Pythium spreads by the movement and growth of mycelium and spores from plant to plant. Pythium thrives in hot and humid weather typically day temperatures of 80 °F to 95 °F in areas that have little air movement but high moisture content. [3] In lower temperatures of 55 °F to 65 °F and extended periods of wet weather Pythium is still prevalent.
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology. GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.
