Blueberries face a challenge from Phytophthora cinnamomi, resulting in root rot, especially when grown in moist soils. This particular pathogen thrives in warmer climates but struggles to survive in soils that undergo deep or repeated freezing during winter. Exhibiting a wide host range, this fungus-like organism infects various tree and shrub species, including ericaceous plants like rhododendron and madrone, along with diverse conifers.
Within the Phytophthora genus are plant pathogens, many of which can cause severe diseases affecting important food crops like soy, potato, and tomato. With more than 800 identified species, Phytophthora has the capacity to trigger root rot in over 900 plant species worldwide.
Blueberry roots, which require abundant moisture, become susceptible to this disease when subjected to prolonged excessive wetness. Signs of wilting and apparent nutrient deficiencies in infected plants serve as indicators of compromised root function.
