Degree Day Reports

Adjust the slider to select ‘planting date’ and ‘desired current date’. Early blight degree-days accumulated for the selected date range will be displayed on the radial gauge for each weather station located in the San Luis Valley.  The projected number of days to reach 650 degree-day threshold (calculated based on the average degree-days for the past seven days from the ‘desired current date’) to time initial fungicide application for early blight management will be displayed below the radial gauges. Use weather station data located nearest to your field to make management decisions.

[Location of weather stations: Center-1: Lat: 37.7067 Lon: -106.1440 ; Center-2: Lat: 37.8288 Lon: -106.0380 ; La Jara: Lat: 37.2443 Lon: -105.9722 ; San Acacio: Lat: 37.1417 Lon: -105.6110 ]
