This page was created as part of the AMRE – OARDC Web -Development project. AMRE is a summer research program that runs annually at the College of Wooster.
The goal of this project was to create an interactive web-site that will enable a producer anywhere in Ohio to input his/her 5-digit zip code and obtain information as to which insect/pest he/she needs to spray for and when. The US government is currently trying to reduce the number of sprayings due to environmental concerns. Presently growers usually spray their nurseries every five days. This web-site provides a list of the phenological events as and when they occur, so that better pest management decisions can be made.
There are certain plants that are known as indicator plants. Observing the life cycle patterns of these plants, and the insects and pests associated with them has revealed that certain lifecycle stages of these organisms correspond to a certain Growing Degree-Day value. Growing Degree-Day is a measure of the growth and development of plants and insects and it is directly related to the daily maximum and minimum temperature. The GDD of any zip code location in Ohio is estimated using the GDD of ten OARDC weather stations. Using the latitude and longitude of the zip code location entered and that of the ten weather stations, the distance of the site is calculated from each of the ten weather stations. The distance formula used is weighted to include factors like the difference between North-South and East-West variation in temperature. We then use these individual distances and the GDDs of the ten weather stations to estimate the GDD of the site. Combining the database of lifecycle pattern information of indicator plants and insects and the daily growing degree day value calculated, the web site is able to make a fairly accurate estimation of all the phenological events that are likely to occur on or around a particular day.
