Weeping willow diseases and symptoms can be found in the home guides.
There are three diseases of willows in the UK.They can make the trees unattractive.
There are brown or black spots on the leaves that may be distorted.Affected leaves and shoots are often shed, leading to a sparse crown Scab: Irregular black spots appear on new season's growth, causing black, shrivelled shoots Black canker: Symptoms appear later in the season and the shoot die
Raking up leaves from trees that have anthracnose will only be of limited value because the most important source of the disease is on the tree's leaves.When the stems are small, bark infections are more severe.Other willow species are unaffected by the resistance of sepulcralis and S. 'Erythroflexuosa'.The name of the plant is Salix alba var.There are three plants that are resistant to one or both of black canker.It would not be feasible to spray mature trees if there were chemical controls for these diseases.There are three fungicides that are labeled for the control of other diseases on ornamental plants.The control of both insect pests and disease can be achieved with the following products: myclobutanil, Rose Shield Bug & Fungus Killer and Roseclear Ultra Gun 2.A product's inclusion doesn't mean a recommendation or endorsement by the RHS.There is a list of products for the home gardener.Pesticides for gardeners can be downloaded from the Adobe Acrobat PDF document.

Chemicals are used safely and effectively.
The affected tissues are affected by the diseases.The diseases are the worst in wet weather.The golden weeping willow is susceptible to attacks of anthracnose.The disease can leave the tree almost leafless, but it has little effect on other willows.
The shoots killed by the last two diseases remain on the tree, whereas anthracnose-infected tissues are shed.The most important source of anthracnose in the following years is the shoots that remain on the tree, since the spores they produce are very easy to find.
