Many fruit plants have a chill hour requirement for breaking dormancy. Various models estimate chilling, but two models are commonly used for fruit crops. From 2000 to 2016, chill hour data were collected by Mississippi State University experiment station employees as well as by local fruit producers; however, the number of participants in the process dwindled over time. To address this issue, we developed a mobile-friendly web application to interface with Weather Underground data. From these data, fruit growers can assess growing conditions that affect plant physiology and prepare for events in the upcoming season. Extension professionals can introduce the app to fruit growers in their areas.
