Background. Bacterial overgrowth syndrome (BOS) is a term that describes clinical manifestations that occur when the normally low number of bacteria that inhabit the stomach, duodenum, jejunum, and proximal ileum significantly increases or becomes overtaken by other pathogens.
Bacterial Canker. Bacterial canker is caused by bacteria. The disease has symptoms similar to leaf spot. But bacterial canker produces cankers that ooze a gummy substance during late spring and summer. Spots on infected leaves are dark brown and often surrounded by yellow.Outbreaks of bacterial canker generally occur after cool, wet weather. To control bacterial canker, remove diseased branches when the tree is dormant and spray with a fungicide that contains basic copper sulfate in the fall.lack knot is a fungus that grows exponentially during wet spring weather. The disease causes hard, black, swollen lumps, called galls, on the twigs and branches of the Japanese weeping cherry. The knots cut off the flow of nutrients and water to the branches, leading to wilting, stunting and dieback.
