Leaf spot of cherry laurel
Prunus laurocerasus L.
A complex of cherry laurel diseases manifesting as shot-hole symptoms due to the necrosis and abscission of affected tissues. It is caused by a range of bacterial and fungal pathogens, including Pseudomonas syringae pv. syringae and Wilsonomyces carpophilus.
In the reference 5 varieties crop Cherry laurel, where this is mentioned in the description.
In cherry laurel, the term leaf spot encompasses a group of symptoms often referred to as shot-hole. The causal agents include the bacteria Pseudomonas syringae pv. syringae, which causes spots with yellow halos, and Xanthomonas arboricola pv. pruni, which forms angular gray lesions, as well as the fungi Wilsonomyces carpophilus, Trochila laurocerasi, Eupropolella britannica, and Neofusicoccum parvum.
The symptomatology includes three stages: the appearance of primary necrotic or chlorotic spots, the formation of an abscission layer around the lesion, and the shedding of necrotic tissue, which creates characteristic holes. The pathological process may be accompanied by the development of cankers on stems and premature leaf drop.
