceous plants that it contacts at the base of the tree. Affected wood dries much more slowly than wood taken from wetwood-free trees. In simple terms, slime flux can be described as opportunistic pathogens that take advantage of weakened trees. Root tissue also can exhibit wetwood symptoms as brown streaks extending from the diseased trunk into the center core and sometimes the outer wood of roots. This proactive strategy ensures that trees are protected from slime flux and other diseases. Chemically, the weeping liquid is actually fermented sap, which is alcohol-based and toxic to new wood. Bacterial wetwood, also known as "slime flux", is a visually frightening-looking, but typically non-lethal, disorder of many types of deciduous trees. Most everyone has seen these symptoms in a tree at some point: an oozing, weeping spot in the bark of the tree, often near a crotch or pruning scar, but sometimes just appearing randomly. The diseases generally will not kill established trees. The pressure forces the sap out at weak points, staining the bark. ), Lelliottia nimipressuralis (Carter 1945), found by Brady et al. Flux runs down the tree trunk, killing the bark tissue it contacts. Several species of bacteria includingEnterobacter, Klebsiella,andPseudomonas, HOSTAspen, cottonwood, elm, boxelder, maple, oak, linden, cherry, honeylocust, fir, poplar. These bacteria need very little oxygen to survive and, therefore, inhabit the inner layers of sapwood and outer heartwood.
