Root/Crown Diseases (Pythium, Phytophthora)

Pythium and Phytophthora species cause root, crown, and stem rots. They are highly favored by high fertility and excess moisture. They require entirely different chemicals than the true fungi and are difficult to control. Preventive drenches at transplant and at regular intervals are recommended.
