GIS for Late Blight Research
object.jpg 1.39 K
Current GIS research on late blight aims to:
  • characterize geographic differences in the disease system,
  • assess production risks,
  • forecast the impact of new technology and resistant cultivars.

The GIS for the integrated disease management of late blight incorporates spatial information on agricultural production, historical data on weather patterns, and data generated by simulation models.

The data shown on the first three pictures are combined to identify production zones in Peru with a high risk of late blight damage. The GIS has also been used to design a scheme for collecting samples of Phytophthora in-festans, the fungus that causes the disease on these processes.
