Wilt diseases in woody plants tend to fall into two major categories, those that start with the branches and those that start with the roots.

Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non- lignified plant cells falls towards zero, as a result of diminished water in the cells . Wilting also serves to reduce water loss, as it makes the leaves expose less surface area. [ 1 ]
Leaf spots can vary in size, shape, and color depending on the age and type of the cause or pathogen. Plants, shrubs and trees are weakened by the spots on the leaves as they reduce available foliar space for photosynthesis. Other forms of leaf spot diseases include leaf rust, downy mildew and blights. [4]
