Slime flux occurred mainly from bark cracks at the bottom four meters of the tree base. Analyses showed that slime flux incidence was positively correlated with tree age, and that incidence differed among tree species, with greater incidence in parks than in forests. Can we reseed the area or do we need to wait a period of time before reseeding Lorrie Buirge 1241 Upton Ave. The grass that is under the tree dripline is dead and/or dying. Among over 1700 trees inspected, 44 had visible signs of slime flux. We have what we believe to be an elm with wetwood that is producing slime flux. Bacterial wetwood, also known as slime flux, is a visually frightening-looking, but typically non-lethal, disorder of many types of deciduous trees. Slime flux, or wetwood, is a bacterial disease of mature deciduous trees, including oaks, elms, tulip poplars, maples, redbuds, and dogwoods, among others. If slime flux was observed, then source of the flux was also recorded. Local forests and parks in Southern Ontario were surveyed systematically in transects, targeting 100 trees per transect. This wet material is sometimes colonized by fungi and other bacteria and can smell bad. The sap drips down the bark and causes a gray-white streaking on the trunk and branches. The bacteria and yeast may live on sap nutrients within injured trees for many years without any outward evidence. The sap is more prevalent during the spring and early summer when the tree is growing more rapidly. Slime flux is caused by common surface-inhabiting bacteria or yeast fungi that enter the trunk through wounds associated with improper pruning, stem breakage, injections, cracks from freeze injury or weak limb crotches. Symptoms include the bleeding or oozing of clear slime from the tree causing dark streaking on the trunk or branch crotches. 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 research conducted here in Ontario, Canada used a visual survey to estimate the occurrence of slime flux in deciduous tree species. Bacterial wetwood or slime flux is a common disease of many hardwood trees, such as maple, elm, cottonwood, and aspen. DAMAGE/SYMPTOMS Bacterial wetwood often develops in the roots or the lower part of the trunk but may also affect branches. HOST Aspen, cottonwood, elm, boxelder, maple, oak, linden, cherry, honeylocust, fir, poplar. While wetwood is a well-studied subject because of its potential negative impacts on lumber quality, there is a paucity of research on the biology, ecology and distribution of slime flux. Several species of bacteria including Enterobacter, Klebsiella, and Pseudomonas. Bacteria, commonly found in soil and water, take up residence in young trees or gain entrance to. Heartwood deep in the interior of the tree is much darker than surrounding sapwood. The phenomenon of wetwood exudates forming streaks down the bark is known as slime flux. Bacterial Wetwood Or Slime Flux Symptoms and Signs. Wetwood is caused by the bacterial infection of the heartwood of deciduous trees which creates a build-up of pressure within the tree and causes fluid to be exuded.
