Welcome to

Blightwatch is a collaborative service supported by the Potato Council and Industry sponsors.

The Blightwatch service providers have worked to develop this management tool which is available to farmers and other users free of charge.

Traditionally the risk of potato blight infection has been based on the calculation of Smith Periods - a system that uses hourly temperature and relative humidity recordings. However, until now Smith Periods have been calculated for only a limited number of Met stations around the country.

The Blightwatch service now covers the whole of the UK down to individual postcode level. The service operates in conjunction with AHDB Potatoes - Fight Against Blight! - service and delivers daily email and optional SMS alerts if blight risks are identified in your selected area(s).
