Figure 1: Typical PRR “hotspot” with the frontmost tree showing the beginnings of PRR symptoms with PRR-killed Fraser fir in the behind it. The bright lime-green foliage is often the first symptom seen in Fraser fir to PRR, though may also be due to nutrient deficiency. Identification of other PRR symptoms present can help to confirm PRR diagnosis.
