The 150 Rule of Pythium Disease
Most simply put - Pythium is a fungus that is a soil-borne organism. It’s out there lurking in so many of our lawns, just waiting for the perfect moment for it’s spores to flare up and spread when this pathogen is present.
Two main factors that contribute to a Pythium disease flare up are heat and humidity. This is where the “150 Rule" comes into play.
According to the 150 rule - pythium is very likely to flare up (when the pathogen is already present) when, for three consecutive days, the combined daytime temperature plus humidity levels exceed 150.
Another easy way to follow this rule is to combine daytime and nighttime temperatures. When this exceeds 150 degrees, we are in prime pythium blight disease territory.
