This disease could be confused with cold injury or spider mites. Symptoms Needles turn dull green to light brown to reddish-brown on smaller branches or twigs scattered over the plant.
Twigs gradually die back from the tips.
Old and new leaves and twigs may be involved. Red cedars are especially susceptible to this disease. On highly susceptible hosts, the fungus may invade and girdle larger stems, resulting in browning and death of major branches. In very severe cases, entire plants may be killed.
