Plant NameTypeDescription 
Physiological shotholeLaurelDiseaseShothole symptoms resulting from cultural or environmental stress are commonly observed on laurels. Research has failed to identify what specific stress is responsible. Symptoms are first observed as necrotic leaf spots with circular to irregular margins. Abscission layers develop around necrotic leaf spots causing the injured tissue to drop away, leaving holes and tattered areas in the leaf. After tissues drop, most often it is difficult to determine what caused the initial injury. Observations of early symptom development, signs, and symptoms on other areas of the plant may help make an accurate diagnosis.
Carnation tortrixLaurelInsectPortuguese laurel (Prunus lusitanica) is sometimes infested with the larvae of the carnation tortrix, a small bell-shaped brown moth with reddish underwings and dark bands on the upper wings. The larvae feed by rolling leaves and tying them with webbing. The caterpillars are light brown or greenish with brown heads and about 1/2" to 3/8" long at maturity. The larvae are very active when disturbed. The carnation tortrix attacks many broad-leaved evergreen plants, but seldom causes serious damage.
