How do I start using the Late Blight Risk Modeling Site?
The Late blight Risk Model predicts the first occurrence of potato late blight and its subsequent spread based on seasonal accumulation of severity values (DSV’s; see the Explanations page for more details). Accumulation of severity values should start at plant emergence. In our model we start accumulating severity values on May 1st, but you can select your own emergence date using the “Calculate your own” emergence page. To start using the Late Blight Risk Modeling site just select the marker on the map that is closest to your location. It will pop up a dialogue with the Risk Level for your area, and you can click on it to get a spray recommendation for your area. Or as mentioned above you can use the “Calculate your own” page to get a personalized recommendation.
