Trees are also prone to diseases and require a proper treatment. It gets difficult to identify diseases in tree because the cause of them are microbial organisms and they spread by microscopic growth and spores. Infectious tree diseases – those diseases that involve not only a tree host, but also an infectious pathogen such as certain fungi, bacteria, nematodes, phytoplasmas or viruses – are among the most vexing maladies that we deal with.
Trees and woods are crucial. They provide homes for wildlife, clean air and water, food and fuel. But they’re under threat. A proper tree care should be taken to cure them from these diseases. Tree diseases can affect any part of the tree, including the tree as whole. For example, we have leaf spot, leaf blotch, needle cast, scab and blister, defoliation and yellowing or chlorosis as named symptoms.
