Base temperatures used in calculating GDD vary depending on the type of plant or pest that is being monitored. This number represents the temperature at which you will typically begin to see plant or pest growth. The base temperature most often used in USA calculations is 10°C, because it is the temperature when active growth begins for most organisms. However, in the UK’s cooler environments many turf managers use 6°C, occasionally 0°C is used as the base temperature. For more information on which base temperature best suits your turf management plan, please contact your local Syngenta contact.
