Phytophthora capsici can cause crown infections, leaf spots, and foliar blight in tomato. Diseased crowns are brown and soft and the plant may wilt and topple over. Another common symptom is fruit rot. Uninjured fruit of any age may be infected. Rot is most prevalent where fruit contacts the soil and begins as dark, water-soaked spots. The spot rapidly expands during warm weather and covers 50\% or more of the fruit surface with a brown, water discoloration which may assume the appearance of concentric rings. At first, the infected fruit remains smooth and firm even though the discoloration extends to its center. Over time and under humid conditions infected fruit may be covered with white fungal growth and rot entirely following invasion by secondary microorganisms.
