This test for Strawberry Red Core (Phytophthora fragariae) in soil allows for the detection of the disease in the ground before planting.

Plants infected become stunted with less growth and smaller fruit. The causal pathogen is able to stay within contaminated soil for long periods of time.

Cultivated raspberries and strawberries are especially susceptible to red core. This fungus-like pathogen infects strawberries, infecting rootlets, causing the roots to rot from root tip upwards, leading to a characteristic reddening of the inner portion of the root. The pathogen can be introduced with infected planting stock or contaminated equipment.
