What is MELCAST?
MELCAST is a system whereby melon growers can determine the best time to apply fungicides. The MELCAST system uses scientific and localized weather data to determine when fungicide applications are best made. Melcast Update (this web page) is intended to help muskmelon and watermelon growers keep track of daily MELCAST EFI (Environmental Favorability Index) values that are calculated for several state locations. Each issue highlights current disease problems and melon management concerns. You should choose a MELCAST Station closest to your melon operation to obtain daily EFI values:

Ask About Setting Up a New MELCAST Location:
No matter where you live, we can utilize latitude and longitude coordinates to gather daily weather satellite data that can input into the MELCAST system to generate daily EFI values. Ask us about getting a station started at your melon location.
