Three methods of forecasting late blight of potato and tomato in northeastern United States

  • Published:
American Potato Journal Aims and scope Submit manuscript

Summary

Three methods were compared for possible use in forecasting late blight of potato and tomato in northeastern United States. Two of the methods were based on relative humidity and temperature data, and the other one on rainfall and temperature data.

The method using moving-graphs, derived from rainfall and temperature data, was the most successful of those tried. It is apparently reliable for this purpose.
