Three- to four-year-old Japanese plum trees (Prunus salicina L.) in a commercial orchard of Antalya Province showed symptoms of decline in July-August 2015. The aerial symptoms were leaf discoloration and twig dieback, and most of the affected trees were leafless. Reddish brown cankers developing from the root to the stem base were observed. Latera...

Young olive trees showing wilting and trunk cankers were observed in an orchard in Antalya province, Turkey. The aerial symptoms associated with reddish brown cankers expanding from the root collar to the stem were leaf discoloration, defoliation, and twig dieback. A Phytophthora sp. was consistently isolated from necrotic root and crown tissues of...
