PP355: Stem and Fruit Canker of Dragon Fruit in South Florida

Figure 3. Symptoms of fruit canker caused by Neoscytalidium dimidiatum. The whitish-yellow spots (A, B) turn brown over time, which then coalesce to form larger lesions (B, C). The brown, dry lesions sometimes crack the peel (D), creating potential infection sites for other postharvest pathogens.
