DARD Blight-Net is a decision support system to assist in the control of Potato Blight. Using weather data from a network of local weather stations, it provides area-based information on the risk of blight infection. This can help growers achieve more effective blight control with the optimum use of fungicides.
For latest information on crop management see Crop Monitor and Crop Management Notes.
  • The risk of blight infection is low if there are fewer than 11 risk hours in a 24 hour period.
  • There is an increased risk of blight infection if there are 11 or more risk hours in a 24 hour period.
  • There is a high risk of blight infection if there are 2 or more consecutive 24 hour periods that contain 11 or more risk hours each. This corresponds to a Smith Period. Apply blight fungicides at the intervals recommended for high risk conditions over the duration of such periods
