Whole plant field inoculation of seven Phytophthora species on two Rhododendron cultivars using wound inoculation. Graphs show area under the lesion expansion curve (AULEC) in mm2 × days for each Phytophthora spp. at each seasonally observed temperature (inset C) of 4, 8, 15, and 18 °C, on A, Rhododendron cv. catawbiense ‘Boursault’, and B, Rhododendron cv. ‘Lee’s dark purple’. Inset, C, shows the temperatures (°C) measured during each of the four experiments. Bars show standard deviation, lower case letters represent statistically significant differences based on Tukey’s test at the 95% confidence level (based on transformed data)
