Bacterial Canker

Description:

Bacteria are tiny living beings (microorganisms) - they are neither plants nor animals - they belong to a group all by themselves. Bacteria are tiny single-cell microorganisms, usually a few micrometers in length that normally exist together in millions.The affected roots are killed, causing the tree to remain stunted, with leaf yellowing and early leaf drop. This canker can develop collar rots at ground level, developing firm, jelly-like, oozing lesions Symptoms are similar to bacterial canker, except that summer canker occurs during summer, with lesions starting at the base of the tree and moving up, while bacterial canker occurs mainly in late autumn, with lesions occurring in the upper part of the tree. This disease is favoured by waterlogged soil and poor drainage.
