FIGURE 2 Pathogenicity of Phytophthora palmivora (isolate 23-1093-R) to potted Edgeworthia chrysantha plants in a greenhouse at the end of Trial 1. Symptoms on shoots and roots were evaluated 84 days after not being inoculated (A and C) or after being inoculated (B and D). Plants were grown from rooted cuttings and varied naturally in size.
