A good approximation of the degree-days accumulated for a pest can be calculated by knowing: The identity and life cycle of the pest and the crop. When to start accumulating degree-days for a pest. The minimum and maximum temperatures at which the pest will develop. The highest and lowest temperatures in the field or orchard during pest development.
At this time of the year discussion of growing-degree days is often synonymous with annual bluegrass (Poa annua L.) seedhead control. Originally, growing degree-day (GDD) models were developed to predict when Poa annua seedheads would emerge, and the peak production period.n this article I hope to clarify, or add more confusion to, the concept of using GDD for Poa annua seedhead control. Growing Degree Day. A degree day, also known as growing degree days and heat units, is a measure of heat above a threshold for one day.
