Abstract

Lentisk (Pistacia lentiscus L., Anacardiaceae) is an evergreen shrub that is widespread over the Mediterranean Region. The species is also cultivated as an ornamental plant in Italy. In August 2008, a survey carried out in a forest nursery in Sardinia (39°57′N, 9°13′E) revealed the presence of symptoms such as wilting and desiccation of foliage associated with root and collar rot on 1- to 3-year-old potted seedlings of lentisk. Approximately 30% of 1,500 potted plants were affected. A Phytophthora sp. was consistently isolated from infected roots on synthetic mucor agar medium. Colonies on carrot agar (CA) were stellate to slightly radiate with low aerial mycelium.
