What can you do about the Dreaded Tomato Blight ?
The short answer is not very much unfortunately there are currently no effective fungiscides available in the UK for the control of Blight that are liscensed for home gardeners

Blight is a disease caused by a fungus-like organism that spreads rapidly in the foliage and tubers or fruit of potatoes and tomatoes in wet weather, causing collapse and decay.
It is a serious disease for potatoes and outdoor tomatoes, but not as common on tomatoes grown in greenhouses.
Blight is specific to tomatoes, potatoes and some ornamental relatives of these two crops.
The symptoms on tomato leaves and stems are similar to those on potatoes
Brown patches may appear on green fruit, while more mature fruits will decay rapidly
Gardeners are able to access forecast warnings of when blight is active, or when there have been confirmed cases, in their region (visit the Fight Against Blight website),
Outdoor tomatoes are at high risk of infection if the weather is suitable. The disease is less of a problem under glass as the spores have to find their way into the glasshouse through doors and vents. If, however, blight establishes in a glasshouse the high humidity inside usually leads to very rapid development of symptoms.
